摘要

目的: 考察广金钱草生殖生物学特征

为该药材的资源开发与利用提供参考. 方法: 通过野外观测、室内分析及人工套袋授粉等方法研究广金钱草的繁育系统、开花习性、传粉方式及花粉-胚珠比、杂交指数等生殖生物学特性. 结果: 广金钱草的花为两性花

开花高峰时间9:30~11:00

日开花数量随开花天数的变化近似于正态分布曲线

单花花期1~2 d

种群开花历时45 d;柱头在花即将开放到开后8 h内均具有可授性;花粉-胚珠比8 000±1 225;杂交指数4;人工套袋试验显示以自交为主

异交亲和;传粉昆虫为双翅目的蜂类和膜翅目的蝇类. 结论: 广金钱草繁育系统以自交为主

异交亲和

需要传粉者.

Abstract

Objective: To investigate reproductive biology of Desmodii Styracifolii Herba. Method: Reproductive system

flowering habits

pollination pattern

pollen-ovule ratio (P/O)

out-crossing index (OCI) and other reproductive biology characteristics of Desmodii Styracifolii Herba were measured by field observation

laboratory analysis

artificial bagging pollination and other ways. Result: Flowers of Desmodii Styracifolii Herba was bisexual

blossom peak time was from 9: 30 to 11: 00.Flowering time was about 45 days

and single one was 1 to 2 days.Numbers of daily blossom showed normal distribution patterns.Stigmas had receptivity 1 hour before blossom and after blossom in 8 hours

P/O was 8 000±1 225

OCI was 4.Artificial bagging test showed that breeding system of Desmodii Styracifolii Herba was mainly self-pollination

cross-pollination.Bees of Diptera and flies of Hymenotera were pollinators for Desmodii Styracifolii Herba. Conclusion: Breeding system of Desmodii Styracifolii Herba is mainly self-pollination

cross-pollination and pollinators are needed.
