This family of plants has a wide variety of economic uses, most importantly as a<br />
vegetable crop. Most cultivated edible varieties <strong>in</strong>clud<strong>in</strong>g Brussels sprouts, cabbage,<br />
broccoli, and cauliflower were developed by plant breeders from a s<strong>in</strong>gle species,<br />
Brassica oleracea. Many crucifers are used as condiments and garnishes such as mustard<br />
and cress. Important crops are propagated from seed. Only m<strong>in</strong>or crops such as<br />
watercress, horseradish and sea kale are vegetatively propagated. Although desired by the<br />
market <strong>in</strong> the case of crops such as mustard, radish and horseradish, crucifers may also be<br />
responsible for toxic manifestations when used as animal feed or <strong>in</strong> human nutrition.<br />
Recently, some cultivated varieties such as broccoli have been thought to help prevent<br />
cancer. Cruciferous oil seeds rank fifth <strong>in</strong> importance beh<strong>in</strong>d soybeans, cottonseeds,<br />
groundnut and sunflower seed. Animal feeds are provided by cruciferous crops <strong>in</strong> the<br />
form of silage, seed meal, forage crops (grazed <strong>in</strong> the field) and root fodder (used for<br />
w<strong>in</strong>ter feeds).<br />
The Brassicaceae or Cruciferae Family conta<strong>in</strong>s both annual and perennial herbs but<br />
rarely small shrubs. Leaves are usually alternate, exstipulate, with unicellular, simple or<br />
branched hairs. The basic floral structure is highly characteristic and constant, conta<strong>in</strong><strong>in</strong>g<br />
four sepals, four petals, six stamen (four long and two short, a condition called<br />
tetradynamous), and an ovary with two parietal placenta. The form of the cruciferous<br />
flower unites the group more perhaps than any other character. This is always regular,<br />
perfect, and cruciform, especially for the cole crops such as broccoli. The older family<br />
name "Cruciferae" derives from the Maltese cross shape of the four petals. As <strong>in</strong> most of<br />
the crucifers, poll<strong>in</strong>ation is accomplished by nectar secretions <strong>in</strong>to the bases of the<br />
pouched sepals which attracts <strong>in</strong>sects and promotes cross-poll<strong>in</strong>ation; however, selfpoll<strong>in</strong>ation<br />
of the flowers is a frequent occurrence.<br />
C. CUCURBITACEAE FAMILY<br />
The Cucurbitaceae, commonly known as the gourd<br />
or melon family, <strong>in</strong>cludes a number of popular and<br />
important vegetables. The other crops of<br />
Cucurbitaceae are watermelon, summer squash,<br />
w<strong>in</strong>ter squash, and pumpk<strong>in</strong>. Among m<strong>in</strong>or crops are<br />
citron, gherk<strong>in</strong>, and chayote. The last crop is<br />
propagated by large s<strong>in</strong>gle-seeded fruits and is of no<br />
importance to the seed trade. The family is<br />
characterized briefly by the rather vigorous leafy<br />
prostrate v<strong>in</strong>e habit, although some, notably the<br />
summer squash, have bush-type plants. The<br />
<strong>in</strong>florescence and flowers, although dist<strong>in</strong>ct for each<br />
vegetable, are nevertheless similar to each other <strong>in</strong><br />
color, general form, and arrangement of their parts.<br />
The Cucurbitaceae are mostly prostrate or climb<strong>in</strong>g<br />
herbaceous annuals compris<strong>in</strong>g about 90 genera and<br />
700 species that are further characterized by<br />
commonly hav<strong>in</strong>g 5-angled stems and coiled tendrils.<br />
The leaves are alternate and usually palmately 5-<br />
