| 摘 要： | 通过盆栽试验,采用不同钾素水平,在打顶后夹吸不同的植物生长调节剂对烟草生长发育进行了研究。研究表明,植物生长调节剂对烟草植株的株高、茎围、最大叶面积、节距、根体积、根鲜重、倒二叶叶面积均有促进作用,其中以BR和GA3的影响最大,但对烟草植株有效叶片数没有显著的影响。较高的钾素水平对烟草植株的株高、茎围、最大叶面积、节距、根体积、倒二叶叶面积均没有显著的影响,但是能够显著增加根鲜重。

| Abstract: | The effect of top pruning and plant growth regulators on the tobacco growth and development under different potassium level by pot trail was studied in the paper.The results showed that:plant growth regulators could increase the value of plant''s truck height,stem circumference,the maximum leaf area,section distance,root volume,fresh root weight and area of the second leaf,in which it had the biggest influence to BR and GA3.But there was no significant effect on tobacco''s effective amount of leaves.There were no significant effects of applied potassium in higher level on tobacco plant''s truck height,stem circumference,the maximum leaf area,section distance,fresh root weight and area of the second leaf.How ever it had significant effect on root volume increase. |
