摘要
唐菖蒲６ 个切花品种花序生长发育与叶数的增加呈特定的关系， 在２ ～３ 叶期花序分化开始后， 首先是小花数迅速增加， 至５ 叶期停止增加， 而花茎开始迅速伸长生长， 单个小花生长发育加快， 同时已分化的小花从花序顶端开始发生不同程度的败育， 导致切花的每穗花数降低。
The growth and development of inflorescences of Gladiolus were studied with 6 cultivars.Flower bud initiation began at 2-3 leaf stage,and the increase of floret number continued until 5 leaf stage.From then the rachis extended rapidly,and the development of floret accelerated.At the same time some top florets might abort and therefore it limited the total number of florets on each inflorescence.
