摘要
】对232份菜豆品种(材料)结荚初期中上部叶片检测表明,叶比重为40~60g/m2,并筛选出小于40g/m2(多为蔓生)和大于60g/m2(多为矮生)叶比重的品种及材料。76份矮生品种叶比重(加权)平均值为53.63g/m2,大于156份蔓生或半蔓生品种的平均值(46.75g/m2)。不同生育期菜豆叶比重变化很大。
Two hundred and thirty two Chinese common bean (Phaseolus vulgaris L.) lines were examined for the changes in Specific Leaf Weight (SLW). The results indicated that SLW distribution ranged primarily from 40 g/m 2 to 60 g/m 2. The lowest (SLW<40 g/m 2) and highest (SLW>60 g/m 2) were presented. Mean SLW value of 76 dwarf cultivars was 53.63 g/m 2, significantly higher than that of 156 trailing ones, 46.75 g/m 2. SLW of c.v. Red Flower changed from 38.35 g/m 2 to 51.28 g/m 2 in different mature groups. Possibility was discussed of effective selection for SLW in increased yield common bean breeding.
