　　为深入了解不同成熟期与叶片组织结构之间的关系，探索适采期，采用显微制片法研究了烤烟K326和‘云烟87’的上部叶和中部叶成熟期和延迟采收期烟叶解剖结构。结果表明：随着烟叶的延后采收，叶片栅栏组织厚度、海绵组织厚度和组织比等参数呈下降趋势，细胞间隙呈逐渐增大趋势，叶肉细胞出现逐渐解体现象；不同成熟期，叶厚、栅栏组织厚等解剖参数均呈现出显著差异，同一时期，2个品种的叶厚、栅栏组织厚度等随着叶位的升高而增加；烤烟K326的采收期较‘云烟87’更长；从与烟叶品质较密切的解剖结构特性来看，K326的采收期，上部叶不应超过14天，中部叶不应超过21天；‘云烟87’的采收期，上部叶不应超过7天，中部叶不应超过14天。

For defining the relationship between the different mature period and leaf tissue structure, exploring the appropriate intake time. Using the method of slides observation under microscope, this study was conduced to investigate the anatomical structure of the maturation period and delayed period from upper and middle positions of tobacco K326 and‘Yunyan 87’. The results showed that: with the period of intake was delayed, thickness of palisade tissue and spongy tissue, the thickness ratio of palisade to spongy, and other anatomical parameters were downtrended, gap of mesophyll cells were increased, tissue cells gradually disassembled; the thickness of leaf and palisade tissue, and other anatomical parameters were varied with the different period of maturation, in the same period, with the rising of the stalk positions, the leaf thickness, the palisade tissue thickness were decreased; the intaked period of tobacco K326 longer than‘Yunyan 87’. From the dissecting features closely related to tobacco quality, it seemed that the appropriate intake time of tobacco K326, the upper position not beyond 14 days, the middle position not beyond 21 days;‘Yunyan 87’, the upper position not beyond 7 days, the middle position not beyond 14 days.
