生长调节剂对夏黑葡萄果实品质的影响

摘要

以3年生夏黑葡萄为试材，研究不同浓度赤霉素和氯吡脲对葡萄果实品质的影响。结果表明：综合各品质指标，泰安地区夏黑葡萄在盛花期使用25 mg/kg赤霉素＋3 mg/kg氯吡脲，第1次处理12 d后使用50 mg/kg赤霉素效果较好。果穗修剪处理的可溶性固形物含量显著增加，成熟度增加。%The effects of applying different concentrations of GA3 and CPPU at different stages on the fruit quality of 3-year-old grape variety“Summer Black” were studied.The results showed that the treatment of applying 25 mg/kg GA3 +3 mg/kg CPPU in full-blossom period plus applying 50 mg/kg GA3 12 days later had better effect and obtained better comprehensive quality of fruits in Taian area.The treatment of fruit-cluster clipping could significantly increase the content of soluble solids and the maturity of fruits.
