摘要: ‘夏黑’是南方无核葡萄避雨栽培的主栽品种,由于其三倍体核不育性,生产上常需膨大处理。为探寻一种省力又有效的膨大处理方案,研究比较了1次膨大与2次膨大处理的方案,探讨不同处理时期、试剂配比和浓度对葡萄果实膨大效果的影响。结果显示‘,夏黑’2次膨大处理在盛花期用浓度为30mg/L的GA3溶液浸果,15天后使用GA320mg/L+CPPU3.5mg/L进行第2次膨大处理,果实穗重达400g,粒重6.33g,可溶性固形物含量18.4%。1次处理在盛花后3天左右,使用GA350mg/L+CPPU2.5mg/L对果实进行1次浸果处理,穗重400g,粒重5.56g,可溶性固形物含量18.0%。

Abstract: ‘Summer black’is one of the main grape varieties under shelter cultivation in south China. Due to its triploid nucleus sterility, enlarging fruit is required in production. To discover an effective method, this study compared once-treatment with twice-treatment by applying different formulations at different periods. The results showed that in twice-treatment of‘Summer black’, soaking was conducted with a concentration of GA3 30 mg/L at blooming stage, then GA3 20 mg/L plus CPPU 3.5 mg/L was applied after 15 days. Under this treatment, fruit ear weight could reach 400 g, berry weight was 6.33 g, and total soluble solid content reached 18.4%. In once-treatment, GA3 50 mg/L plus CPPU 2.5 mg/L was applied for soaking 3 days after full blossom, fruit ear weight could reach 400 g, berry weight was 5.56 g, and total soluble solid content was 18.0%.
