摘　　要：对荸荠花器构造、开花物候期、开花过程及传粉等方面进行观察研究。试验结果表明,荸荠的花期为6上旬至10月下旬,盛花期为7～9月,单个花穗花期4d左右,从开花到种子成熟约需30d;自然授粉结实率为12.90%,而花穗套袋的自花授粉结实率为1.34%,表明荸荠以异株异花授粉为主,兼具少量的自花授粉。The floral structure, phenophase, process of efflorescence and pollination of Chinese water chestnut [EIeocharis dulcis （Burro. f.） Trin. ex Hensch] were studied. The results showed that the anthesis was between June and October; the full flowering stage was between July and Septemper; and the single inflorescence was about 4 d. It took nearly 30 d from effloresce to maturity of seeds. The seed setting rate under open pollination was 12.90%, but it was t.34% through selfpollination in hag, so it suggested water chestnut gave priority to cross-pollination between different plants.
