摘 要：
以越橘品种'瑞卡'为试材,分别于初花期、盛花期、落花期与果实膨大期喷施25、50、75、100 mg·L-1赤霉素(GA3)和5、10、15、20 mg·L-1氯吡苯脲(CPPU)以及GA3+CPPU(25+5、25+10、50+5、50+10 mg·L-1)的组合处理,研究不同时期和不同处理对越橘'瑞卡'果实品质的影响,以期为GA3与CPPU在越橘栽培生产上应用提供参考依据.结果表明:果实膨大期各处理对果实品质的影响优于开花期,并且GA3与CPPU组合处理的效果优于二者单独处理,通过主成分分析得出50 mg·L-1 GA3+10 mg·L-1组合处理综合得分最高,与对照比较,单果质量提高33.1%,可溶性固形物含量、维生素C含量、可溶性蛋白质含量和花色苷含量分别提高15.3%、13.9%、20.6%和14.4%;可滴定酸含量和种子数量分别降低15.9%和16.9%,果实综合品质较好.

摘 要：
With the blueberry cultivar ‘Reka' as the test material,sprayed different concentration GA_3(25,50,75,100 mg·L~(-1)),CPPU(5,10,15,20 mg·L~(-1)) and GA_3+CPPU(25+5,25+10,50+5,50+10,50+10 mg·L~(-1)) combined treatments in the initial flowering stage,peak flowering stage,falling flowering stage and fruit expanding stage respectively,the effect of different periods and different treatments on the quality of blueberry ‘Reka' fruit were studied.The results showed that fruit quality of different treatments during fruit expansione was better than that of flowering stage,and the combined treatment of GA_3 and CPPU was better than that of the GA_3 and CPPU alone.The principal component analysis showed that the combined treatment of 50 mg·L~(-1) GA_3+10 mg·L~(-1) had the highest comprehensive score.Compared with the control,the single fruit weight increased by 33.1%,the contents of soluble solids,vitamin C,soluble protein and anthocyanins increased by increased by 15.3%,13.9%,20.6% and 14.4% respectively,while the content of titratable acid and the number of seeds decreased by 15.9% and 16.9% respectively,the comprehensive quality of fruit was better.
