图1 多室白菜型油菜的花器官和角果表型观察 a~b、c~f、g~j分别代表WT、多室ml4和srb的花器官数目比较; k~l、m~p、q~v分别代表WT、ml4和srb的角果及其横切面显示心皮数目变异; 横切石蜡切片显示在花发育第9~11时期的WT (两心皮, w)、ml4 (3~4心皮, x~y)和srb (2~4心皮, w~y)的雌蕊心皮变异; lc: locule; O: ovule; M: medial region; L: lateral region; 标尺为2 mm (k, m, o, q, s, u)、0.5 mm (l, o, p, r, t, v)和100 μm (w~y)。

Fig. 1 Phenotypic observation of floral and silique morphology of mutilocular B. rapa a-b, c-f, g-j respesent the number of floral organs in WT, ml4 and srb, respectively; k-l, m-p, q-v respesent siliques with different carpel numbers in WT, ml4 and srb, respectively; cross-sections of gynoecia of WT (two carpels, w), ml4 (3-4 carpels, x and y) and srb (2-4 carpels, w to y) at stage 9-11; lc: locule; O: ovule; M: medial region; L: lateral region. Bar = 2 mm (k, m, o, q, s, u), 0.5 mm (l, o, p, r, t, v), and 100 μm (w-y).
