本试验用聚丙烯酰胺凝胶电泳法测定枣(Zizyphus jujuba,Mill.)4个品种(金丝小枣、大枣、灰枣、黑叶枣)的叶、枝皮及果实的过氧化物酶同工酶年周期变化。发现酶带的表达与器官和组织的生长发育有关。迅速生长期的酶带较成熟和衰老期的少。器官达到一定成熟期时,酶谱不再变化,处于相对稳定期。不同品种变化趋势一致
In this study, polyacrylamide gel electrophoresis was used to determine the peroxidase activities in leaves, branches and fruits of four varieties (Zizyphus jujuba, Mill.) (Zizyphus jujuba, Zizyphus jujuba, Isoenzyme cycle changes. It was found that the expression of the enzyme band was related to the growth and development of organs and tissues. Rapid growth of the enzyme band more mature and less aging. When the organ reaches a certain mature stage, the zymogram no longer changes, and is in a relatively stable period. Different varieties of the same trend
