摘要:
为了探索银缕梅稀有频危原因,于1990~1995年连续对其花芽生长和开花习性进行观察.结果表明:银缕梅花芽分化到苞片展开,需经1a时间;苞片展开,雌、雄蕊裸露20d后.雄蕊趋于成熟,雌蕊比雄蕊迟熟5~9d,故为雌雄异熟型.银缕梅坐果率为0~1(2),经人工辅助授粉可明显提高坐果率1倍以上,并能增强种子活力,使种子发芽率上升到85%~90%.
Abstract:
Since the growing trees of Shaniodendron subaequale (Chang) Deng, Wei et Wang were found by the anthors in Yixing in 1988,great attention has been paid to the conservation of this species and studies on its rare and endangerous causes. From 1990 to 1995,observation was done on the growth of flower buds and flowering habit of this plant. It needs 1 a for its flower buds to be differentisted. Its naked stamens become mature in 20 d after bracts spreading and about 5-9 d earlier than pistils,so they are self incompatible. If the plant was self pollinated,the rate of fruit setting and rate of seedling would be very low. Artifirial pollination has been used and could obviously increase the 2 rates.
