中文摘要:
      通过田间试验研究了烟株打顶后喷施外源生长活性剂17号(T1T7)对烤烟上部叶片组织结构、钾和烟碱含量的影响。结果表明,外源物质可促进上部叶面积增大,调节叶片栅栏组织、海绵组织厚度和栅栏组织细胞密度的动态变化,促使叶片厚度降低,组织变得较为疏松,促进钾素含量提高和烟碱含量降低。总体上T1、T4和T7改善上部烟叶组织结构,提高钾素含量的效果较为明显。
英文摘要:
      After topping, the effect of exogenous substances T1~T7 on the leaf tissue structure and the content of potassium and nicotine of upper leaves of flue-cured tobacco was studied in the field experiment.The results showed that exogenous substances could promote the upper leaf area increase, and accommodated the thickness of palisade tissues, spongy tissues and the cell density of palisade tissues dynamic changes, and decreased leaf thickness, loosen the tissue, and increased the potassium content, while reduced nicotine content.In general, T1, T4 and T7 treatments were optimized in improving the leaf tissue structure and incresing potassium content.
