摘　　要：在水蔗草花序发育时期对花序喷施0.05g·L-1ABA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-1ABA处理,花粉育性、结实率和无融合生殖的频率与对照均没有显著性差异.By spraying 0.05 g·L^(-1) ABA aqueous solution over the panicles of Apluda mutica during inflorescence-development,the pollen fertility,ratio of seed setting,and frequency apomixes in Apluda mutica were studied.It showed that when applying 0.005 g·L^(-1) ABA as the growth regulator,there were no significant differences between treated group and control group in the above.
