摘要
以魏可葡萄为试材，于开花前13-22d，使用不同浓度（3、5、7．5mg／L）赤霉素处理，结合盛花期25mg／LG如和花后两周25mg/L CA，＋5mg／LCPPu处理。研究了不同赤霉素处理对魏可葡萄花穗长度、果实小穗节间长度、无核率和果实品质的影响。结果表明，在花前13—22d的12组处理中，花前16d7．5m∥LGA，结合盛花期25mg／LGA，花后两周25mg／LGA3＋5mg/L CPPU的处理果穗拉长效果最为显著，其果实小穗节间长度增长为对照的128．81％。使用不同赤霉素处理提高了魏可葡萄的无核率，使魏可果形变长，此外，还增加了果实可滴定酸含量，降低了可溶性固形物含量。
In order to study the effects of GA3 on the seedless rate, fruit quality, length of fruit cluster and less fruit cluster of Wink rape, Wink rape was treated with different concentrations （3, 5, 7.5 mg/L） of GA3 13 -22 days before flowering, with 25 mg/ L GA3 in peak florescence and 25 mg/L GA3 ＋ 5 mg/L CPPU 2 weeks after blossoming. The results showed that the best treatment was applying 7.5 mg/L GA3 16 days before flowering, 25 mg/L GA3 in peak florescence and 25 mg/L GA3 ＋ 5 mg/L CPPU 2 weeks after blossoming, in this treatment, the length of less fruit cluster was 28.81% higher than that of CK. Treatment with different con- centrations of GA3 significantly increased the seedless rate of Wink grape and made its fruit become long. In addition, the soluble solid content in Wink grape was reduced, and titratable acid content was enhanced by GA3 treatment.
