    摘要:

    【目的】探索豫中地区烟叶生长期对上部烟叶质体色素的影响.【方法】以中烟100为材料,于2012年采用烟株移栽期和叶片成熟度二因素裂区试验设计.【结果和结论】移栽期和成熟度对叶绿素及类胡萝卜素含量影响显著,随着烟株移栽期的推迟,相同成熟度的叶绿素含量差异不大,但类胡萝卜素表现出先升高后降低的趋势;随着叶片成熟度的增加,叶绿素及类胡萝卜素含量递减.不同移栽期新植二烯和类胡萝卜素降解产物含量表现为5月6日>5月5日>4月27日,含量随成熟度增加表现为先升高后降低的趋势.上部叶品质以5月15日移栽的推迟5 d采收最好.

    Abstract:

    【Objective】To explore the effect of growing period on upper leaf of tobacco in the center of Henan province.【Method】 With Zhongyan 100 as the experimental material, two experimental designs which included transplanting periods and maturity of leaves, were applied in 2012.【Result and conclusion】The effects of transplanting time and maturity on the chlorophyll and carotenoid content were significant, the chlorophyll content with the same maturity had a slight difference by postponing tobacco transplanting period, but carotenoid presented the tendency that rise firstly, then drop; with the increase of maturity of tobacco leaves, the contents of chlorophyll and carotenoid declined. The contents of degradation product in neophytadiene and carotenoid showed May 6th >May 15th >April 27th episode trend; the performance of content increased first and reduced then with the maturity. Upper leaf quality which is transplanted on May 15th and picked postponement 5 days than usual,is the best.
