通过对32个菜用大豆品种(系)种质资源设置遮双层网、单层网、对照3种处理比较试验,调查株高、茎粗、主茎节数、分枝数、产量等12个指标,研究不同遮光胁迫对菜用大豆农艺性状的影响。结果表明,遮光胁迫后,除株高增加外,小区产量、茎粗、单株荚重、单株多粒荚、单株总荚数等11个指标均有所下降或减少。遮双层网处理的小区产量只与单株荚重呈极显著正相关关系,单层网处理的小区产量与株高、标准荚长和单株单粒荚呈显著或极显著的相关关系,在对照中小区产量与株高等5个指标呈显著或极显著的相关关系。综合耐阴系数排在前6名的分别是:日本菜用大豆、浙4603、08YC-1、辽00139-1、86C-41、H0346。
Through the comparison of 32 treatments of double layer net, single layer net and comparison three kinds of germplasm resources of 32 vegetable soybean varieties (lines), the plant height, stem diameter, main stem number, branch number, yield and so on were investigated Index to study the effects of different shading stress on the agronomic characters of vegetable soybean. The results showed that after shading, except for the increase of plant height, 11 indicators such as plot yield, stem diameter, pod weight per plant, multiple pods per plant and total pods per plant all decreased or decreased. There was a significant positive correlation between yield per plant and pod weight per plant. Net yield per plant was significantly or extremely significantly correlated with plant height, standard pod length and single pods per plant. There was a significant or significant correlation between yield and plant height in the control plot. Comprehensive resistance to the negative coefficient of the top six are: Japanese food soybean, Zhejiang 4603,08YC-1, Liaoning 00139-1,86C-41, H0346.
