Mycorrhizal inoculation under water stress conditions and its influence on the benefit of host microbe symbiosis of Terminalia arjuna species

Abstract

Background Entisol is a very poor, compact, and low-water-holding capacity soil. They are obstacles to the plant's root system's penetration and the availability of water, particularly in dry months. However, Arbuscular mycorrhizae fungi (AMF) is used for seedling growth and reduces water stress in the plant. Results In this experiment, the growth parameters and the physiological activities of the plant were changed for the well watering (WW), fractionated watering (FW), and stopped/no watering conditions of the T. arjunaseedling. This experiment demonstrated higher mycorrhizal dependency (24.90%) under the FW condition than that of the WW condition (18.58%). Also the root colonization was higher (67%) under FW plants compared to WW plants (53%) associated with AMF+ in T. arjuna seedling. Photosynthesis was found 24.27% more with FW than the WW condition. Experiment' shows posivitivecorrelation between the photosynthesis and interval of no watering for AMF− plants (r2 = 0.873 for AMF− (control) and comparatively very weak for plants with AMF+ (r2 = 0.259 for AMF+ plants). Conclusions The findings confirms the use of AMF in entisol soil to improve plant growth and biomass by reducing edaphic stress.

Physiological and Enzymatic Antioxidant Responses of Solanum tuberosum Leaves to Arbuscular Mycorrhizal Fungal Inoculation under Water Stress

“…In other potato varieties, gs also decreases when water stress is more severe [ 29 ]. Regarding the role of AMF symbiosis, in Terminalia arjuna plants inoculated with AMF, a decrease in gs was reported when water stress was applied [ 32 ], although the opposite effect has also been shown in Vitis vinifera leaves [ 33 ]. In Solanum lycopersicum plants subjected to mild and moderate drought stress, gs decreases significantly with respect to that of the control [ 34 ].…”

“…In contrast, in previous studies using wheat plants subjected to water stress in which the CC fungus was used, no significant differences were detected in the photosynthetic rate with the application of stress [ 36 ]. Increases in WUE have been reported in Cinnamomum migao plants [ 37 ], Terminalia arjuna plants [ 32 ], and some wheat varieties [ 36 ] with the application of AMF and water starvation. On the other hand, in potato plants infected with potato virus Y and inoculated with the AMF Funneliformis mosseae and R. irregularis , improvements in photosynthetic parameters were observed in both healthy and infected plants, although F. mosseae was shown to improve these parameters slightly more [ 38 ].…”

Assessment of the Air pollution tolerance capacity of trees for development of greenery around the industrial area

“…The deterioration of the environment is one of the aforementioned problems. The environment upon which humanity's way of life depends most has been harmed by pollution that man brought about by irrational, unscientific development and mineral extraction (Bhardwaj et al, 2023a;Rai et al, 2013;Singh and Tandon, 2009). Rapid industrialization and urbanization are inevitable dangerous outcomes that have a range of negative consequences on both plant and human societies.…”
