| 中文摘要: |
| 采用分光光度计和不连续聚丙烯酰胺凝胶电泳,比较分析了不同枣树品种及株系接入病原植原体后,其过氧化物酶及同工酶和苯丙氨酸解氨酶的变化。结果表明:同一枣树品种,不同发病程度的株系间过氧化物酶活性和同工酶有一定差异,抗病品种苯丙氨酸解氨酶活性高于感病品种。这两项可作为研究枣树抗枣疯病机理的重要生理指标。 |
| 英文摘要: |
| The changes of peroxidase (POD) and phenylalanine ammonia lyase (PAL) in several jujube cultivars inoculated with phytoplasmas were analyzed by using spectrophotometer and incontinuous polyacrymide electrophoretic methods. The results showed that different cultivars of the same species have different POD activity and isozymes. PAL activity of resistant cultivars was higher than that of the susceptible ones. These two indices are very important in studying the resistance of jujube. |
