Brassica spp. / Brassica / 芸薹属植物

  • Introduction
    Brassica is a genus of plants in the cabbage and mustard family (Brassicaceae). The members of the genus are informally known as cruciferous vegetables, cabbages, mustard plants, or simply brassicas. Crops from this genus are sometimes called cole crops—derived from the Latin caulis, denoting the stem or stalk of a plant.
    Brassica juncea is an annual herb of the brassica family. Erect many branches, basal leaves obovate or broadly ovate, apex obtuse, base cuneate; Raceme terminal, flowers yellow; Sepals pale yellow, erect; Petals obovate; Angular fruit linear; Seeds spherical, brown. Flowering from March to May, fruit from May to June. Brassica napus is an annual or biennial herb, 30-50 cm high, powdery, with erect, branched stems and only a few scattered bristles on young leaves. The lower leaves are lobed, 5-25 cm long, 2-6 cm wide, the apical lobes ovate, 7-9 cm long, the apex rounded, the base nearly truncated, the margins obtuse, the lateral lobes about 2 pairs, ovate, 1.5-2.5 cm long, the petiole 2.5-6 cm long, with lobes at the base, the middle and upper stems and leaves gradually change from oblong elliptic to lanceolate, the base heart-shaped, holding the stem. Brassica oleracea has a well-developed root system. The main root system is distributed in a 30 cm tillage layer. During the vegetative growth period, the stem is shorter and shrinking, the axillary buds on the stem do not germinate, and the plant height is 40-90 cm. Cotyledons opposite, 2, inverted heart-shaped. The true leaves are green, obovate, with white powder on the surface, the leaves are 13-30 cm long, 8-12 cm wide, and the petioles are 5-15 cm long. Brassica rapa roots are fleshy, spherical, oblate or oblong in shape, with a white, yellow or red outer skin. Roots are white or yellow in texture, and have no spicy taste. The stem is erect, branched, slightly hairy at the lower part, and hairless at the upper part. Basal leaves with large feathered or compound heads, 20-34 cm long, with large apical lobes or leaflets, wavy or shallowly lobed edges, about 5 pairs of lateral lobes or leaflets, gradually decreasing downwards, with scattered prickly hairs.
