芽用绿豆品种子粒性状及其豆芽生理特性研究

以21份芽用绿豆品种为材料,研究了种皮色泽、种皮比重等种皮性状、百粒重等物理特性、发芽期间的生物产量变化规律、种子吸水速率等生理特性以及绿豆芽产量、豆芽形态特征和感官品质等芽用特性指标,分析了各项物理生理特性指标与芽用特性指标的相关性。结果表明,芽用绿豆品种的产出比、下胚轴粗和下胚轴长等特性指标范围分别为111.7～143.2、7.21～11.79和0.245～0.353;品种的种皮色泽与绿豆芽生物产量、绿豆芽下胚轴粗及下胚轴长无显著相关,而与品种的百粒重呈显著相关性;百粒重与绿豆芽生物产量呈显著负相关;下胚轴粗与绿豆芽生物产量呈极显著负相关;初步建立了适用于评价绿豆品种芽用特性的指标：豆芽产...

Summary:以21份芽用绿豆品种为材料,研究了种皮色泽、种皮比重等种皮性状、百粒重等物理特性、发芽期间的生物产量变化规律、种子吸水速率等生理特性以及绿豆芽产量、豆芽形态特征和感官品质等芽用特性指标,分析了各项物理生理特性指标与芽用特性指标的相关性。结果表明,芽用绿豆品种的产出比、下胚轴粗和下胚轴长等特性指标范围分别为111.7～143.2、7.21～11.79和0.245～0.353;品种的种皮色泽与绿豆芽生物产量、绿豆芽下胚轴粗及下胚轴长无显著相关,而与品种的百粒重呈显著相关性;百粒重与绿豆芽生物产量呈显著负相关;下胚轴粗与绿豆芽生物产量呈极显著负相关;初步建立了适用于评价绿豆品种芽用特性的指标：豆芽产量、下胚轴粗和下胚轴长,筛选出具有较好芽用特性的绿豆品种MB01、MB07、MB19和MB45。

21 mung bean varieties were used to analyse seed physical characteristics such as seed coat color,seed coat proportion,100-grain weight and seed physiological characteristics such as biological yield variation during germination,water absorption rate,as well as the sprout traits such as mung-bean sprouts yield,morphological characteristics of sprouts and sensory quality of sprouts,This study also analysed the correlation among physical,physiological characteristics and other characteristics of sprouts.The results showed that the range of the indices（sprouts yield,hypocotyl diameter and hypocotyl length） of 21 mung bean materialsas 111.7-143.2,7.21-11.79 and 0.245-0.353,respectively.There was no significant correlation between seed coat color and biological yield,hypocotyl rough,hypocotyl length.There was significant correlation between seed coat color and 100-grain weight.100-grain weight and biological yield had signi
