| 摘 要： | 以烤烟品种吉烟9号(Nicotianatobacum L.)为试验材料,通过盆栽试验,研究不同氮素形态对烤烟多酚及相关酶活性动态的影响。结果表明,氮素形态对烤烟多酚及酶活性有明显影响,移栽30d后,50%硝态氮+50%铵态氮处理多酚类物质含量明显提高。在移栽后30～75d,50%硝态氮+50%铵态氮处理POD和PAL一直保持相对较高水平,且PAL活性随着硝态氮比例的增加而增强,栽后75d达到高峰后迅速降低;在移栽后60d,75%铵态氮+25%硝态氮处理PPO活性达到峰值;生长前期APX活性随着铵态氮比例的增加而增强,移栽后75d达到峰值而后迅速降低且以50%硝态氮+50%铵态氮处理活性最强。

| Abstract: | A study was conducted on the effect of different nitrogen forms on polyphenols and related enzyme activity in flue-cured tobacco leaves.The nitrogen forms had obviously influence on polyphenols and related enzyme activity of flue-cured tobacco,the content of the chlorogenic acid,rutin and total phenols increased 30 d after transplanting,the content of polyphenols of 50% ammonium nitrogen + 50% nitrate nitrogen treatment increased obviously.POD and PAL activity of 50% ammonium nitrogen +50% nitrate nitrogen ... |
