摘要
对53个不同耐阴级别的大豆品种若干性状与耐阴性的关系的研究表明:耐阴性好的株型结构是:有限或亚有限结荚习性、生长习性为直立。株型为收敛或中间型。主茎节数10～13节。结荚节位在3～5节间,结荚高度为10厘米左右。叶柄短而粗,叶片浓绿、窄而厚。抗倒伏的品种耐阴性也强。叶大小、叶形、叶柄与主茎夹角、子叶色、荚大小、发芽率等10余项性状与耐阴性都没有直接的关系。
The result of study on the relation between plant characters of soybean and the shade-endurance conducted in 1990 under the ecological conditions of Guiyang indicated: 1. The good shade-endurable varieties possess following characters: Fruiting habit: determinate or subdeterminate: habit of plant growth: straight: phant trpe: convergent or intermediate: node number of main stem: 10-13; ftuiting nodes at 3-5; fruiting height about 10cm; petiole short and thick; blade narrow and thick, and deep green in colour. 2.The good shade-endurable varieties of soybean showed more resistant to lodging. 3. The blade size and form the angle between petiole and main stem, etc.are not correlating with the shade-endurance of soybean directly.
