Aubergine

Description:

The eggplant, aubergine, melongene, brinjal or guinea squash (Solanum melongena) is a plant of the family Solanaceae (also known as the nightshades) and genus Solanum. It bears a fruit of the same name, commonly used in cooking. As a nightshade, it is closely related to the tomato and potato. It is native to India.[1][2] It is a delicate perennial often cultivated as an annual. It grows 40 to 150 cm (16 to 57 in) tall, with large coarsely lobed leaves that are 10 to 20 cm (4–8 in) long and 5 to 10 cm (2–4 in) broad. Semiwild types can grow much larger, to 225 cm (7 ft) with large leaves over 30 cm (12 in) long and 15 cm (6 in) broad. The stem is often spiny. The flowers are white to purple, with a five-lobed corolla and yellow stamens. The fruit is fleshy, has a meaty texture, and is less than 3 cm (1.2 in) in diameter on wild plants, but much larger in cultivated forms. The fruit is botanically classified as a berry and contains numerous small, soft seeds which are edible, but have a bitter taste because they contain nicotinoid alkaloids; this is unsurprising as it is a close relative of tobacco.

Habitat:

In tropical and subtropical climates, eggplant can be sown directly into the garden. Eggplant grown in temperate climates fares better when transplanted into the garden after all danger of frost is passed. Seeds are typically started eight to ten weeks prior to the anticipated frost-free date. Many pests and diseases which afflict other solanaceous plants, such as tomato, pepper (capsicum), and potato, are also troublesome to eggplants. For this reason, it should not be planted in areas previously occupied by its close relatives. Four years should separate successive crops of eggplants. Common North American pests include the potato beetles, flea beetles, aphids, and spider mites. (Adults can be removed by hand, though flea beetles can be especially difficult to control.) Good sanitation and crop rotation practices are extremely important for controlling fungal disease, the most serious of which is Verticillium. Spacing should be 45 cm (18 in.) to 60 cm (24 in.) between plants, depending on cultivar, and 60 cm to 90 cm (24 to 36 in.) between rows, depending on the type of cultivation equipment being used. Mulching will help conserve moisture and prevent weeds and fungal diseases. The flowers are relatively unattractive to bees and the first blossoms often do not set fruit. Hand pollination will improve the set of the first blossoms. Fruits are typically cut from the vine just above the calyx owing to the somewhat woody stems. Flowers are complete, containing both female and male structures, and may be self pollinated or cross pollinated.[7]
