2种植物生长调节剂对阳光玫瑰葡萄品质的影响

以3年生阳光玫瑰葡萄（Vitis labruscana Bailey×V.vinifera L.Shine Muscat）为试验材料,研究赤霉素（gibberellin A_3,GA_3）和N-（2-氯-4-吡啶基）-N′-苯基脲[N-（2-chloro-4-pyridyl）-N′-phenylurea,CPPU]_2种植物生长调节剂的不同质量浓度、不同配比对阳光玫瑰葡萄坐果和品质的影响.结果表明：使用GA_3和CPPU能明显改善阳光玫瑰葡萄易落果、果穗稀疏和产量不稳问题,提高果实无核化程度;GA_3和CPPU混合使用较GA_3单用显著增加单果质量、穗质量、可溶性固形物含量和硬度;CPPU前期...

Summary:以3年生阳光玫瑰葡萄（Vitis labruscana Bailey×V.vinifera L.Shine Muscat）为试验材料,研究赤霉素（gibberellin A_3,GA_3）和N-（2-氯-4-吡啶基）-N′-苯基脲[N-（2-chloro-4-pyridyl）-N′-phenylurea,CPPU]_2种植物生长调节剂的不同质量浓度、不同配比对阳光玫瑰葡萄坐果和品质的影响.结果表明：使用GA_3和CPPU能明显改善阳光玫瑰葡萄易落果、果穗稀疏和产量不稳问题,提高果实无核化程度;GA_3和CPPU混合使用较GA_3单用显著增加单果质量、穗质量、可溶性固形物含量和硬度;CPPU前期质量浓度过高会增加果实空心率,过低则对果粒膨大效果不显著,CPPU后期使用质量浓度过高会降低果实可溶性固形物含量.综合比较分析,以盛花后5d用25mg/L GA_3＋10mg/L CPPU的一次性处理,盛花后1～3d和10～15d分别用25 mg/L GA_3＋5 mg/L CPPU、25mg/L GA_3（处理Ⅴ）和25mg/L GA_3＋5mg/L CPPU、25mg/L GA_3＋5mg/L CPPU（处理Ⅸ）的2次处理效果较好.

Summary Shine Muscat （Vitis labruscana Bailey X V. vinifera L. Shine Muscat） is a diploid table grape cultivar resulted from cross breeding of ＇Akitsu-21＇ （＇Steuben＇ IV. labruscana] X ＇Muscat of Alexandria＇ [V. vinifera] ） with ＇Hakunan＇ （V. vinifera） released by National Institute of Fruit Tree Science （NIFTS） in Japan. It has a large berry size, bright yellow-green pericarp, crispy and juicy flesh, musky flavor, high soluble solid content and low acidity. Fruit ripening of Shine Muscat was in middle to late August with a long shelf life. The average mass is 10.0 g and 12.4 g for seeded and seedless fruit production, respectively. The seedless berries can be commercially produced by applying gibberellin A3 （GA3） to flower and fruit clusters in full bloom and 10 to 15 days after full bloom, respectively. Under natural conditions, however, the berries of Shine Muscat are smaller, and grape clusters are relatively sparse. Besides, Shine Mus
