| 摘 要： | 选择感病品系03B9 与抗病品系C24 为试材，在水培条件下，研究不同铜浓度处理对大白菜芝麻状斑点病发生、总 酚含量及多酚氧化酶活性的影响。结果表明：随着铜处理浓度的升高，两品系芝麻状斑点病的斑点数明显增加，03B9 芝麻 状斑点病发生程度明显高于C24。铜处理期间C24 总酚含量、PPO 活性较03B9 平均高出25.6% 和77.0%。试验结果初步表 明，水培条件下铜胁迫促进了大白菜芝麻状斑点病的发生，铜浓度与芝麻状斑点病发生程度有关，同时影响了叶柄总酚含量 及PPO 活性。 |
| 关 键 词： | 大白菜 芝麻状斑点病 铜元素 总酚 PPO |

| Abstract: | Taking Chinese cabbage〔 Brassica campestris L. ssp. pekinensis（Lour.）Olsson〕line 03B9 with high sensitivity and C24 with high resistance to black sesame spot as experimental materials，this paper studies the effect of different copper concentration treatments on black sesame spot， and total phenol content and PPO activity. The results showed that the sesame spots of the 2 lines were markedly increased as the copper concentration increased，and the occurrance degree of 03B9 was significantly higher than that of C24. During the copper treatments，the total phenol content，PPO activity in the petiole of line C24 were higher than that in line 03B9 with 25.6% and 77.0%，respectively. The preliminary tests showed that under hydroponic conditions，the occurrence of black sesame spot was promoted by the concentration of exogenous copper, the degree of disorder was related to the copper treatment concentration. Meanwhile, the total phenol content and PPO activity were influenced by copper. |
