高温逆境对香蕉果实采后膜脂过氧化及细胞膜透性的影响

STUDIES ON THE EFFECT OF MEMBRANE LIPID PEROXIDES AND PERMEABILITY OF BANANA FRUIT DURING STORAGE UNDER HIGH TEMPERATURE STRESS

研究了高温逆境下贮藏对香蕉果皮和果肉膜脂过氧化及细胞透性的影响结果表明：总的变化趋势是高温加速了果实膜脂的过氧化速度，果皮和果肉中丙二醛（ＭＤＡ）含量和膜透性迅速增加，果肉比果皮对高温敏感，采用乙烯吸收剂和自发气调贮藏明显延迟了膜脂过氧化和细胞膜透性增加的时间。

The study was aimed at the effect of storage under high temperatures on the peroxide of membrane lipid and permeability of both peel and pulp of banana fruit. It was demonstrated that the overall tendencies were as follows: high temperatures speeded up the peroxide of membrane lipid. The contents of MDA and the cell permeability of both peel and pulp were increased. The pulp was more sensitive to the high temperatures than the peel. The treatment with ethylene absorbent in MA storage significantly delayed the time that the MDA contents and cell permeability increased. The ethylene absorbent significantly increased storage life of banana under high temperatures.
