摘要
以簇生椒、甜色素椒、羊角椒3种类型干制辣椒为试材,研究了种子特性及种子萌发对温度响应的差异性,并通过相关分析,评价不同类型干制辣椒组合。结果表明:3种类型辣椒种子千粒质量大小顺序为甜色素椒>羊角椒>簇生椒;干椒种子粒直径与高温(33℃)下种子发芽势呈显著正相关(r=0.81~*),种子千粒质量与种子发芽势明显相关,其中与适温(25℃)发芽势、高温(33℃)发芽率呈极显著正相关(r=0.90^(**)、0.87^(**));不同类型对温度响应不同,羊角椒耐高温性较好,簇生椒耐低温性较好;同一类型不同杂交组合间对温度的响应也存在差异;羊角椒类型组合6的F1代种子发芽温度适应范围广,低温和高温环境下种子萌发率均达96%以上。
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 3types of dry pepper.The results showed that the sequence of 1 000-seed weight was Sweet pigment pepperHorn pepperClustery 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 6was wide in seed germination rate,which reached more than 96% no matter under low or high temperature environment.
