نقابة الزراعيين بالبحيرة

مجلس نقابة الزراعيين بالبحيرة يخاطب المسئولين للإستجابة لمطالبهم


1
السبت 07 - ابريل - 2012 -

بعد سنين مضت من التجاهل التام للزراعيين بمصر مرورا بالمشكلات التي تواجه القطاع الزراعي والتي أدت لتراجع كبير على كافة المستويات فكان الحل بضرورة إعادة الاعتبار والولاية إلى وزارة الزراعة كونها المظلة التي يجتمع تحتها جميع أطراف المعادلة الزراعية وتطويرها و العمل على راحة المهندس الزراعى .

لذلك أكد المهندس احمد العصار المتحدث الاعلامى باسم نقابة الزراعيين بالبحيرة أنه ورد إليه ما يتضمن الدعوة إلى وقفة احتجاجية مفتوحة لتحقيق بعض المطالب المشروعة من قبل الزراعيين وذلك يوم الأحد الموافق 22/4/2012 و كان على رأس تلك المطالب :

 مساواتهم فى الأجور والمكافآت والحوافز والبدلات بباقى قطاعات الدولة المختلفة مثل ( الهيئات والإدارات المركزية التابعة لوزارة الزراعة وبنوك التنمية ووزارات التربية والتعليم والبترول والعدل وغيرها من الوزارات .

و المساواة فى الرعاية الصحية للزراعيين وأسرهم أثناء الخدمة وبعدها ، وكذلك الحصول على مكافآت نهاية الخدمة مثل باقى العاملين بقطاعات الدولة المختلفة بما يضمن الحياة الكريمة فى سن الشيخوخة وذلك بقيمة شهران عن كل سنة .

كما طالبوا بنقل تبعية الزراعيين من وزارة الحكم المحلى إلى وزارة الزراعة كما كان سابقا ، وكذلك تخصيص قطع أراضى صالحة للزارعة بأسعار رمزية لجميع الزراعيين بعد انتهاء الخدمة أسوة بالعاملين بهيئة التعمير وتنمية واستصلاح الأراضى .

بالإضافة إلى زيادة بدل العدوى للزراعيين بما يوازى 25% من المرتب الأساسي ، بسبب تعرضهم للإصابة بالأمراض السرطانية وأمراض الكبد والكلى . 

و كما أشاد العصار بدور المهندس / زكريا عفيفى - نقيب الزراعيين بمحافظة البحيرة و اعضاء هيئة المكتب و فى تبنى طلبات الزراعيين المشروعة .

وبناء على ذلك تم مقابلة معالى السيد المهندس الزراعى / محمد مختار الحملاوى محافظ البحيرة الذى قام بمخاطبة كل من وزير الزراعة ، و وزير المالية ، و أمين عام مجلس الوزراء .

Solanacea العائلة الباذنجانية



البطاطس وخطورة التسمم بالسولانين




من منا لم يشاهد في يوم من الأيام عند قيامه بشراء الخضروات
بعض حبات البطاطس التي يظهر على قشرتها اللون الأخضر
دون أن يثير ذلك اهتمامنا أو تساؤلنا عن سر هذا اللون الغريب
في تلك الحبات ، ولربما أرجعه البعض منا في نفسه إلى أنه
مجرد لون بسيط قد يكون موجوداً في البطاطس التي لم تنضج بعد ،
و يمكن إزالته بالسكين أثناء التقشير ، ولا مشكلة منه .
إلا أن حقيقة هذا اللون مغايرة تماماً لهذا الاعتقاد ، وقد تكون مثيرة حقاً ،
وغير متوقعة بالنسبة لك فهذا اللون عبارة عن مادة سامة تدعى السولانين .

ما هو السولانين:


السولانين مادة تقوم بتركيبها نبتة البطاطس بشكل طبيعي
خصوصاً في الأوراق ، والجذوع لمقاومة الفطريات
والحشرات التي قد تتطفل عليها ، وللدفاع عن نفسها
من الحيوانات التي قد تتناولها فالحيوانات لا تتناول
بشكل فطري النباتات التي قد تسبب لها التسمم .

وتختار الأصناف التجارية التي تباع في الأسواق
على أساس محتواها القليل من السولانين ،
حيث يبلغ في البطاطس التجارية أقل من ( 2. 0 ) ملغ / غ ،
إلا أن البطاطس إذا تعرضت للضوء فإنها تبدأ بالاخضرار تدريجياً ،
و يكون محتوى السولانين ساماً عندما يصل تركيزه
إلى (( 1 ملغ / غ )) كما يوجد السولانين بالطبع في حبات البطاطس غير الناضجة أيضاً .

ما هي أعراض التسمم بالسولانين :
تظهر أعراض التسمم الحادة بالسولانين بعد ( 8- 12) ساعة
من تناول الوجبات المحتوية على جرعات سامة من السولانين ،
و يمكن أن تظهر بعد نصف ساعة فقط ، وتكون على شكل
أعراض عصبية ، وهضمية حادة ، وتشمل :
• الغثيان
• الاسهال
• التقيء
• تشنج المعدة

كيف نتجنب التسمم بالسولانين :

يعد تجنب التسمم بالسولانين أمراً بسيطاً للغاية فما عليك
سوى تجنب شراء واستهلاك حبات البطاطس التي تظهر
على قشرتها اللون الأخضر مهما كانت درجة هذا اللون
بسيطة كما أن تقشير البطاطس يخلصنا من ( 30 – 80 )%
من السولانين إذا كان موجوداً ، و يعمل القلي على درجات
حرارة عالية فوق ( 170 ) م على تخريب هذه المادة ،
و إبطال سميتها إلا أن اختيار حبات البطاطس التي لا يظهر
على قشرتها أي لون أخضر بالطبع يبقى أهم وأول خطوة للوقاية من هذا السم .

ما هو السولانين وهل يعد ساما؟

هو عبارة عن جلايكو ألكالويد مر الطعم وسام، C45H73NO15،يشتق من براعم البطاطا والطماطمولديه خصائص ناركوتية والتي استغلت سابقا لعلاج الصرع.يصنع من الألكالويد سولانيدين ومن الكاربوهيدرات(الجلايكو) وسلسلة جانبية.أنظر إلى التركيب في الأسفل


سولانين ألفا

تركيب السولانين:الأزرق الهيكل الخلفي للسولانيدين(تركيب الألكالويد)،الأحمر:بقايا الكاربوهيدرات.
 
يتشكل طبيعيا في أي جزء في النبات بما فيها الأوراق والفاكهة والدرنات.يعد ساما حتى عند الكميات القليلة منه.للسولانين خصائص مقاومة للفطريات وللحشرات ،ويعد واحدا من عوامل الدفاع الموجودة في النباتات.تصنع البطاطا طبيعيا السولانين والكاكونين وهو عبارة عن جلايكوألكالويد ،كالية دفاع ضد الحشرات والامراض والحيوانات المفترسة.أوراق البطاطا وجذوعها غنية بشكل طبيعي بالجلايكوألكالويدات.
يتم اختبار أصناف البطاطا التجارية لمحتواها من السولانين واغلبها يحتوي على كمية اقل من0.2 ملغ/غرام.من ناحية أخرى فإن البطاطا التي تتعرض للضوء والتي تبدا بالاخضرار يمكن أن تحتوي على تراكيز حوالي 1ملغرام/غرام او أكثر.في هذه الظروف يمكن لحبة بطاطا غير مقشرة أن تتسبب بجرعة خطرة.
سمية السولانين
تظهر سمية السولانين بشكل رئيسي باعتلالات هضمية وعصبية.تتضمن الأعراض: الغثيان والاسهال والاستفراغ وتشنج المعدة وحرقة الحنجرة والصداع والدوخة.الهلوسة وفقدان الاحساس والشلل والحمى واليرقان وتوسع البؤبؤ وانخفاض الحرارة جميعا اعراض مسجلة في الحالات الحادة من المرض.
أما الكميات الكبيرة من السولانين فيمكن أن تسبب الموت.تقترح احدى الدراسات أن الجرعات من 2 إلى 5 ملغرام لكل كيلوغرام من وزن الجسم يمكن ان يسبب أعراض سمية:أما الجرعات بين 3إلى 6 ملغرام لكل كيلوغرام من وزن الجسم يمكن أن تكون قاتلة.
تحدث الأعراض عادة من 8 إلى 12 ساعة بعد الالتهام،لكن يمكنها أن تحدث بسرعة تصل إلى 30 دقيقة بعد تناول أطعمة محتوية على تراكيز عالية من السولانين.
يحدث أغلب السولانين عند القشور أو مباشرة تحت قشور البطاطا.وجد بان البطاطا المقشرة تحتوي على 30-80% من السولانين أقل من تلك الغير مقشرة.ويجب ان يتم تقشير البطاطا الخضراء دائما إذا أردنا استخدامها بشكل كامل.يتواجد السولانين والكاكونين في البراعم أيضا.
القلي المتوغل عند درجة حرارة 170 سيلوسي فعال في التقليل من مستويات الجلاليكو ألكالويد،الغلي غير فعال أما المايكرويف فيعد فعالا نوعا ما.

Solanaceae

From Wikipedia, the free encyclopedia
Jump to: navigation, search
"Nightshade" redirects here. For other uses, see Nightshade (disambiguation).
Solanaceae is a family of flowering plants that includes a number of important agricultural crops. Many species are toxic plants. The name of the family comes from the Latin Solanum "the nightshade plant", but the further etymology of that word is unclear. Most likely, the name comes from the perceived resemblance that some of the flowers bear to the sun and its rays, and in fact a species of Solanum (Solanum nigrum) is known as the sunberry. Alternatively, it has been suggested the name originates from the Latin verb solari, meaning "to soothe". This presumably refers to soothing pharmacological properties of some of the psychoactive species of the family.
The family is also informally known as the nightshade - or potato family. The family includes Datura, Mandragora (mandrake), Atropa belladonna (deadly nightshade), Lycium barbarum (Wolfberry), Physalis philadelphica (Tomatillo) , Physalis peruviana (Cape gooseberry flower), Capsicum (chili pepper, bell pepper), Solanum (potato, tomato, eggplant), Nicotiana (tobacco), and Petunia. With the exception of tobacco (Nicotianoideae) and petunia (Petunioideae), most of the economically important genera are contained in the sub-family Solanoideae.
Many members of the Solanaceae family are used by humans, and are important sources of food, spice and medicine. However, Solanaceae species are often rich in alkaloids whose toxicity to humans and animals ranges from mildly irritating to fatal in small quantities.

[edit] Description

Plants are herbs, shrubs, trees, or sometimes vines. The flowers are usually actinomorphic. Flower shapes are typically rotate (radiately spreading in one plane with a short tube) or tubular (elongated cylindrical tube), with 4-5 petals that are usually fused. Leaves are alternate. The fruit has axile placentation and is a berry as in the case of the tomato or wolfberry, or a dehiscent capsule as in Datura. The seeds are usually round and flat, about 2–4 millimetres (0.079–0.16 in) in diameter. The stamens are epipetalous and are typically present in multiples of 4 or 5, most commonly four or eight. The ovary is superior.[2]

[edit] Genetics

Question book-new.svg This unreferenced section requires citations to ensure verifiability.
Most Solanaceae members have 12 chromosomes, a number that has increased due to polyploidy. Wild potatoes, of which there are approximately 200, are predominantly diploid (2 * 12 = 24 chromosomes) but triploid (3 * 12 =36 chromosomes), tetraploid (4 * 12 = 48 chromosomes), pentaploid (5 * 12 = 60) and even hexaploid (6 * 12 = 72 chromosome) species or populations exist. The cultivated species Solanum tuberosum has 4 * 12 = 48 chromosomes. Some capsicum species have 2 * 12 = 24 chromosomes, while others have 26 chromosomes.

[edit] Alkaloids

Solanaceae is known for having a diverse range of alkaloids. As far as humans are concerned, these alkaloids can be desirable, toxic, or both.
One of the most important groups of these compounds is called the tropane alkaloids. The term "tropane" comes from a genus in which they are found, Atropa (the belladonna genus). Atropa is named after the Greek Fate, Atropos, who cut the thread of life. This nomenclature reflects its toxicity and lethality.
Tropane alkaloids are also found in the Datura, Mandragora, and Brugmansia genera, as well as many others in the Solanaceae family.[3] Chemically, the molecules of these compounds have a characteristic bicyclic structure and include atropine, scopolamine, and hyoscyamine. Pharmacologically, they are the most powerful known anticholinergics in existence, meaning they inhibit the neurological signals transmitted by the endogenous neurotransmitter, acetylcholine. Symptoms of overdose may include dry mouth, dilated pupils, ataxia, urinary retention, hallucinations, convulsions, coma, and death.
Despite the extreme toxicity of the tropanes, they are useful drugs when administered in extremely small dosages. They can reverse cholinergic poisoning, which can be caused by overexposure to pesticides and chemical warfare agents such as sarin and VX. More commonly, they can halt many types of allergic reactions. Atropine, a commonly used ophthalmological agent, dilates the pupils and thus facilitates examination of the interior of the eye. Scopolamine is used as an antiemetic against motion sickness or for people receiving chemotherapy. Atropine has a stimulant effect on the central nervous system and heart, whereas scopolamine has a sedative effect.
An infamous alkaloid derived from Solanaceae is nicotine. Like the tropanes, its pharmacology acts on cholinergic neurons, but with the opposite effect (it is an agonist as opposed to an antagonist). It has a higher specificity for nicotinic acetylcholine receptors than other ACh proteins. Nicotine occurs naturally in the Nicotiana or Tobacco genus.
Another class of toxic substances found in this family are the glycoalkaloids, for example solanine which has occasionally been responsible for poisonings in people who ate berries from species such as Solanum nigrum or Solanum dulcamara, or green potatoes.[4][5]
The chemical in chili peppers responsible for the burning sensation is capsaicin. Capsaicin affects only mammals, not birds. Pepper seeds can always survive the digestive tract of birds; their fruit becomes brightly colored once its seeds are mature enough to germinate thereby attracting the attention of birds who then distribute the seeds. Capsaicin extract is used to make pepper spray, a useful deterrent against aggressive mammals.

The Solanaceae Family
The Solanaceae family provides some of the world's most popular vegetables. Potatoes and tomatoes are among the top in the list of most produced vegetables in the U.S.1
Given their current popularity, it's hard to believe tomatoes were once thought to be poisonous.2 Tomatoes don't keep well if refrigerated, so gardeners await the first ripe tomato with anticipation. This vine ripened tomato is totally unlike the tasteless irradiated version of the tomato found in stores during the winter. Once you've tried a sun-warmed, vine-ripened tomato, you'll be among the group waiting for the first one next year!
Latin name Common name
Genus species
Capsicum annuum sweet pepper, chili pepper
Capsicum chinensis habanero, hot paper lantern, and Caribbean red hot peppers
Physalis ixocarpa tomatillo
Physalis pruinosa husk cherry
Solanum lycopersicum tomato
Solanum melanocerasum garden huckleberry
Solanum melongena eggplant
Solanum tuberosum potato
Culture:
All members of this family need full sun. They all prosper in well-drained soil with lots of organic matter.
All Solanaceae family members except for potatoes should be started as seedlings. Peppers and eggplants can be started 8-10 weeks before the last frost, depending on variety. Hot peppers, especially the chinensis species, take a while to germinate and grow into a nice size for transplanting so these can be started up to 10 weeks before the last frost. Tomatillos and tomatoes grow fairly quickly, so these can be started 6 weeks before the last frost. Potatoes are planted in seed potato form (very small potatoes or potato pieces) in early or mid spring.
With the exception of potatoes, Solanaceae family members need warm weather. Transplant seedlings after all danger of frost has passed and the weather has settled into warmer days. Mulch when the soil is warm to ensure even soil moisture and keep down weeds.
For taller peppers, tall tomatillo varieties, and tomatoes set up a support system when the plants are put in. Cages and posts work well. Whatever method you choose, make sure it will be large and sturdy enough to support the plants when they are mature. If in doubt, err on the side of sturdier construction.
Potato plants should be "hilled up" as they grow. This is most often done with soil but can also be accomplished with old hay. If using the latter, be generous. Potatoes exposed to sun will develop a green tinge which is not edible.
Eliminate moisture stress on all of these vegetables by being consistent with watering practices. Mulching will aid in this and is imperative with potatoes.
Pests and Diseases:
Pests and diseases seem to like this family as much as people do. Potential pests include aphids, cabbage loopers, Colorado potato beetles, corn earworms, cucumber beetles, European corn borers, leafhoppers, leafminers, potato tuber worms, tomato hornworms, pepper maggots, nematodes, and flea beetles.3 The major pests are described below.
Colorado potato beetles are the worst potato pest. The adults are the size of lady bugs and are yellow with black stripes. The larvae are red grubs with two rows of black dots and a black head. Yellow eggs are laid on the underside of leaves. Controls include covering the bed with a row cover as soon as its planted, hand picking of insects and eggs, and/or spraying the larvae with Bt. While potatoes are their favorite vegetable, they will also attack other members of the family.
Flea beetles are the bane of eggplants. These beetles are small and recognized because they jump when disturbed. They will leave a shot-hole pattern in the leaves weaken the plants considerably. A floating row cover installed at planting time is an effective control. Wood ashes are reported to repel them.4
Tomato hormworms are large (up to 4" long), green with white stripes and have a "horn" on the back end. They feed on the leaves of tomatoes and other members of the family. They are easily removed by hand or killed by spraying Bt. (Bt works for other worms and caterpillars as well.) Hornworms have natural predators, such as the brachonid wasp. Worms with rows of white eggs should be left to provide a new generation of brachonid wasps.
Spotted and striped cucumber beetles eat plant tissue but their greatest threat is their ability to carry bacterial diseases. The larvae eat roots. Crop rotation will alleviate problems with the larvae. Row covers can protect plants while they are young.
Potential diseases include black leg, early blight, internal blackspot, lat blight, mosaic, rhizoctonia, ring rot, scab, verticillium wilt, anthracnose, bacterial wilt, blossom drop, blossom end rot, bacterial canker, and fruit rot.5
Crop rotations of 4 years for members of the family are strongly recommended as a key to disease prevention. Consistent watering is also an effective disease deterrent for blossom drop and blossom end rot. In conjunction with adequate watering, blossom end rot can be prevented by ensuring adequate calcium. Test your bed prior to planting and add lime if necessary to achieve a pH of 6.5-7.0. Whenever possible, plant disease resistant varieties. To prevent phytopthora and bacterial spot, avoid watering the leaves of plants.
Harvest and Curing:
With the exception of potatoes, pick fruit promptly when ripe to keep production at optimum levels. Discard any fruit that is blemished or has fallen off the plants. When harvesting eggplant, use clippers to cut the stems. Do not pull the fruit off the plant, as part of the plant will probably be removed with it.
Potato harvest can begin 8 weeks after planting with "new" potatoes. The mature crop is harvested 100-115 days after planting. When the foliage dies down, the entire bed can be harvested by gently lifting the plants with a garden fork. If the potatoes were hilled up with straw, the plants can be pulled up and most of the potatoes will come up with it. Cure by allowing the skins to dry. Store in a cool, dark place.
Seed saving:
The flowers of this family are self pollinating but attractive to many insects. Different varieties within a species can easily cross so isolation, blossom baging with polyspun fabric, or caging is recommended.6
Potatoes are most often propagated from seed potatoes or pieces of large potatoes. The seeds for other members of the family are harvested from ripe fruit. The fruit is cut into pieces and put in a bucket with water. Good seeds will sink and fruit pieces and non-viable seeds will float to the top. All floating matter is discarded and more water is added until all that is left is the good seeds at the bottom. Strain the seeds and allow to dry, stirring regularly to prevent rot during the drying process.7
Tomato seeds are fermented to kill seed-borne diseases and to discard the gelatinous sack that covers the seeds. This is done by mashing the ripe fruit, placing it in a bucket, and adding a cup of water per cup of mashed fruit. Allow it to ferment for three days, stirring twice a day. This will smell as bad as it sounds! Find a location for the bucket accordingly, keeping in mind that some animals like things that smell foul. When mold completely covers the surface of the bucket or when bubbles are seen rising to the surface, double the mixture size by adding water. Stir well so the viable seeds will sink and pour off the rest of the mix, adding water as necessary. Put seeds through a strainer and dry.8

SOLANACEAE - The Potato Family This is a large Family with around 2000-3000 species in 90 different genera, found in most temperate and tropical regions, with a large number coming from Australia and Central and South America. It is a family mainly of herbs, with a few shrubs and trees, and contains many of our most well-known food plants, including Potatoes, Tomatoes, Aubergines and Peppers. It also contains many popular garden ornamental plants, including Petunias, Browallia and Salpiglossis. There are several poisonous species, including Deadly Nightshade (Atropa belladonna), Henbane (Hyoscyamus niger) and Thorn Apple (Datura stramonium), and the family also contains the important economic plant, Tobacco (Nicotiana tabacum), which contains the highly toxic alkaloid nicotine.
Characteristics of this Plant Family:
Leaves, Stem & Roots ~ Members of this Family are often climbers or at least scrambling plants, often with hairy stems and leaves. The leaves are variable, and may be entire or dissected, without stipules, and are usually alternate. The calyx has five parts, which may be joined, and it often remains and enlarges around the fruit, as in Cape Gooseberry (Physalis) or the Shoo-Fly Plant (Nicandra).
Flowers ~ The flowers have five petals and are generally regular in shape. They may be round and flat or star-shaped, but are often bell shaped or tubular. They usually occur in groups in the leaf axils, although they may be solitary. There are five stamens attached to the corolla tube.
Seeds ~ The ovary is superior (inside the flower), and the fruit is either a berry or a capsule, often containing many light brown disc-shaped seeds.
Members of this Family usually have:
Regular flowers with five petals
Alternate leaves
Five stamens attached to the corolla tube
Superior ovary containing many yellowish disc-shaped seeds

*** Many parts of many members of this Plant Family are POISONOUS ***

Solanum, the nightshades, horsenettles and relatives, are a large and diverse genus of annual and perennial plants. They grow as forbs, vines, subshrubs, shrubs, and small trees, and often have attractive fruit and flowers. Many formerly independent genera like Lycopersicon (the tomatoes) or Cyphomandra are included in Solanum as subgenera or sections today. Thus, the genus nowadays contains roughly 1,500-2,000 species. The species usually most commonly called nightshade in North America and England is Solanum dulcamara, also called bittersweet and woody nightshade. Its foliage and egg-shaped red berries are poisonous, the active principle being solanine, which can cause convulsions and death if taken in large doses. The black nightshade (S. nigrum) is also generally considered poisonous, but its fully ripened fruit and foliage are cooked and eaten in some areas.
The generic name was first used by Pliny the Elder (23-79) for a plant also known as strychnos, most likely S. nigrum. Its derivation is uncertain, possibly stemming from the Latin word sol, meaning "sun," referring to its status as a plant of the sun. Another possibility is that the root was solare, meaning "to soothe," or solamen, meaning "a comfort," which would refer to the soothing effects of the plant upon ingestion.[2]
Most parts of the plants, especially the green parts and unripe fruit, are poisonous to humans (although not necessarily to other animals), but many species in the genus bear some edible parts, such as fruits, leaves, or tubers. Several species are cultivated, including three globally important food crops:
Other species are significant food crops regionally, such as Ethiopian Eggplant and gilo (S. aethiopicum), naranjilla or lulo (S. quitoense), Turkey Berry (S. torvum), pepino (S. muricatum), or the "bush tomatoes" (several Australian species).
While most medical relevance of Solanum is due to poisonings which are not uncommon and may be fatal, several species are locally used in folk medicine, particularly by native peoples who have long employed them. Giant Devil's-fig (S. chrysotrichum) has been shown to be an effective treatment for seborrhoeic dermatitis in a scientific study.[3]
Solanum species are used as food plants by the larvae of some Lepidoptera species (butterflies and moths) - see list of Lepidoptera that feed on Solanum.

The genus was established by Carl Linnaeus in 1753.[4] Its subdivision has always been problematic, but slowly some sort of consensus is being achieved.
The following list is a provisional lineup of the genus' traditional subdivisions, together with some notable species.[4] Many of the subgenera and sections might not be valid; they are used here provisionally as the phylogeny of this genus is not fully resolved yet and many species have not been reevaluated.
Cladistic analyses of DNA sequence data suggests that the present subdivisions and rankings are largely invalid. Far more subgenera would seem to warrant recognition, with Leptostemonum being the only one that can at present be clearly subdivided into sections. Notably, it includes as a major lineage several members of the traditional sections Cyphomandropsis and the old genus Cyphomandra.[5]

Solanaceae

Solanales. The Solanaceae are herbs, shrubs, or trees comprising about 85 genera and 2,800 species that are frequently lianous or creeping. The leaves are alternate, usually simple, and lack stipules. The flowers are bisexual and actinomorphic or only slightly zygomorphic. The perianth and androecium whorls generally are isomerous and usually are 5- or sometimes 4- or 6-merous. The calyx is synsepalous, ranging from tubular to deeply cleft. The corolla is sympetalous and ranges from forms with a short tube and rather long, reflexed lobes to forms with a long tube and short lobes. The stamens are distinct, alternating with the lobes of the corolla, and adnate to the corolla tube or perigynous zone. The gynoecium consists of a single compound pistil of 2 carpels, a single style, and a superior ovary with 2 or rarely more locules by false partitioning, each with nearly always numerous axile ovules. A nectary disk is generally present around the base of the ovary. The fruit is a berry or septicidal capsule.

Quotations
And shrieks, like mandrakes’, torn out of the earth,
That living mortals, hearing them, go mad
(‘Romeo and Juliet’, iv.,3)
Atropa, too, that, as the beldams say,
Shows her black fruit to tempt and to betray
(Charlotte Smith, quoted by Ann Pratt, ‘Wild Flowers’ (1857))
The pipe, with solemn interposing puff,
Makes half a sentence at a time enough
(William Cowper, ‘Tobacco’)
When potatoes, leaves, or haulms are green,
To livestock must they ne’er be gi’en
(ancient anon, re. solanine poisoning.)
