为研究烤烟上部叶采收的最适成熟特征,将云烟87上部叶按不同成熟度进行分次采收,通过外观质量和感官质量评价确定常规采收时间推迟5 d即移栽后125 d(M2阶段)对烤烟进行一次性采收,烟叶质量最优。其中移栽后125 d的顶3~顶1叶(TM2)的外观质量和感官质量评分为44.67和71.79;移栽后125 d的顶6~顶4叶(FM2)为43.36和71.75;均优于其他几个阶段。从叶片结构的细胞学变化规律看出,随着烟叶成熟度的提高,栅栏组织和海绵组织在移栽后125 d(M2阶段)开始变得疏松、细胞间隙增大、细胞中各种细胞器开始降解、淀粉颗粒积累到最饱满状态。其中移栽后125 d的顶2叶的栅栏组织厚度、海绵组织厚度、栅栏组织细胞密度...

In order to study the optimum mature characteristic of tobacco upper leaves for plucking, the appearance and sensory qualities of YunYan87 upper leaves were analyzed. The results showed that the date of 125 days after transplanting (M2) was the best stage of one-time plucking of upper leaves. The appearance and sensory qualities scores of the top3-1 leaves at the date of 125 days after transplanting (TM2) were 44.67 and 71.79 respectively, and the top6-4 leaves at the date of 125 days after transplanting (FM2) were 43.36 and 71.75, which were a...
