【目的】明确烤烟品种HN2146的烘烤特性。【方法】以云烟87为对照,采用暗箱和电烤箱试验方法,研究HN2146中部和上部烟叶变黄变褐特性、失水特性、叶绿素降解特性及多酚氧化酶活性。【结果】（1） HN2146上部和中部烟叶暗箱变黄时间分别需48和84 h,上部和中部烟叶暗箱变褐时间分别需72和120 h,较云烟87变黄难、变褐易;（2） HN2146上部和中部烟叶失水均衡性分别为0.43和1.24,失水均衡性都较好;HN2146的中部烟叶失水均衡性要好于云烟87,HN2146的上部烟叶失水均衡性较云烟87差;（3） 72 h时,HN2146上部和中部烟叶的叶绿素降解速率分别为13.68和13.03 g/（kg·h）,降解比例分别为98.55%和93.85%,叶绿...

[ Purpose] To clarify the curing characteristics of a new flue-cured tobacco variety HN2146.[Method] By establishing Yunyan87 as control groups,the characteristics of yellowing,browning,water loss,chlorophyll degradation and polyphenol oxidase (PPO) activity of the middle and upper leaves can be studied by using dark chamber and electric-heated flue-curing barn.[ Result] (1) In the dark chamber,the yellowing time of HN2146 upper and middle leaves were 48 h and 84 h respectively,the browning time of the upper and middle leaves were 72 h and 120 h respectively.Compared with Yunyan87,the yellowin...
