以野生型辣椒6421经~(60)Co–γ辐射诱变产生的叶色黄化突变体R24–12–6为材料,比较辣椒叶色黄化突变体与野生型农艺性状、叶绿体超微结构、生理生化特性的差异。结果表明:辣椒叶色黄化突变体黄化性状受隐性单基因的细胞核遗传;R24–12–6果长比6421增加2.06 cm,果宽、坐果数和单果质量均低于野生型的,其中坐果数与6421有显著差异;叶绿素含量、叶绿素a、叶绿素b、类胡萝卜素含量较野生型降低,差异显著; R24–12–6的净光合速率、蒸腾速率、气孔导度、胞间CO_2浓度分别为6421的84.80%、87.96%、98.16%和80.51%,但差异无统计学意义;透射电镜扫描发现辣椒叶色黄化突变体叶绿体数量减少,基粒片层结...

The mutant R24-12-6 with a leaf yellow which induced by ~(60)Co - γ radiation from pepper wild type 6421was used as the material to compare the differences of agronomic characters, chloroplast ultrastructure, physiological and biochemical characteristics between the mutant and the wild type pepper 6421. The results showed that mutant R24-12-6 was inherited by recessive single gene. The fruit length of mutant R24-12-6 was 2.06 cm higher than that of the wild type 6421. The fruit width, fruit number and single fruit quality of mutant R24-12-6 we...
