为了研究冷害温度(2℃)下PLD和LOX活性的变化规律,以黄瓜为研究对象,对其进行采后38,45和52℃ 30 min热水处理,测定2℃贮藏期间(15 d)黄瓜的细胞膜透性、丙二醛含量、PLD活性和LOX活性.结果表明:热水处理可以抑制果实细胞膜渗透率的升高,减少低温贮藏期间丙二醛的积累,降低黄瓜低温贮藏过程中PLD及LOX的活性,且以45℃、30 min热水处理效果最显著.

In order to study changes of PLD and LOX activity under chilling injury temperature(2℃),after being treated with hot water for 30 min at 38,45 and 52℃,cucumbers were stored at 2℃ for 15 d.Electrolyte leakage,MDA concent,LOX and PLD activity were determined.The result showed that hot water treatment resulted in lower cell membrane permeability,reduced MDA accumulation,maintained low level of PLD and LOX activity,and 45℃for 30 min was the optimum one among three hot water treatments.
