摘要
该文是对神坡穗花杉种群雌株结种的生态、物候动态观察 ,对其种胚着生部位 ,生长期及其它五年翔实记录的分析结果。神坡穗花杉种群雌株种胚鳞芽苞 ,普遍着生于上年生枝顶或上年结有种子而未成熟的枝顶。种胚鳞芽苞绽裂 ,即可见有梗胚珠多个簇状、对生、上下左右有序排列。种子从当年 3月形成胚珠至翌年6月成熟坠落 ,需经 1 4～ 1 5个月。
The characteristics of ecology, the growth part of the seed and the mature period of the seeding of the female Amemtotaxus aryotaenia population in shenposhan have been researched for five years. The results indicate that the scutellum brood cell of Shenposhan's female Amentotaxus aryotaenia population usually grows at the top of the branches which sprout at the first half of the year or which have unmatured seeds. When the scutellum brood cell split, you can see the cluster of many ovules with stem, they grow in opposite directions and arrange orderly. The mature period of the seeds is about 14～15 months, from March to June of the next year.
