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.
