Abstract

By plot experiment,a study was conducted on the dynamic effects of 3 different root regulatiors,ABT 4,FA and FeSO 4 on activity of root system,nicotine synthesis,K uptake and their distribution in various organs of tobacco.The results showed that the dynamic change of activity of root system took on a curve with double peaks,and the content of nicotine in root and leave was in accordance with the root activity tendency,and the first peak appeared 30 days after transplanting,the other 70 or 80 days after transplanting.There was a dynamic change of K content in root,leave and stem,they were on the decline in the whole stage.ABT 4,fulvous humate and FeSO 4 could promote the activity of root system,K uptake and nicotine synthesis,but their functions were different during different stages.
