摘要
以多小叶大豆品系牡5796-3为材料,设置在不同生育时期摘除多的2片小叶,共5个处理,研究了多小叶源对大豆光合特性和产量的影响。结果表明:各处理R6期的叶绿素含量差异不显著;全生育期不摘叶处理的光合速率、单株叶面积、叶面积指数、单株荚数、单株粒数和百粒重均明显高于全生育期摘除多的2片叶的对照处理,因此,产量明显高于对照。总之,由于多小叶大豆品系具有良好的农艺性状和产量表现,可做育种亲本加以利用。
To investigate the effect of leaf source on photosynthetic characteristics and yield in multifoliolate soybean,the multifoliolate soybean strain Mu 5796-3 was selected as material and five treatments of removing the extra two leaflets at different growth stages were set in this study.The results showed that the difference of chlorophyll content at R6 stage among treatments didn＇t reach significant level.The net photosynthetic rate（Pn）,leaf area per plant and leaf area index（LAI） of not removing the extra leaflets（T5） were significantly higher than those removing the extra leaflet at whole growth periods（CK）.Thereby leading to the increase of seed number per plant and 100-seed weight,increased seed yield of T5 treatment.Considering the better agronomic and yield performance of soybean strain Mu 5796-3,it could be used as parent in soybean breeding.
