摘　　要：为了解重庆烟区烤烟生育期内的生态环境差异与颜色变化差异,进一步推进"渝金香"烟叶品牌的精益生产,对不同部位烤烟生长的生态条件进行监测,并对不同部位烤烟生育期的颜色变变化进行分析。结果表明:(1)生育期内不同部位烤烟的生育期的生态环境有较大差异;(2)烤烟在生育期内亮度(L^*)不断增加,而a^*均表现为先降低后增加的趋势, b^*值表现为逐渐增加的趋势其中中部叶在成熟期明显高低上部叶;(3)典型相关分析表明气温与降雨量的变化低对烤烟颜色的变化有较大程度的影响,降雨量越低,烟叶黄色越浓。In order to understand the difference of ecological environment and color change during the growth period of flue-cured tobacco in Chongqing tobacco area, and further promote the lean production of "Yujinxiang" tobacco brand, the ecological conditions of different parts of flue-cured tobacco growth are monitored, and the color change of different parts of Flue-cured Tobacco during the growth period is analyzed. The results show that:(1) during the growth period, the ecological environment of flue-cured tobacco in different parts is quite different;(2) The brightness(L^*) of flue-cured tobacco increase continuously during the growing period, while a^* decrease first and than increase;b^* value show a gradual increase trend, in which the middle leaves are significantly higher and lower in the upper leaves at maturity;(3) Canonical correlation analysis show that the change of temperature and rainfall has a greater impact on the color change of Flue-cured tobacco. The lower the rainfall, the more yellow the tobacco leaves.
