Abstract：In order to make use of chlorophyll fluorescence parameters to distinguish the tolerance to low temperature of different tomato varieties and low light ability,chlorophyll fluorescence parameters of 5 to-mato cultivars were measured on 5,10,15 d and 15 d after low temperature and low light treatment. The results showed that,after sub-low temperature and low light for 10 d,the five tomato varieties were divided into three tolerance types to low temperature and low light by ΦPSII,qP and P value. Combined with the correlation analysis of chlorophyll fluorescence parameters and TIVG, correlation coefficients betweenΦPSⅡ,qP,P,TIVG and TIVG were all 0. 85,significantly positive correlated. Therefore,after sub-low tempera-ture and low light for 10 d,a batch of tomato germplasms could be divided into different tolerance types to low temperature and low lightby the 3 chlorophyll fluorescence parameters in a certain extent,providing reference for identification and evaluation of tomato tolerance to low temperature and low light.
