乙烯利处理对菠萝蜜果实催熟的影响

Effect of ethephon treatment on physiological index of jackfruit after harvest

以干包类型菠萝蜜"75"株系果实为试材,研究0、500、1 000、1 500、2 000 mg/L乙烯利(CEPA)处理对菠萝蜜果实成熟的影响。结果表明:乙烯利处理加速了菠萝蜜果实中淀粉、纤维素和原果胶的降解,促进了菠萝蜜果实总糖、还原糖、蔗糖含量的升高,提早了有机酸和Vc含量高峰的出现,显著地降低了菠萝蜜果实在贮藏前期的蛋白质含量,并提高了贮藏后期蛋白质和可溶性果胶的含量,其中,1 000 mg/L乙烯利处理效果最好。

With＂75＂ hard jackfruit lines as material, effect of 0, 500, 1 000, 1 500, 2 000 mg/L ethephon （CEPA） on jackfruit maturation were studied in this paper. The results showed that ethephon accelerated the degradation of starch, cellulose and protopectin content, promoted the rise of total sugar, reduced the sugar and sucrose content and advanced the peak of organic acids and Vitamin C. It markedly reduced the protein content of jackfruit in the early storage and improved the protein and soluble pectin content in the late period of storage. In all concentrations, effect of 1 000 mg/L CEPA treatment was the best.
