摘要
以巴西香蕉果实为材料 ,研究果实后熟过程中呼吸速率、活性氧、淀粉酶、膜脂过氧化和电导率的变化 ,结果表明 :活性氧、呼吸速率、淀粉酶活性高峰依次出现 ,并伴有膜脂过氧化及膜透性增大 ,初步证实活性氧 (尤其是O- ·2 )
The changes of respiratory rate,active oxygen levele,amylase activity,MDA content and electric conductivity were investigated during the ripening of banana fruit.The result showed that the maximum value of active oxygen(O -· 2,H 2O 2)production,respiratory rate and amylase activity appeared in order,with the content of MDA and membrane permeability increased gradually.It was initially proved that active oxygen(in particular O -· 2)was significantly correlated with the senescence of banana fruit.
