植物生长调节剂对冷棚夏黑葡萄果实品质的影响

Effect of Plant Growth Regulators on Fruit Quality of Summer Black Grape in Cold Canopy

以冷棚夏黑葡萄为试材,研究了盛花末期喷施不同配方植物生长调节剂对其果实品质的影响。结果表明:在盛花末期使用20%赤霉酸可溶性粒剂7 500倍液+施特优375倍液进行保果,10 d后用20%赤霉酸可溶性粒剂4 000倍液+施特优200倍液+72%链霉素可湿性粉剂3 600倍液蘸穗膨大是适宜的配方,在此条件下,葡萄单粒质量、果形指数、果蒂质量、可溶性固形物含量分别为8.12 g、1.13、0.071 g、16.0%,比清水对照增加96.6%(P<0.05)、1.80%(P>0.05)、273.68%(P<0.05)、-11.11%(P>0.05),果粒着色好,综合品质较好。

Taking summer black grapes as experimental material,the effects of different plants regulators formula on the fruit quality of summer black grapes in cold canopy during the end of full blooming period were studied. The result indicated that during the end of full blooming period,using 20% gibberellic acid solubility granula 7 500 times liquid＋Shiteyou 375 times liquid to protect the fruits and 20% gibberellic acid solubility granula 4 000 times liquid ＋Shiteyou 200 times liquid ＋72% agricultural streptomycin 3 600 times liquid dipping the fringe to expand the fruit 10 days latter,was the best formula. Under the a-bove condition,the single grain weight,fruit shape index,pedicel weight,soluble solid content were 8. 12 g, 1.13,0. 071 g,16. 0%,respectively,which increased by 96. 6%（P 〈0. 05）,1.80%（P 〉0. 05）, 273. 68%（P〈0. 05）,-11. 11%（P〉0. 05）,the color of each grain was generically beautiful,the com-prehensive quality was better compared with the water control.
