Its outcrossing index is 3, self-compatible and sometimes demand for pollinators; its Pollen-ovlue ration is 244.7-2588, facultative xenogamy. Used gravity-glass-slice method to make sure its anemophily mode.
2、沉水樟的杂交指数为3,表明沉水樟繁育系统是自交亲和、有时需要传粉者;其花粉胚珠比为244.7-2588,说明沉水樟是兼性异交:用重力玻片法确定沉水樟是以风媒方式传粉,在沉水樟花期没有传粉昆虫出现,但发现有类似实蝇的蝇出现于花间。
