摘　　要：对不同外形烤烟鲜烟叶的组织结构和防御酶活性进行了研究。结果表明,不同外形的鲜烟叶的组织结构存在显著性差异,防御酶活性各不相同。其中,黑褐色烟叶组织结构致密,防御酶PPO,POD和SOD活性最小,MDA活性最大;黄绿相间烟叶的防御酶POD和SOD活性最大;卷曲烟叶的组织结构非常疏松,防御酶PPO活性最大,而MDA活性最小。The organization structure and defense enzyme activity in the unflue-cured tobacco leaves of different shape were studied. The results showed that the organization structure in the unflue-cured tobacco leaves of different shape achieved the remarkable level, the enzyme activities were different, the organization structure of snuffcolored tobacco leaves was tight, the activities of PPO, POD and SOD were at the lowest point, while the activity of MDA was at the highest point. The activities of POD and SOD were the highest in the yellow and green alternative tobacco leaves. The organization structure of curly tobacco leaves was very loose, the activity of PPO was the highest, but the activity of MDA was the lowest.
