荚用菜豆的荚果是否老化(背腹两缝线处是否明显地出现纤维束),以及何时开始老化,这是个重要经济性状,与菜豆品质关系甚大。本文作者采用同一个品种分期播种和在同一地点播种多个品种的反复比较试验法,以及通过不同类型之间的杂交法,查明了供试各品种在老化性状上的固有特性和它们对外界环境的反应,并提出了克服过早老化的措施。 Whether or not the pods of legume beans are aged (whether fiber bundles are evident at the two sutures in the dorsal horn) and when they begin to age is an important economic trait that has a strong correlation with the quality of kidney bean. In this paper, the authors used the repeated comparison test method of sowing the same variety in multiple stages and sowing multiple varieties in the same place, and through the hybridization method between different types, the inherent characteristics of the tested varieties in the aging traits and their effects on the outside world Environmental response and proposed measures to overcome premature aging.
