| Abstract: |
| The paper studied the effect of top pruning and plant growth regulators on tobacco growth and development under different potassium level by pot trail.The results showed that: There were no significant effects of applied potassium in different level on tobacco plant's truck height,the maximum leaf area,root volume and area of the second leaf from below,but could significantly effect fresh root weight on increase.While plant growth regulators after top pruning could increase the value of plant's truck height,the maximum leaf area,root volume,fresh root weight and area of the second leaf from below.The plant growth regulators could significantly increase the content of K in all of part of tobacco leaves and the K accumulation,and could promote potassium transfer from root and stem to leaf,so improve the quality of tobacco leaf,the BR and GA3 treatment more better. |
