摘要:

质体色素对烟草生长发育具有重要作用,研究了毕节地区烤烟上部叶质体色素含量变化,结果表明:上部叶叶绿素a、叶绿素b、总叶绿素和类胡萝卜素的含量随着生长发育的时间均呈下降趋势。烤烟调制后同一海拔条件下不同基因型烤烟上部叶质体色素含量存在极显著差异。相同基因型烤烟在不同海拔条件下上部叶质体色素含量存在极显著差异,叶绿素/类胡萝卜素比值变化结果:云烟87为高海拔>低海拔>中海拔,云烟97和毕纳1号为中海拔>高海拔>低海拔。

Abstract:

Chromo-plast pigment plays an important role in tobacco growth. In this paper, changes in chromoplast pigment content of tobacco upper leaves planted in Bijie area was studied. The result indicated that the contents of chlorophyll a, chlorophyll b, total chlorophyll and carotenoid in upper leaves showed a downward trend during the growing and development period. After modulation of flue-cured tobacco, tobacco upper leaves chromo-plast pigment contents of different genotypes under the same altitude were significantly different. The tobacco upper leaves chromo-plast pigment contents of the same genotype under different altitudes were also remarkably different. The ratio change of chlorophyll/carotinoid of Yunyan No.87 is high altitude>low altitude>middle altitude, while the ratio of Yunyan No.97 and Bina No.1 is middle altitude>high altitude>low altitude.

Key words: flue-cured tobacco (Nicotiana tabacum), chromo-plast pigment, altitude, upper leaves
