北沙参种子发芽和生活力检验方法的研究

目的：确定北沙参种子适宜的发芽和生活力的检验方法。方法：采用不同的发芽床，放置于不同的温度下培养，观察不同条件对北沙参发芽率的影响，确定适宜的发芽条件；采用四唑法（TTC）对北沙参着色率进行检验，设计不同浓度和不同温度的正交试验，通过对不同条件下北沙参染色情况的观察，确定适宜的生活力检验方法。结果：北沙参以25℃，滤纸作为发芽床为适宜发芽条件；以30℃，0．6％TYC浓度，染色时间5h为适宜的生活力检验方法。结论：通过对北沙参发芽和生活力检验方法的研究，为其种子检验规程和质量标准的制定提供依据。

Testing Methods of Germination and Viability of Glehnia littoralis Fr. Schmidt ex Miq. Seed

Objective： To determine the suitable testing methods of germination and viability of Glehnia littoralis Fr. Schmidt ex Miq. seed. Methods： The appropriate seed germination conditions were obtained by testing the influence of the different germination beds and temperatures on the average germination rate. The appropriate testing method of seed viability was found out by observing the effects of different concentration and temperature of TCC on the seed dye rate. Results： The appropriate conditions for seed germination are at 25 ℃ on filter paper. The best testing conditions of seed viability are dying for 5 hours in0. 6% TCC at 30℃ Conclusion： Based on the research of germination conditions and testing method of seed viability, our study offers help for the establishment of testing rules and quality standard of G. littoralis seed.
