摘要
西瓜(Citrullus lanatus (Thunb) Mansfeld)为葫芦科西瓜属一年生草质藤本植物。其幼苗同样可分为子叶节区、上胚轴苗区和下胚轴根区,但其子叶节区很长,属顶枝伸长型,并在子叶节区上部形成双韧真中柱雏形,而在子叶节区中部存在管状中柱阶段,子叶多迹。子叶节区—根过渡区极短。
Citrullus lanatus (Thunb) Mansfeld belongs to Cucurbitaceae. Its seedling is also divisded into the cotyledon node zone (C.N.Z.), epicotyl-shoot zone and hypocotyl-root zone, but its C.N.Z.is very long and belongs to telome elongation type.The young form of bicollsteral-eustele is made in the upper part of C. N. Z., the siphonostele exists in the middle part of C. N. Z. The cotyledon has multiple-leaf-trace. The C. N. Z. -root transitional region is very short.
