[Effect of foliar leaching on growth and mineral nutrition of maize under NaCl stress].
The impact of foliar leaching on growth and mineral nutrition maize under NaCl stress was investigated. The results showed that there was no difference in biomass between leaching and control treatments under low NaCl stress (0 and 50 mmol.L-1), but under high NaCl stress (100 and 200 mmol.L-1), the biomass of leaching treatment was higher, with a better at pH 3.5 than at pH 7.0. The shoot K+ content in leaching treatments was higher than that of control under no NaCl stress, but lower under 200 mmol.L-1 NaCl stress. Shoot Na+ content of leaching treatments was lower than that of control under high NaCl stress, and shoot Ca2+ and Mg2+ contents of leaching treatments were higher under no NaCl stress. Root K+, Na+, Ca2+ and Mg2+ content and relative water content of leaching treatments had no significant changes, compared with those of control. It was suggested that foliar leaching could alleviate harmful degree of maize under serious salt stress, which was related with the decrease of shoot Na+ content by foliar leaching.
