摘　　要：以‘金田蓝宝石’葡萄为试材,对其进行不同浓度的赤霉素(GA3)、氯吡脲(CPPU)无核化处理,以期得出该品种无核化处理的适宜方法。结果表明,第一次在盛花期使用GA_(3)75 mg·L^(-1),第二次在花后10~14 d使用GA_(3)25 mg·L^(-1)+CPPU 2 mg·L^(-1)时效果最好,无核率为83.33%;此外,果形指数、穗梗粗度、粒质量、果柄长度、果柄粗度、果实硬度相比对照均有所增加,果实的可溶性固形物、可溶性糖、还原糖、可溶性蛋白含量也有所提升。因此,此处理下果实的无核化效果理想,且提高了果实的商品价值,本试验可为‘金田蓝宝石’葡萄无核化生产提供参考。Using'Jintian Lanbaoshi'grape as the test material,different concentrations of gibberellin(GA3)and chlorpyramide(CPPU)were used for seedless induction,in order to find out the appropriate method to get seedless grapes.The results showed that the effect was the best with GA375 mg·L^(-1)at the full flowering stage for the first time,and then GA325 mg·L^(-1)+CPPU 2 mg·L^(-1)was used at 10-14 d after flowering for the second time,the seedless rate was 83.33%.In addition,fruit shape index,spike peduncle thickness,berry weight,fruit stem length and thickness,and fruit hardness increased to compare with the control,and the contents of soluble solids,soluble sugars,reducing sugars and soluble protein also increased.The external quality and internal quality of fruit were better than the control.Therefore,seedless induction effect of fruits under this treatment was ideal,which improved the commercial value of'Jintian Lanbaoshi'fruit,and this test could provide a reference for the seedlessness production of'Jintian Lanbaoshi'grape.
