对“实践八号”返回式卫星搭载循化线辣椒种子SP1代的果实性状及总蛋白表达的差异进行了观察和分析,结果表明:循化线辣椒种子经太空诱变处理后,果横径、果纵径、果肉厚、平均单果重和干物质含量等产量性状的变异系数皆大于对照,并且正向变异居多,表现为果实横径增粗,果肉加厚,平均果肉重增加;经太空诱变的循化线辣椒SP1代的果实总蛋白含量小于对照,但差异性不显著。 The differences of the fruit traits and the total protein expression of the “Practice No.8” satellite with SP1 generation of Xunhua pepper seeds were observed and analyzed. The results showed that after Xunhua pepper seeds were mutagenized by space, The coefficient of variation of yield traits such as transverse diameter, fruit length, pulp thickness, average fruit weight and dry matter content were all larger than those of the control, and the positive variation was mostly manifested as thickening of fruit diameter, thickening of pulp and increasing of average pulp weight. The total protein content of space-mutated Xunhua chili SP1 was less than that of the control, but the difference was not significant.
