Abstract
The experiment was to study the effect of exogenous salicylic acid of 0.1mmol/L spraying to the surface of the leaves on growth,chlorophyll content and mineral nutrients absorption of cotton seedlings under NaCl(100mmol/L)stress,by using nutrient solution culture to cultivate plants.The results indicated that,the SA of 0.1mmol/L spraying on the surface of cotton leaves every two days significantly improved the growth of cotton seedling,increased the fresh weight,dry weight,growth rate,the contents of chlorophyll and significantly reduced the absorption of Na+and enhanced the absorption of K+to keep the balance of Na+and K+of cotton under salt stress.Compared with excess SA on cotton seedlings spraying the leaves every two days under salt stress,excess SA spraying the leaves on cotton seedlings every day significantly reduced the relief or even aggravated the salt injury.So that SA spraying on cotton leaves every two days could promote plant growth and adjust the absorption of mineral elements to improve the ability of resistance to salt stress and reduce and alleviate the salt stress injury on cotton seedlings.
