Abstract
The genotypic difference was one of the critical factors affecting the yield and quality of tobacco.74 tobacco varieties treated with three concentrations of potassium,high(20.00 mmol/L),medium(2.50 mmol/L),and low(0.05 mmol/L) under aseptic condition,were selected as materials to study the potassium nutrition characteristics of tobacco.The results showed that the growth of tobacco was obviously limited,and the fresh weight and dry weight of tobacco were decreased under the low potassium condition.The potassium contents in tobacco leaf were reduced obviously with the decrease of potassium application.The cluster analysis of 74 tobacco genotypes showed that 22 were rich in potassium,45 were high potassium varieties and 7 were low potassium varieties.
