摘要
目的:为适时开展白及种子成苗技术提供技术支撑。方法:采用沙藏、自然贮藏、低温干藏方法分别贮藏白及种子120、150、180 d常规种子皿内发芽法测定萌发率,SSR法比较差异性。结果:白及种子有胚率(84.9±4.7)%、新鲜种子萌发率(92.1±2.1)%;沙藏、自然贮藏、低温干藏种子120、150、180 d的平均萌发率分别为(89.3±2.7)%、(77.4±3.3)%、(68.9±2.7)%,相互间呈显著或极显著差异;种子贮藏120、150、180 d时,三种方法的平均萌发率分别为(81.7±8.0)%、(78.5±7.9)%、(75.7±8.5)%,其中贮藏120 d与180 d的萌发率呈显著差异;新鲜与沙藏120 d白及种子的萌发率无显著差异。结论:沙藏白及种子的萌发效果好,贮藏180 d仍有较高萌发率。
Objective： Exploring seed storage method to offer a technological support for the seedling development of Bletilla striata.Methods： Bletilla striata seeds were stored by means of sand storage,nature storage and low temperature storage for 120,150 and 180 d respectively.The germination rates were measured with methods of seed germination on the Petri dish and difference of rates was compared by means of the SSR method.Results：The embryo rate of Bletilla striata seeds was（84.9±4.7）%;the germination rate of fresh seeds was（92.1±2.1）%;the germination rates of seeds treated by sand storage,nature storage and low temperature storage for 120,150 and 180 d were（89.3±2.7）%,（77.4±3.3）%,（68.9±2.7）% respectively and they showed significant difference or extreme significant difference one another.When seeds stored 120,150 and 180 d,germination rates of seeds treated with three methods were（81.7±8.0）%,（78.5±7.9）%,（75.7±8.5）% respectively,and in these three storage times,germination rates of seeds stored 120 d and 180 d showed significant difference.In addition,there was no significant difference between germination rates of fresh seeds and sand storage seeds stored 120 d.Conclusion：The effect of germination of seeds stored with sand was good,and germination rate was high steal after 180 d.
