菜用大豆种质资源遮光胁迫下的耐阴性研究

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、单株多粒英、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、标准英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：13本菜用大豆、浙4603、08YC-1、辽00139．1、86C-41、H0346。...

Vegetable soybean; Shading stress; Agronomic traits; Shade-tolerant evaluation
In order to study the effects of vegetable soybean agronomic traits under different shading stress through setting covering double net, single net, and control treatment with 32 vegetable soybean varieties （lines） germplasm, this research surveyed the 12 indicators, in- cluding height, stem diameter, main stem section number, branches number, cell yield and etc. The results showed that, except for plant height, all other 11 indicators, including plot yield, stem diameter, singer pod weight, the plant total pod number, multi-grains pod per plant, total pod number per plant and etc. , declined or decreased. Cell yield was only significantly and positively correlated with plant pod weight on the covered double net; the si
