粉红太妃葡萄适应性强,生长势旺盛,特抗旱,座果率高,果穗大且美观,品质优良,是我省的推广品种。但是该品种在我省部分地区表现生长过旺,花芽分化不良,果枝率低(一般只有35％左右),产量低且不稳。为此我们于1987～1988年作了应用矮壮素提高粉红太妃葡萄果枝率的试验。结果表明:粉红太妃葡萄于花前7～10天喷布 Toffee grape adaptability, vigorous growth, special drought, high fruit rate, large ears and beautiful, good quality, is the promotion of varieties in our province. However, the varieties in some areas in our province showed over-growth, poor flower bud differentiation, fruiting branches rate is low (generally only about 35%), low yield and instability. To this end, we made the application of CCC from 1987 to 1988 to improve the fruit yield of pink toffee grape. The results showed that the pink toffee grape was sprayed 7 to 10 days before flowering
