摘要
离体葡萄果实接触二氧化硫气体,在发生伤害的情况下,可引起细胞汁液pH的降低和组织质膜差别透性的增加,这种变化在一定范围内与硫伤害程度相关。电导率在伤害出现前有一峰值,而pH值呈较缓的降低趋势。以电导率变化做为细胞功能恢复的参照指标,结果表明“无核白”葡萄比“沙力皮”葡萄有较强的伤害恢复能力。
Under the circumstances of injury occurrence, it would cause a decrease in pH of cell juice and an increase in permeability of cell membrane while vine-left grapes got in touch with SO_2. Take the conductivity rate change as the reference index of cell function recovery, it shows that the recovery ability of Wuhebai is stronger than that of Shalipi.
