摘要
苦豆子和披针叶黄华种子形状、颜色、表面状态差异显著,种子健壮度和硬实率很高,含水量都很低且差异不显著;苦豆子种子长度显著大于披针叶黄华,披针叶黄华种子体积质量和千粒质量显著大于苦豆子,两种豆类宽度、厚度和相对密度之间无显著差异;在新鲜干净的两个豆类种子中,硬实种子和非硬实种子同时存在,破除苦豆子和披针叶黄华种子硬实的最佳措施是:90%的H2SO4处理70min和120min;破除硬实的两种豆类种子萌发的物质转化效率达到了77.94%和77.28%,苦豆子和披针叶黄华种子开始萌发时间均为21h,最低萌发需水率分别为151.05%和151.71%,两种种子萌发相对需水较多,苦豆子种子萌发40h达最大发芽值,披针叶黄华种子56h达最大发芽值。
The sharp, color and surface state of Sophora alopecuroides and Thermopsis lanceolata seeds collected from desert edge were researched in laboratory. The results showed that sharp, color, appearance had significant difference. Strong degree and hard seed rate were higher, but the water content was lower. The length of Sophora alopecuroides was larger than that of Thermopsis lanceolata, but the bulk density and TGW of Thermopsis lanceolata seeds were higher than that of Sophora alopecuroides seeds. The width, thickness and bulk density had no significant difference. Hard seed and non-hard seed were all existed together in fresh and pure bean seeds. The best hard seed release methods for Sophora alopecuroides and Thermopsis lanceolata were treating seeds using 90% (v/v) sulfuric acid for 70min and 120min respectively. Sophora alopecuroides and Thermopsis lanceolata seeds had higher materials convert efficiency and reached to 77.94% and77.28%, respectively. Sophora alopecuroides and Thermopsis lanceolata seeds didn’t germinate until 21 h and the lowest water requirement was 151.05% and 151.71%, respectively. They needed more water to germinate. Sophora alopecuroides seeds had a fast germination speed and needed 40 h to reach maximal germination value, and Thermopsis lanceolata needed 56 h to reach that value.
