Abstract:
Clustery pepper,Sweet pigment pepper and Horn pepper were taken as experimental materials.Seed characteristics,seed germination in different temperature condition,and its correlation analysis were studied to evaluate 3 types of dry pepper.The results showed that the sequence of 1 000-seed weight was Sweet pigment pepper>Horn pepper>Clustery pepper.There was a significant positive correlation between seeds diameter and germination potential in high temperature(33 ℃)(r=0.81*).There were the extremely significant positive correlation between 1 000-seed weight and germination potential in optimum temperature(25 ℃)and germination rate in high temperature(33 ℃)(r=0.90**，0.87**).The response of different types and different combinations in same type of dry pepper on the germination under different temperatures were different.Horn pepper had better high temperature tolerance and Clustery pepper had better tolerance to low temperature.The adaptive range of combination 6 was wide in seed germination rate,which reached more than 96% no matter under low or high temperature environment.
