Evaluation Of Mitigation Effects Of Glomus Mosseae On Triticum Aestivum L., Cv. Chamran Under Drought Stress (Vol 17, Pg 1033, 2020)

The main aim of this study was to evaluate physiological and growth-associated drought tolerance responses of mycorrhiza inoculated T. aestivum L., cv. Chamran seedlings with G. mosseae in flag leaves and roots. The arbuscular mycorrhizal (AM) or non-AM wheat seedlings under normal or water-stressed conditions were assessed for growth parameters, relative water content(RWC), solute aggradation, lipid peroxidation, and enzymatic and non-enzymatic antioxidants. Outcomes reflected the enhancing influence of AM on seedlings under drought stress: mycorrhization of zero and 32.25% in non-AM and AM seedlings, respectively, fresh weight and dry weight of shoots (28.5 and 27.34%, respectively) and roots (28.86 and 31.68%, respectively), RWC (55.15%), phosphorus concentration in shoots and roots (69.25 and 95.36%), total soluble protein and carbohydrate content in shoots (52.63 and 15.80%, respectively) and roots (30.65 and 9.80%, respectively), catalase (28.66 and 31.43%), superoxidase dismutase (28.44 and 15.27%), glutathione reductase (44.62 and 18.84%), ascorbate peroxidase (15.58 and 39.49%) and reduction in proline accumulation of shoot and root (45.01 and 44.03%) and lipid peroxidation (52.27 and 57.26%) by comparison to non-inoculated stressed seedlings. Photosynthetic pigments including chlorophyll a (77.28%), chlorophyll b (51.70%), chlorophyll total (66.76%), and carotenoid (51.75%) and antioxidative secondary metabolites such as total phenolic compounds (36.25%), total flavonoid content (30%) and total anthocyanin content (29.52%) additionally increased in flag leaves of water stressed AM plants. Taking into account all the results of this study, it can be concluded that AM inoculation of wheat plants may considerably alleviate the harmful effects of water deficit stress.
