Abstract:
‘Wu Yueman’ Brassica chinensis L.seedling was used as test material,to explore seedlings height,leaf area,aerial dry weight,POD activity and SOD activity under different salt stress concentration and SA soaking,in order to study the effect of soaking seeds with salicylic acid on aerial growth and physiological characteristics of Brassica chinensis L. seedling under salt stress.The results showed that,under the same salt stress and different concentration of SA,all items showed low improve and high prohibit.The best soaking concentration was 1.00 mmol?L-1.Under the same SA soaking concentration,seedlings height,leaf area and aerial dry weight decreased with salt stress rising.However,the activities of POD and SOD rised under 50 mmol?L-1 salt stress and then decreased.This experiment showed that some concentration of SA soaking could prevent the aerial growth and physiological from salt stress.
