摘要
金盏菊种子萌发过程中凡下胚轴生长较快、伸长较长的个体均形成壮苗。下胚轴大部分区段同时具有根、茎初生结构的特征。过渡区位于下胚轴上部。子叶迹与上胚轴维管组织雏形在子叶节区发生分离。
In the Process of Calenaula Officinalis Linn.seed germination,all those seedlings will be-come strong ones that hypocotyls are long and grow fast.Most portion of hypocotyl has the char-acteristic of the primary structures of its root and stem.Transition zone is at the upper part ofhypocoty1.The cotyledon trace and microcosm of epicotyl vascular tissue separate in cotyledonarynode zone.
