对‘夕阳红’‘红提’葡萄盛花期喷施生长调节剂CPPU、GA3、SM。结果发现,CPPU与GA3配合施用对两个葡萄品种无核化、果粒形状和每穗粒数、单果重的影响效果最好。激素SM对两个葡萄品种的无核化效果不明显,但可提高每穗粒数与果实部分品质。单独施用一定浓度GA3对于‘夕阳红’葡萄果粒纵径增长效果明显,对两个品种葡萄每穗粒数的增加也有显著作用。另外,使用激素后两个品种果粒的形状都变得细长,改善果实风味、着色,并提高可溶性固形物含量。
On the ’sunset red’ ’red mention’ grape flowering spray growth regulators CPPU, GA3, SM. The results showed that the combination of CPPU and GA3 had the best effect on the denucleation of two grape cultivars, the shape of fruit grains, the number of grains per spike and the weight of single fruit. Hormones SM denitrification effect on two grape varieties is not obvious, but can improve the grains per spike and fruit quality. Applying a certain concentration of GA3 alone had a significant effect on the longitudinal growth of ’Red Sunset’ grapes, and also had a significant effect on the increase of the number of grains per spike of two grapes. In addition, the fruit shape of both varieties became slender after the use of hormones, improving fruit flavor, coloring, and increasing soluble solids content.
