| 摘 要： | 探索在河南气候条件下陈化的不同地区烤烟中多酚氧化酶(PPO)、过氧化物酶(POD)、脂氧合酶(LOX)、苯丙氨酸解氨酶(PAL)活性的变化规律。结果表明:(1)在不同陈化阶段,国内4个烟区烟叶中各酶活性表现为在烟叶陈化初期呈现逐渐增加的趋势,到陈化6个月或者9个月时酶活性达到最大值,之后酶活性逐渐降低。(2)在24个月的陈化进程中,各地区的烟叶中4种酶的酶活均较其陈化初始降幅有所不同,其中湖南烟区烤烟过氧化物酶和苯丙氨酸解氨酶活性降低幅度最大,分别约为77.01%和14.15%;多酚氧化酶则以云南烟叶降幅最大,为66.67%;贵州烟叶的脂氧合酶活性降低最多,为68.93%。(3)津巴布韦烟区烤烟各酶活在15～39个月时逐渐降低,且活性相对较低,以脂氧合酶活性降幅最大。

| Abstract: | In order to explore the changing laws of the activity of the polypgenol oxidase,peroxidase,lipoxygenase and phenylalanine ammonialyase in the flue-cured tobacco leaves during the aging stage in different areas under the Henan atmosphere condition.The results showed that:(1) at different aging times,the activity of every enzyme gradually increased in the beginning period,and the amount peaked at the aging of the 6th or 9th months,then diminished gradually;(2) the activities of enzymes in different areas had ... |
