摘要
对生长在青海省东部不同地区的黄花铁线莲(Clematisintricate)的种子形态、萌发率进行了研究。证明不同生态条件下的种子的形状存在着差异,但其萌发率却是接近的,种子的萌发率在54%～74%之间。自然环境中越冬的种子萌发率高于刚成熟种子的萌发率。不同温度处理对种子的萌发有一定的影响,最适萌发温度为5℃～25℃变温处理。
It is the first time to study the characters and germination of wild Clematis intricate in He huang area different place, proved that there are many differences in characters and germination among different altitude; the germination rate of Clematis intricate is between 45% and 84%; the germination rate of seeds collected in October is higher than the one collected in march .variable temperature enhance germination rate of Clematis intricate. The study of seeds character and gemination will have high theory and practice meaning on protecting the source of Clematis intricate.
