摘要
以22个不同番茄品种为材料,在温度8℃/5℃（昼/夜）、光照强度4000lx处理5d后,以温度25℃/15℃（昼/夜）为对照进行抗冷性鉴定。分析探讨了番茄幼苗的相对电导率、丙二醛、VC含量及过氧化氢酶活性（CAT）4个生理指标的变化及其与抗冷性的关系,筛选出了抗冷性较强的番茄品种。
Take 22 different tomato varieties （lines） as experiment materials to identify the chilling resistance. Treatmant condition was as follows： the treatment temperature 8 ℃/5 ℃ （day/night）, illumination intensity 4 000 lx, treatment time 5 d, at the same time, took temperature 25 ℃/15 ℃ （day/night） as control. The experiment analyse the relationship between the chilling resistance and changes of four physiological indices including relative electric conductivity, MDA, VC content, and catalase activity, screened the varieties oftomato with high chilling resistance.
