摘　　要：对烤烟品种龙江911不同部位、不同成熟度的鲜烟叶组织结构进行了观察,同时测定了其叶绿素、胡萝卜素的百分含量。结果表明,上、中、下不同部位烟草叶片的叶片厚度、栅栏组织厚度、海绵组织厚度及栅栏组织与海绵组织厚度比值均随成熟度的增加而下降;细胞间孔隙度随成熟度发展而增大;叶绿素a、叶绿素b、总叶绿素和类胡萝卜素含量也随成熟度的增加而降低。The tissue structure of fresh tobacco leaves to Long-jiang911 in different position and different maturity was observed. And at the same time the content of chlorophyll and carotene was measured. The results showed that the thickness of leaf, the thickness of palisade tissues, the thickness of spongy tissues, the thickness ratio of palisade tissues and spongy tissues in different part of tobacco leaf were all reduced with maturity, the porosity among cells were increased with maturity. The contents of chlorophyll a, chlorophyll b, total chlorophyll and carotene were reduced with maturity.
