摘　　要：汕优63制种穗期用4种激素处理喷施母本．结果表明，花调灵或花信灵与920混合喷施比单喷920花时提早，开花进程加快，柱头外露率和异交结实率提高，增产效果明显，可加快普及应用．88速效灵与920混喷效果尚需进一步试验验证．Four treatments of spraying hormones on the female parents of Shanyou 63 during its headingstage showed that in comparison with spraying GA alone, spraying it with Huatiaolin orHuaxinlin, could induce fiowering in advance, accelerate flowering process, increase stignexsertion and outcross fruiting rates, and increase grain vield obviously, indicating that thesetwo kinds of spraytng should be widely applied to seed preductbo as are as possible. The effectof spraying Suxiaoin 88 with GA3 needs to further verify.
