Seedless fruits

Seedlessness is an important feature of some fruits of commerce. Commercial cultivars of bananas and pineapples are examples of seedless fruits. Some cultivars of citrus fruits (especially navel oranges and mandarin oranges), table grapes, grapefruit, and watermelons are valued for their seedlessness. In some species, seedlessness is the result of parthenocarpy, where fruits set without fertilization. Parthenocarpic fruit set may or may not require pollination. Most seedless citrus fruits require a pollination stimulus; bananas and pineapples do not. Seedlessness in table grapes results from the abortion of the embryonic plant that is produced by fertilization, a phenomenon known as stenospermocarpy which requires normal pollination and fertilization.

Banana:

Banana is the common name for a fruit and also the herbaceous plants of the genus Musa which produce the commonly eaten fruit - The banana plant is a pseudostem that grows to 6 to 7.6 metres (20-25 feet) tall, growing from a corm - Bananas come in a variety of sizes and colors when ripe, including yellow, purple and red - Bananas and plantains constitute a major staple food crop for millions of people in developing countries - The domestication of bananas took place in southeastern Asia. Many species of wild bananas still occur in New Guinea, Malaysia, Indonesia and the Philippines.

Apple:

The apple is the pomaceous fruit of the apple tree, species Malus domestica in the rose family Rosaceae - The wild ancestor of Malus domestica is Malus sieversii - There are more than 7,500 known cultivars of apples - Like most perennial fruits, apples ordinarily propagate asexually by grafting - Apples are self-incompatible; they must cross-pollinate to develop fruit.

Vegetable:

Many root and non-root vegetables that grow underground can be stored through winter in a root cellar or other similarly cool, dark and dry place to prevent mold, greening and sprouting - Kai-lan, Bok choy, Komatsuna - Amaranth, Bitterleaf, Catsear - Malabar gourd, Marrow, Parwal - Guar, Horse gram, Indian pea
