摘  要：
用树干注射和叶面喷施2种方式研究几种常用外源植物激素对麻疯树开花的影响。试验结果表明,树干注射效果优于叶面喷施;IAA、IBA、NAA、GA3对麻疯树花枝比例影响不显著,IAAI、BA、NAA对麻疯树小花数量及雌花比例影响不显著,对麻疯树雌花比例有显著影响;不同浓度GA3对麻疯树花枝比例、小花数量及雌花比例的作用效果均有明显差异。认为给麻疯树树干注射100×10-6的GA3有助于提高雌花数量。

摘  要：
Effects of external plant hormones on the blossoming of Jatropha curcas flowers were studied by trunk injection and foliage spraying.Trunk injection was better than that of foliage spraying.No significant differences were found among the ratios of flower shoots after applying hormones of IAA,IBA,NAA,and GA3,The flower number and the ratio of female flower also exhibited no difference after applying IAA,IBA,and NAA,but significant differences were found among the ratio of female flowers.GA3 with different concentrations had significant influences in the ratio of flower shoots,flower number,and ratio of female flowers.Experimental results indicated that J.curcas can increase the number of flower by trunk injection 100×10-6 GA3.
