Abstract：With the tomato cultivar'St.Semines 313'as material,the effects of temperature and light on the growth of stems,leaves and fruits were studied using the thermo-photoperiod environment monitor devices under sunken solar greenhouse condition.The results showed that during the middle fruiting stage of autumn tomato,there were highly significantly positive correlations between the daily growth of internode length and daily accumulated temperature and mean hourly temperature of the lighting period,and significantly positive correlations and optical radiation and mean daily temperature.The daily increment of intemode diameter had an highly significantly positive correlation with mean hourly temperature of the lighting period,and significantly positive correlation with daily accumulated temperature and mean daily temperature.During the middle fruiting stage of autumn tomato,there were highly significantly positive correlations between the daily growth of leaf area and daily accumulated temperature,mean daily temperature and mean hourly temperature of the lighting period,and significantly positive correlation with optical radiation.The daily growth of diameter of the second fruit in autumn season had an highly significantly positive correlation with mean hourly temperature of the lighting period,and significantly positive correlations with daily accumulated temperature and mean daily temperature,but there was no significant difference with light radiation.There was no significant difference between the growth of stems,leaves and fruits of tomato in autumn season and mean temperature during night period.
