试验研究不同浓度６－卞氨基嘌呤（６－ＢＡ）与多效唑（ＭＥＴ）对水稻实生苗不定芽诱导的影响。结果表明：（１）６－ＢＡ可明显促进不定芽的形成；（２）单独使用ＭＥＴ不能诱导不定芽的形成，但与６－ＢＡ配合使用可明显提高水稻不定芽的诱导率，这种促进作用对于粳稻尤为明显；（３）籼、粳稻对激素的反应不同。籼稻对激素较为敏感，较低浓度的６－ＢＡ与ＭＥＴ配合使用即能诱导实生苗产生不定芽，而粳稻则对激素比较钝感，需要较高浓度的６－ＢＡ与ＭｒＬ配合使用才能诱导产生不定芽；（４）６－ＢＡ与ＭＥＴ配合使用同样能诱导籼、粳稻杂种Ｆ＿２实生苗高频率地产生不定芽
The effects of different concentrations of 6-BA and MET on the induction of adventitious buds of rice seedlings were studied. The results showed that: (1) 6-BA significantly promoted the formation of adventitious buds; (2) Addition of MET alone did not induce the formation of adventitious buds, but the combination of 6-BA with 6-BA significantly increased the induction rate of adventitious buds in rice Especially for japonica rice; (3) The response of indica and japonica to hormones is different. Indica rice is more sensitive to hormones, and lower concentrations of 6-BA and MET can induce adventitious buds in seedlings, while japonica rice is insensitive to hormones. Higher concentrations of 6-BA and MrL can be used to induce adventitious buds Adventitious buds. (4) The combination of 6-BA and MET can also induce adventitious buds of F_2 seedlings of indica and japonica at high frequency
