【摘要】 CPPU有促进果实增大的作用,但同时也有促进果实软化和腐烂、降低可溶性固形物含量的负面效果。以翠玉和丰悦猕猴桃为试材,研究了5、1、0.2mg/L3个浓度CPPU处理对猕猴桃果实大小、品质及贮藏性的影响。结果表明:5mg/L处理能使单果重增加17.8%,但显著降低了果实的可溶性固形物含量,加速了常温下果实软化和腐烂速度,增加了烂果率。0.2mg/L处理对果实生长及品质无明显作用。1mg/L处理可使单果重增加11.4%,而对果实硬度和可溶性固形物含量及腐烂速度无不良影响。因此,在猕猴桃生产上对CPPU的最适使用量为1mg/L,同时必须加强栽培管理,培育强壮树势。更多还原

【Abstract】 CPPU could accelerate the growth of fruit, but it also could accelerate the softening and decay of fruit, and reduce the soluble solids content (SSC) at the same time. Effects of three CPPU treatments with different concentration (5, 1 and 0.2 mg/L) on fruit size, quality and storage property of kiwifruit were studied in this paper and the kiwifruit Cuiyu and Fengyue were taken as experimental material. The results showed that the average fruit weight increased by 17.8% under the treatment of 5 mg/L CPPU, while SSC decreased remarkable, the speeds of fruit softening and decay were accelerated and the rotten fruit rate was also increased. There were no significant effects of 0.2 mg/L CPPU on growth and quality of kiwi fruit. The average fruit weight could be increased by 11.4% under the treatment of 1 mg/L CPPU, but no harmful effects on SSC, fruit firmness and rotten speed. These results indicated that the optimum applied amount of CPPU on the production of kiwifruit is 1 mg/L, and it should enhance the management of cultivation and breed strong tree seedlings at the same time.更多还原
