膨大剂对玫瑰香果粒膨大及其品质的影响

Effect of growth regulators on berry size and quality of Muscat Hamburg

本文以12年生玫瑰香作为实验材料,探讨了CPPU、赤霉素(GAS)、对氯苯氧乙酸(PCPA)诱导葡萄果实膨大的适宜浓度及其对果实品质的影响。结果表明: CPPU 5mg/L 、GAS 50mg/L 、CPPU5mg/L+GAS 50mg/L、CPPU 10mg/L+GAS 25mg/L、PCPA 10mg/L有效地促进了果粒的膨大,果皮花色素含量、果汁可溶性固形物含量及可滴定酸含量都高于或接近对照,果粒品质得到改善,应用灰色系统理论综合评价证实这些处理组合是比较理想的。

The optimal concentration of CPPU, GAS and PCPA for berry enlargement and the effect on fruit quality of 12-year-old“Muscat hamburg”were discussed in this paper. The results show that CPPU 5mg/L, GAS 50mg/L, CPPU 5mg/L+GAS50mg/L, CPPU 10mg/L +GAS 25mg/L, PCPA 10mg/L were effective for berry enlargement. Anthocyanin content, TSS contentand titratable acidity were close to or higher than the control and fruit quality were improved. Data analyzed by the gray systemtheory indicated these treatments above were relatively ideal.
