摘　　要：在昆明气候条件下，研究了不同发芽床及不同处理对纳罗克非洲狗尾草种子发芽率的影响，结果表明：赤霉素溶液浸种，是提高该优良牧草之种子发芽率最经济、最有效的方法；沙培法可作为室内测定非洲狗尾草种子发芽率的标准方法。Seed germination of Setaria sphacelata cv. Narok was studied in Kunming. The comparison of natural germination rates from 3 different germination beds showed that the percentage of germination was the highest in soil culture and higher in sand culture than in paper culture. Seed treated with GA of 200～250 μg/g could obtain the highest rate of germination.
