Effect of Mycorrhiza Applications on Some Physiological and Macro-Micro Element Contents in Soybean (Glycine Max L.) Grown Under Salt Stress Condition

Abstract

This study was carried out to determine the effects of mycorrhizal applications on some biochemical and macro/micro nutrient characteristics of soybean (Glycine max L.) under salt stress (0, 50, 100, 150, 200 mM NaCl). In the research investigated chlorophyll a (17.30-22.61 µg g-1 TA), chlorophyll b (3.05-5.78 µg g-1 TA), total chlorophyll (20.46-27.72 µg g-1 TA), carotenoids (3.57-4.72 µg g-1 TA), proline (0.43-1.81 µg g-1 TA), malondialdehyde (MDA) (13.1-18.3 nmol g-1), and several macro-and micro-elements, including Ca (9.43-12.8 g kg-1), K (9.97-11.8 g kg-1), Na (0.94-3.52 g kg-1), P (1.49-2.44 g kg-1), Mg (3.03-3.46 g kg-1), Zn (3.71-7.63 g kg-1), K/Na ratio (3.32-7.17%), Mn (23.6-56.5 g kg-1), Mo (0.81-1.26 g kg-1), Cu (0.76-1.78 g kg-1), As (2.17-5.26 g kg-1), Ni (0.99-1.97 g kg-1), Pb (0.07-0.12 g kg-1), Cd (0.06-0.13 g kg-1), Co (0.06-0.08 g kg-1) and Cr (0.78-1.48 g kg-1). As a result of the study; a decrease or an initialincrease followed bya decrease was observed inin chlorophyll a and b, total chlorophyll, carotenoids, P, Zn, K/Na, Ca/Na, Mn, Mo, Cu, As, Ni, Pb, Cd, Co and Cr contents in mycorrhiza-treated plants under salt stress. The levels of Ca, K and Na increased, while Mg levels remained statistically insignificant, following a fluctuating pattern.. Additionally, boron applications were found to increase the nitrogen balance index, MDA, flavonol, anthocyanin, antioxidant and phenolic contents. Overall, the study demonstrated that mycorrhiza applications have a beneficialand regulatory effect on the biochemical composition and macro/micro-element levels in soybean under salt stress. © 2025, Centenary University.
