| 摘 要： | 用盆栽试验研究了不同氮素水平对烟草碳氮代谢关键酶活性的影响。结果表明,随着氮素水平的提高,淀粉酶活性有升高趋势,烟叶硝酸还原酶活性呈上升趋势。低氮水平下由氮代谢转化为碳代谢的时间提前,高氮水平下由氮代谢转向碳代谢的时间推后。综合认为中氮水平是生产优质烟叶的较好选择。

| Abstract: | The influence of various nitrogen levels on the activeness of key enzymes of flue-cured tobacco leaves in carbon and nitrogen metabolism were studied.The results showed that as nitrogen level increased the amylase activity enhanced,the nitratase activity enhanced.In low nitrogen level,the time from nitrogen metabolism to carbon metabolism was shorten;however,in high nitrogen level,the time was deferred.In summary,the mid nitrogen level should be the optimum level to attain the highest yield and quality of tobacco. |

| Keywords: | flue-cured tobacco metabolism of carbon and nitrogen amylase nitratase transferase activity |
