With the wild species(Capsicum frutescens) and the representative cultivars with different fruit types as materials,the effects of low temperature on the biochemical indices of chili seedlings were studied in artificially controlled condition.The results showed that the proline content in low-temperature treated chili leaves was very significantly higher than that of the control and the content of soluble sugar increased significantly,too.Capsicum frutescens had the best tolerance to low temperature with the minimum chilling injury index;second were 419 and HZ;431 had the worst tolerance.On the whole,Capsicum frutescens had the highest tolerance to low temperature with all the indices superior to those of the cultivars.
