摘要:
The primary vascular elements originate in the procambia of the single carpel and three stamens of the floret independently and in isolation from the vascular system of the spikelet. The initiation of protophloem elements is earlier in the stamens than in the carpel. The median strand of the carpel differentiates before the two lateral strands. The protoxylem elements are initiated after the protophloem elements are welt differentiated.The differentiation of both protophloem and protoxylem elements is bidirectional in the stamens and in the three strands of the carpel, whereas their differentiation is acropetal in the funicular strand of the carpel.
