近年来,我们对不同贮藏时间的紫云英种子生命力进行了测定试验,现报道如下。一、材料和方法供试紫云英品种为信阳种。取样为不同年份收获晒干贮藏的种子。以发芽率和发芽势作为判定种子生命力的主要指标。当年收获的种子,9月中旬以前硬粒率特高,用硫酸处理,解除硬粒后投入试验。方法是,将浓硫酸倒入种子,搅拌均匀,持续 In recent years, we tested the vitality of Ziyun Ying seed at different storage time, are reported below. First, the materials and methods for the test of purple Yunying species Xinyang species. Sampling Season the sun-dried stored seeds for different years of harvest. The germination rate and germination potential as the main indicators to determine the vitality of seeds. Seeds harvested the same year, before mid-September the rate of hard grain exceptionally high, with sulfuric acid, remove the hard particles into the test. The method is, the concentrated sulfuric acid into the seeds, stir, and continued
