- Abstract
The research aimed to study the characteristic of ionic homeostasis of annual seedlings of Papains Xeuramericanna under irrigation with non-magnetized and magnetized 0 or 4.0 g · L-1 NaCl solution for 30 days in the growing season. The ion contents of K+, Na+, Ca2+ and Mg 2+ in the leaves and roots were measured by atomic absorption spectrophotometry (AAS). The ion homeostasis coefficient (A) and the ion selective transport coefficient (SXi,Na) from root system to leaves were analyzed. Compared with the unsalted treatment, the ion contents of Na+ and Ca2+ SK,Na and SMg,Na increased in leaves and roots under NaCl stress, while the K+ and Mg2+ ion content, the ratio of K+/Na+ and SCa,Na decreased. Compared with the non-magnetized NaCl solution (NM), the magnetized NaCl solution (M) made leaves and roots maintain lower content of Na+ but higher content of K+ and the K+/Na+. Compared with the NM, the content of Ca 2+ decreased while that of Mg 2+ increased in the M. In M, K was higher than that in NM, and there was significant increase in the leaves than that in the roots. The ratios of Sk,Na and SMgNain leaves and roots in M were higher than those in NM, while the ratio of .SCa,Na was lower. The magnetized NaCl solution decreased Na+ content, increased K+, Ca2+ and Mg2+ content, and maintained higher K+ /Na+, which was beneficial for the physiological metabolism of the whole plant. So, the magnetic effect could promote the re-establishment of ionic homeostasis by ions selective absorption and transportation under NaCl stress.
