摘　　要：本试验结果表明 ,雌雄配子体形成过程和程序与前人结论相一致 ,但发现 :1 )尽管雌雄蕊同时形成 ,但在雌雄配子形成不同步的情况下 ,花粉和胚囊中的大量淀粉却能同时充实 ,并且同时成熟等待受精。 2 )大孢子母细胞形成比小孢子母细胞迟 0 .7～ 0 .8片展叶 ;雌配子体形成比雄配子体迟 0 .5～ 0 .6片展叶。 3)雌雄两性细胞发育特点不同 ,雄性是小孢子形成快而花粉粒发育慢 ,雌性是大孢子形成慢而胚囊发育快 ,为此在所用时间上 ,花粉粒发育约是小孢子形成的 1 .6倍 ,是胚囊发育的 2 .3倍 ,而大孢子形成约是胚囊发育的 2 .2倍 ,约是小孢子形成的 1 .4倍。This test showed: the developing process of female and male gametophytes is identical with the former resolution. While what we found as follows:1) Although stamen and pistil formed at the same time, the pollen grain and embryosac could be filled with a great quantity of starch and would be mature for fertilization under the condition of female and male gametophyte forming insimultaneously, 2)megaspore mother cell, megaspore, female gametophyte formed respectively more lately than microspore mother cell, microspore and male gametophyte by 0.5 ～0.6,0.7～0.8 and 0.5～0.6 unfolding leaves; 3) for the male the mircropore formed fast while the pellon grains developed slowly and for the female the megaspore grew slowly while the embryo developed fast.
