| Abstract: | The effects of KNO3,K2SO4 and their mixed salt stress(0,50,100,150,200 mmol/L) on the physiological and biochemical characteristics of pepper(LiangJian named)seedling were investigated.With the increasing concentration of salt,the results showed:shoot and root water content of pepper seedling increasing firstly and then decreasing,leaf SOD activity content first decreasing and then increasing while the POD and CAT showing a decrease-increase-decrease trend,content of Pro,soluble sugar,MDA and EC value showi... |
