【摘要】 以大豆核不育系ms6和细胞质雄性不育系JLCMS9为材料,研究了9种化控试剂单品及其复合使用对杂交大豆制种产量的影响。结果表明:爱多收可显著提高大豆不育系结荚率和结实率,分别比对照提高28.3%和21.4%,且爱多收具有专一提高母本产量的作用。将不同化控剂复配使用,以含有爱多收为主要成分的复配剂(爱多收+硼酸钠+磷酸二氢钾和蜜蜂引诱剂+爱多收+硼酸钠+磷酸二氢钾)处理效果较好,结荚率和结实率均显著高于对照。蜂引诱剂与化控剂复合使用的效果明显好于蜂引诱剂的单独使用。更多还原

【Abstract】 In this research,the soybean genetic male sterile line ms6 and the cytoplasmic male sterile line JLCMS9 were used to investigate the effects of nine chemical control agents and their combinations on the hybrid soybean seed production.The results showed that Atonik,which had a particular effect on yield improvement of the female parent,could significantly increase the pod-bearing and seed-setting rate of the two soybean male sterile lines by 28.3% and 21.4%,reach to 43.9% and 36.4%,respectively.Investigation on various combinations of the nine chemical control agents showed that mixture mainly containing Atonik(Atonik+Sodium borate+Potassium dihydrogen phosphate and Bees attractant+Atonik+Sodium borate+Potassium dihydrogen phosphate)had better effects on two sterile lines with significantly higher pod-bearing rate and seed-setting rate than the CK.We also found that when the bee attractants was mixed with other chemical control agents,the mixture could increase seed production more effectively than only used bee attractants.更多还原
