【摘要】 本研究以中国扁茎大豆和美国扁茎大豆为亲本,通过杂交后自交,创制的矮秆品系F03为材料,利用40 mg/L的赤霉素（GA₃）处理不同发育时期的F03,研究其对F03品系株高、茎粗、主茎节数、主茎节间长度、短果枝数、顶生花序长度的影响。结果表明,经外源GA₃处理后,F03品系的株高、节间长度、短果枝数、顶生花序长度显著增加,而对主茎茎粗、主茎节数无显著影响。更多还原

【Abstract】 In this study, a new soybean dwarf strain named F03 was improved, which was derived from the cross between fascinated soybean of China and fascinated soybean of American. In order to analyze the contribution of GA₃ on the dwarfing of F03, F03 in different growth stages were treated with 40 mg/L exogenous GA₃. The results indicated that the plant height, internode length of major stem, short pod-branch number and terminal inflorescence length increased significantly after treatment, however, stem diameter and node number of main stem were not significantly influenced by exogenous GA₃ treatment.更多还原
