荔枝果实采收后不存在呼吸高峰。低温抑制果实的呼吸,但是,低温处理后转暖期的呼吸是逐渐升高的,其中,升高的速度可能反映出不同品种的果实对低温的敏感性。荔枝果实的某些生理变化,如呼吸、膜透性及果实品位等对低温的反应,也说明了荔枝果实品种间存在抗性上的差异,其中,果皮泄漏似乎可作为衡量果实对低温忍耐程度的指标之一。本文还研究了过氧化物酶和超氧物歧化酶在低温下的变化。 Litchi fruit after harvest does not exist respiratory peak. Low temperature inhibited the respiration of fruits, however, the respiration of warm-up period was gradually increased after low temperature treatment, in which the rate of increase may reflect the sensitivity of different varieties of fruit to low temperature. Some physiological changes of litchi fruits, such as respiration, membrane permeability and fruit quality and other low temperature response, but also shows the litchi fruit varieties have differences in resistance, of which, skin leakage seems to be used as a measure of fruit tolerance to low temperature One of the indicators. The paper also studied the changes of peroxidase and superoxide dismutase at low temperature.
