摘 要 ：研究了su_1基因与sh_2,bt_2基因互作对玉米籽粒粒重及营养成份的影响,探讨了这些互作效应对玉米品质育种的利用价值。结果表明:su_1基因与sh_2,bt_2基因互作大幅度降低籽粒百粒重,增加可溶性糖、还原糖和蔗糖含量,降低淀粉含量,增加蛋白质及蛋白质组分中清蛋白、球蛋白和谷蛋白含量,降低醇溶蛋白含量。籽粒氨基酸组成中,天门

Abstract:The effects of interactions of su_1 with sh_2 and bt_2 genes on 11 kernel characterswere studied and their values in maize quality improvement were discussed. The resultswere as follows: The interactions of su_1 with sh_2 and bt_2 genes could reduce 100-kernelweight significantly, increase the conte
