摘　　要：测定了前期筛选出的22个芽用大豆品种种皮性状和百粒重等物理特性、种子生理特性以及芽用特性指标,分析了各项物理生理特性指标与芽用特性指标的相关性。结果显示：所用大豆品种种子百粒重为8.1-22.3 g,种皮亮度值为38.6-55.1,种子与豆芽产出比为1∶5.12-1∶6.95,下胚轴长和下胚轴粗分别为6.60-11.42和0.24-0.32 cm。种皮亮度与单根豆芽质量及豆芽下胚轴粗呈正相关（P〈0.05）;豆芽产出比与种子百粒重呈极显著负相关（P〈0.01）,与种子活力呈极显著正相关（P〈0.01）;豆芽的感官品质与种子吸水量呈显著负相关（P〈0.05）,与豆芽下胚轴长呈显著正相关（P〈0.05）。分析评价推选S-08-93、S-08-97及S-08-145为综合性状较好的芽用大豆品种。Twenty-two soybean varieties which were selected by previous study were used to determine the seed coat traits such as color and weight proportion of seed coat;physical characteristics such as 100-grain weight of seed;physiological characteristics such as the changes of biomass during germination,water absorption and seed vigor;sprouts characteristics such as sprout production,sprout morphological and sensory quality.This article analyzed the seed coat traits and the relationships between the physiological characteristics and the sprouts characteristics.The results showed that the ranges of 100-grain weight were 8.1-22.3 g.The ranges of brightness value were 38.6-55.1.The ranges of seed input-sprout output ratio were 1∶5.12-1∶6.95 and the ranges of hypocotyl length and diameter were 6.60-11.42 and 0.24-0.32 cm respectively.The brightness of seed coat had significant positive correlations with single sprout weight and hypocotyl length（P〈0.05）.The sprouts output ratio had an extremely significant negative correlations with 100-grain weight of seeds（P〈0.01） and an extremely significant positive correlation with seed vigor（P〈0.01）.The sensory quality had a significant negative correlations with the water absorption（P〈0.05） and a significant positive correlation with hypocotyl length（P〈0.05）.The study also selected S-08-93、S-08-97and S-08-145 that were suitable for sprouts production.
