摘要: 以烤烟新品系华烟06为供试材料,研究苗期不同剪叶次数对旺长期至成熟期烤烟叶片含氮化合物代谢及酶活性的影响。结果表明:在剪叶1~4次的频次范围内,J3处理显著提高了烤烟叶绿素(Chl)含量,但J4处理叶绿素含量较J1、J2处理降低;J3、J4处理较J1、J2处理显著提高烤烟的硝酸还原酶(NR)活性和烟碱含量;至烤烟生长后期,J4处理的总氮、游离氨基酸(FAA)、蛋白质含量较高,而J3处理却较低。总体看来,J4处理烤烟后期氮素的吸收和合成转化能力提高,而J3处理虽然氮素吸收能力升高(NR活性较强),但合成能力下降(总氮、FAA、蛋白质含量低)。

Abstract: With Huayan06 as the tested material,effects of clipping times in seedling stage on metabolization of?nitric compounds and enzyme activity of flue-cured tobacco leaves from vigorous growing stage to maturity stage were?studied. The results showed that,in 1-4 clipping times,treatment of clipping 3 times increased the chlorophyll chlorophyll content of tobacco,but treatment of chipping 4 times decreased the chlorophyll content compared with chipping 1 times and chipping 2 times. Effects of adding clipping times to increase activity of nitrate reductase (NR)?and nicotine content were significant. In maturity stage,contents of total nitrogen,FAA and protein of clipping 4?times treatment were higher,but those of clipping 3 times were lower. All things considered,treatment of clipping 4?times improved the capability of nitrogen absorbtion and conversion synthesizing,although treatment of chipping 3?times improved the capability of nitrogen absorbtion,but decreased the capability of nitrogen synthesizing.
