本试验采用水平淀粉凝胶电泳,对白凤和寿星桃及其杂交后代的儿茶酚氧化酶同工酶酶谱进行测定。白凤出现一条慢带,寿星桃出现一条快带,全部杂种一代均同时出现双亲的酶带,呈互补酶谱,在杂种一代自然授粉的后代中,酶谱发生分离。结果表明,同工酶酶带是受特定基因位点所控制。互补酶谱可用来进行杂种的早期鉴定。 In this study, horizontal starch gel electrophoresis was used to determine the catechol oxidase isozymes of Bai Feng and Shou Xing Tao and their hybrid progeny. Bai Feng appeared a slow belt, Shou Xing peach appeared a fast band, all the hybrid generation of parents are also showing the enzyme band, was complementary zymogram, hybrid generation offspring of natural pollination, zymogram separation. The results showed that isoenzyme bands were controlled by specific gene loci. Complementary zymograms can be used for early identification of hybrids.
