蓝花楹开花特性及其花器官构造特征观察

Observation on flowering habit and floral organ structural characterization of Jacaranda mimosifolia

以生长在四川省成都市温江区内两个不同地点的蓝花楹为材料,对其开花特性及花器官特征进行调查。结果表明:蓝花楹在温江地区存在一年两花现象,即5～6月为花期Ⅰ,8～10月为花期Ⅱ,花期Ⅰ的花量大于花期Ⅱ。同时,对蓝花楹的花序和花器官构造进行了观察与描述,旨在为今后蓝花楹在园林植物上的应用提供依据。

Taken two types of Jacaranda mimosifolia which grew in two different regions in Wenjiang district of Chengdu as materil, this paper observed the flowering habits and floral organ structural characteristics of Jacaranda mimosifolia.
