- 摘要:
- 以满天星组培正常苗和玻璃苗为材料, 通过生理生化特性、同工酶分析, 探讨了满天星试管苗玻璃化发生原因。结果表明:玻璃苗组织含水量较高, 为 95.8%, 而正常苗为91.7%。 玻璃苗的各种叶绿素平均含量及可溶性糖和还原糖含量分别为正常苗的 14.0%, 63.8%和 86.9%;而玻璃苗的过氧化物酶(POD)的活性增加, 是正常苗的 2.6倍。 采用聚丙烯酰胺凝胶电泳法对酯酶同工酶进行分析结果表明, 玻璃苗的酯酶同工酶电泳谱带出现缺失的异常现象, 同时其谱带颜色较浅;过氧化物同工酶电泳结果表明玻璃苗与正常苗相比活性增加且谱带增多。
- Abstract:
- Normal and vitrification shoots was used in this experiment for proving up the mechanism of vitrification in Gyp-sophila paniculata L.through physiological and biochemical characteristic, EST isozyme activity .Water content of vitrifica-tion shoot(95.8%)was higher than that of normal shoot(91.7%).For Chlorophyll average content, solubility and reductivesugar content, vitrification shoot was 14.0%, 63.8%and 86.9% of normal shoot, respectively , but POD activity of vitrifica-tion shoot increased, was 2.6 folds of normal shoot.The result of EST isozyme analysis using PAGE method, electrophoresisof EST isozyme appeared abnormity of lacking band, moreover band color was slight.In vitreous shoots the electrical con-ductivity and the activity of POD increased.
