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。
Three varieties of dried peppers such as cluster pepper, sweet pepper and Chinese goose pepper were used as test materials to study the difference of seed characteristics and seed germination to temperature, and the correlation analysis was used to evaluate the combination of different types of dried pepper. The results showed that the order of the quality of 1000 seeds of three types of pepper seeds was sweet pepper> sheep pepper> turtle peppers; the diameter of dry seeds was positively correlated with the seed germination potential at high temperature (33 ℃) (r = 0.81 ~ *) , Seed quality was obviously correlated with the seed germination potential, and there was a significant positive correlation (r = 0.90 ~ (**), 0.87 ~ (**)) with the germination potential at 25 ℃ and the germination rate at high temperature )); Different types of different temperature response, the horn horn pepper is better, the low temperature tolerance of cluster pepper is better; the same type of hybrid combinations also have differences in response to temperature; F1 generation of pepper combination type 6 seed germination A wide range of temperature adaptation, low temperature and high temperature seed germination rate reached more than 96%.
