以两个风信子品种为试验材料,采用石蜡切片技术,对两个品种花芽分化的过程,以及花芽分化期间可溶性糖含量、蛋白质含量和过氧化物酶活性的变化进行了研究。结果表明：1）可溶性糖含量呈逐步上升趋势;2）蛋白质含量在花序原基出现前逐步下降,花芽分化开始时达到最低值,花序分化期回升,小花分化期又下降;3）过氧化物酶活性表现出下降—上升—下降的变化趋势;4）花芽形态分化可分为未分化期、花序原基分化期、花序轴伸长生长期和小花分化期四个时期,完成花芽分化约需60 d。

The changes of total soluble sugar,protein content and peroxidase activity in different periods of the two cultivars of Hyacinthus orientalis are determined;and based on paraffin section technology,the flower bud differentiation process of two cultivars is studied.It is found that the content of soluble sugar shows a gradually rising trend;the protein content drops gradually before the inflorescence anlage,achieves the minimum value when the flower bud differentiation starts,rises during the inflorescence idiophase,and drops in the floret idiophase;the POD activity displays the change tendency in which it drops first,rises again and then drops;and the bud form differentiation can be divided into four periods including undifferentiated period,inflorescence anlage differentiation stage,inflorescence axial elongation growth period and floret differentiation stage.The complete bud differentiation process needs about 60 days.
