不同机械伤对琯溪蜜柚采后生理生化变化影响

Effects of different mechanical damage on postharvest physiology and biochemistry of Guanxi pomelo

以琯溪蜜柚为试材,对果实进行跌落伤及划伤处理,以未经机械伤害的蜜柚为对照,研究不同机械伤处理对果实的损伤程度差异及其对果实贮藏生理品质的影响。结果表明,在6℃贮藏条件下,不同机械伤较对照组都加速果实老化进程,划伤处理对蜜柚果实贮藏品质影响最大,果实衰老程度最快,商品价值低,而120 cm跌落伤处理对果实生理品质影响大于90 cm跌落伤处理,同种机械伤间伤害程度越大,果实贮藏品质越低。

Taking Guanxi pomelos as test material, this paper studied on the effect of different mechanical damage on storage physiology quality and damage difference of pomelos, which were treated by dropping and scratching respectively, with the perfect pomelos as the control. The results indicated that different mechanical damage treatment groups can accelerate the aging process of fruits than the control group and scratching treatment had the greatest influence on storage quality of fruits which caused faster speed of aging and lower commodity value of pomelo. Morever, 120 cm dropping treatment had more influence on physiological quality than 90 cm dropping treatment, which showed the more damage degree in the same mechanical injury, the lower storage quality of fruits.
