摘　　要：在大田条件下,以2对不同叶型近等位基因系大豆品系A31和6059为材料,于始花期叶面喷施不同浓度的多效唑来研究不同叶型大豆品系对多效唑的反应。结果表明:始花期叶面喷施不同浓度的多效唑对大豆有显著的增产作用,同时还改善了叶片的生理功能和产量性状。此外,籽粒蛋白质含量得到了提高,脂肪含量降低。不同叶型品系对多效唑的反应不同,表现为圆叶品系的增产效果好于尖叶品系。Two pairs of soybean near-isolines varities with different leaflet shapes（A31 and 6059） were used as experimental materials to study the responses of spraying various concentrations paclobutrazol（MET） at initial blooming stage.The results showed that MET could significantly increase yield,and the function of leaf physiological and yield traits were improved.Besides,it had positive effect on seed protein content,and the oil content was decreased.Different leaflet shape lines had different responses to MET,the effect of MET on yield of round leaflet line was greater than that of narrow line.
