摘 要 ：在水蔗草花序发育时期对花序喷施0．05g／L 2，4-D后．对水蔗草的花粉育性、结实率和无融合生殖的频率进行研究，结果表明：用0．05g／L 2，4-D处理，花粉育性和结实率与对照均没有明显的差异；无融合生殖的频率比对照显著下降。

Abstract:The growth regulators were applied by spraying panicles with 0.05 g/L 2,4-D aqueous solution during inflorescence development stage.Pollen fertility and ratio of seed setting showed no difference between treated and untreated plants in two-year study.Freq
