Effect of Mycorrhiza Applications on Some Physiological and Macro-MicroElement Contentsin Soybean (Glycine max L.) Grown under Salt Stress Condition

This study was carried out to determine the effects of mycorrhizalapplications on some biochemical and macro/micro nutrient characteristics ofsoybean (Glycine max L.) under salt stress (0, 50, 100, 150, 200 mM NaCl). In theresearch 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 (3.57-4.72µg g-1 TA), proline (0.43-1.81 µg g-1 TA), malondialdehyde (MDA) (13.1-18.3nmol g-1), and several macro- and micro-elements, including Ca (9.43-12.8 g kg1), 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 (3.03-3.46g 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 gkg-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 initialincreasefollowed 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 contentsin mycorrhiza -treated plants under salt stress. The levels of Ca, K and Naincreased, while Mg levels remained statistically insignificant, following afluctuating pattern.. Additionally, boron applications were found to increase thenitrogen balance index, MDA, flavonol, anthocyanin, antioxidant and phenoliccontents. Overall, the study demonstrated that mycorrhiza applications have abeneficialand regulatory effect on the biochemical composition and macro/microelement levels in soybean under salt stress.
