摘　　要：为找出烤烟NC297和NC102中部和上部烟叶适宜的采收成熟度,在相同生产条件下从经济性状、外观质量和化学成分协调性3个方面研究不同采收成熟度对烤烟NC297和NC102的影响。结果表明:(1)经济性状上,NC297和NC102的中部叶以封顶后26 d采收最优,上部叶分别以封顶后54 d和47 d采收最优;(2)外观质量上,NC297和NC102的中部叶和上部叶均分别以封顶后26 d和47 d采收最优;(3)化学成分的协调性上,NC297的中部叶和上部叶分别以封顶后20 d和54 d采收最协调,NC102的中部叶和上部叶分别以封顶后26 d和47 d采收最协调。综合考虑,NC297和NC102的中部叶应在封顶后26 d采收,NC297的上部叶应在封顶后54 d采收,NC102的上部叶应在封顶后47 d采收,有利于两个品种优良品质的形成。In order to research the effects of harvest maturity on yield and quality characteristics of middle and upper leaves of flue-cured tobacco NC297 and NC102,the appearance quality,economical characteristics,chemical components of cured tobacco leaves with different harvest maturity were studied. The results showed that harvested,in 26 d after topping,there were the best economic traits and appearance quality for middle leaves of both this two cultivars. and,there were the harvested in 47 d after topping best appearance quality for the upper leaves of the two cultivars,while harvested in 54 d and 47 d after topping,there were the best economic traits for flue-cured tobacco NC297 and NC102,respectively. In the main chemical components,the middle leaves harvested in 20 d after topping of flue-cured tobacco NC297 were more harmonious,which accorded with that obtained by the local practice,and in 26 d after topping for the flue-cured tobacco NC297;while in 54 d and 47 d after topping for the upper leaves of NC297 and NC102,respectively. It was concluded that the optimum harvest time was 26 d after topping for the middle leaves of the two cultivars,while 54 d and 47 d after topping were the suitable harvest time for upper leaves of flue-cured tobacco NC297 and NC102,respectively.
