| 摘 要： | 为探究果实生长期间套不同颜色纸袋对芒果采后果实软鼻病和贮藏特性的影响,本试验以套黄、白袋凯特芒果(Mangifera indica L.cv. Keitt)为试验材料,比较研究了两种套袋果实采后软鼻病发病率、硬度及糖代谢的差异。结果表明,在常温贮藏下(10 d),套黄袋芒果采后果实的软鼻病发病率显著低于套白袋芒果(P<0.05),而且采后果实果肉的淀粉酶、酸性转化酶(AI)、中性转化酶(NI)和蔗糖磷酸合成酶(SPS)活性均显著低于套白袋芒果(P<0.05),因而缓解了果实淀粉含量的下降速率和蔗糖积累的速率,延缓了果实的软化成熟进程,提高了采后果实的耐贮性。另外,套袋影响采后芒果果肉的蔗糖糖代谢可能与果实软鼻病的病情发展相关。本研究为选取合理有效的芒果套袋材料提供了一定的参考依据。

| Abstract: | In order to explore the effects of different colored bagging on postharvest soft nose and storage characteristics, the incidence of soft nose and sugar metabolism in mango fruit Mangifera indica L.cv. Keitt pre-harvest bagged with yellow or white bag were investigated during storage. The results showed that the bagging with yellow bag significantly reduced the incidence of soft nose disease in mango fruit during storage for 10 d compared to bagging with white bags. In addition, the bagging with yellow bags significantly decreased the activities of amylase, acid invertase (AI), neutral invertase (NI), sucrose phosphate synthase (SPS) and sucrose synthase (SS) in flesh of the mango fruit, which resulted in slowing the rates of decrease in starch content and accumulation of soluble sugar content, and in turn to be contributed to delaying the softening rate and improving the fruit storability of mango fruit during storage. It was suggested that the bagging treatment affected the sugar metabolism would be associated with the development of soft nose disease in Keitt mango fruit during postharvest. Our present work might provide references for selecting reasonable pre-harvest bagging materials of mango fruit in practice. |
