中文摘要：

在采用不同药剂处理破除嵩草种子休眠的基础上，利用高效液相色谱测定嵩草种子中脱落酸含量变化，探讨影响嵩草种子休眠的因素。结果表明：40％的NaOH处理使矮生嵩草及高山嵩草种子的发芽率达到最高，分别为56．00％和46．00％。处理前种子中的脱落酸含量分别为3．451和4．571μg／g，处理后脱落酸含量分别为1．225和1．813μ／g，分别下降了64．50％和60．34%。

英文摘要：

Germination tests have been carried out with different treatments on the seeds of Kobresia Willd and the quantity of abscisic acid before and after the treatment was determined by a HPLC method. The results showed that the germination rates of both Kobresia humilis and Kobresia pygrnaea reached the highest with a treatment of 40% NaOH, which was separately 56. 00% and 46.00%. The abscisic acid in the seeds was separately 3. 451 μg/g and 4. 571 μg/g before the treatment and after the treatment was separately 1. 225 μg/g and 1. 813 μg/g, which decreased separately by 64.50% and 60.34%.
