摘要
为揭示西藏草地主要毒草茎直黄芪种子的萌发特性,在不同温度(10、15、20、25℃)和不同光照条件下,采用常规纸上发芽法,研究了茎直黄芪种子发芽率(GR)、发芽势(GE)、发芽指数(GI)、胚芽和胚根长度。结果表明,光照可以提高茎直黄芪种子的发芽率,且20℃条件下茎直黄芪种子萌发效果最好。
To reveal the seed germination of Astragalus strictus in Tibetan grassland,the method of germination on conventional paper was adopted at different temperatures(10,15,20,25℃)and under different light conditions.The germination rate(GR),germination energy(GE),germination index(GI),germ and root length of Astragalus strictus were studied.The results showed that light could increase the germination rate of Astragalus strictus seeds.The optimum temperature to Astragalus strictus seed germination was 20℃.
