摘　　要：耐阴黑豆的光合产物合成和积累多，每天运往豆荚、豆粒的干物质明显高于凤交６６－１２和京黄３号，它的ＣＯ２补偿点低，花荚脱落率低，产量也高。同时，经Ｎｏｒｔｈｅｒｎ斑点杂交测定，它的硝酸还原酶基因，二磷酸核酮糖羧化酶小亚基基因及３－磷酸甘油醛脱氢酶基因等在花荚期的叶片中表达能力均高于对照品种京黄３号，特别是在干旱和阴湿的逆境条件下，它们的高效表达更为突出。上述的特性表明，耐阴黑豆是一个特性优良的大豆新种质。In Shade-enduring black soybean which synthesizes and accumulates more photosynthetic products, dry matter transported to both pod and seed per day is remarkably more than in other cultivars such as Fengjiao 66-12 and Jinghuang 3.In addition to its lower CO 2 compensation point and lower abscission rate of flower and pod, its yield is higher. Dot blot demonstrated that in this cultivar, the ability to express of nitrate reductase gene, glyceraldehyde-3 phosophate dehydrogenase gene and Rubisco small subunit gene in the leaf during flowering and podding is all higher than that in other cultivars. The high-efficient expressing is especially eminent under dry or shade and wet condition. All these indicate that Shade-enduring black soybean is a germplasm with excellent characteristics.
