“…Collectively, plants employ many tactics to counteract the negative effects of salt by collecting a range of osmolytes and antioxidant enzymes. These substances serve to maintain the stability of proteins and membranes by preserving the osmotic balance and preventing the generation of harmful ROS [ 66 ]. In the present investigation, the enzymatic activities of POX, CAT, SOD, APX, and GR were enhanced with a progressive increase in salinity stress, counterbalancing the detrimental effects generated by the ROS.…”

Salinity is one of the most significant abiotic stress that affects the growth and development of high-value tree species, including sandalwood, which can also be managed effectively on saline soils with the help of suitable host species. Therefore, the current investigation was conducted to understand the physiological processes and antioxidant mechanisms in sandalwood along the different salinity gradients to explore the host species that could support sandalwood growth in salt-affected agro-ecosystems. Sandalwood seedlings were grown with ten diverse host species with saline water irrigation gradients (ECiw~3, 6, and 9 dS m−1) and control (ECiw~0.82 dS m−1). Experimental findings indicate a decline in the chlorophyll content (13–33%), relative water content (3–23%), photosynthetic (27–61%) and transpiration rate (23–66%), water and osmotic potential (up to 137%), and ion dynamics (up to 61%) with increasing salinity levels. Conversely, the carotenoid content (23–43%), antioxidant activity (up to 285%), and membrane injury (82–205%) were enhanced with increasing salinity stress. Specifically, among the hosts, Dalbergia sissoo and Melia dubia showed a minimum reduction in chlorophyll content, relative water content, and plant water relation and gas exchange parameters of sandalwood plants. Surprisingly, most of the host tree species maintained K+/Na+ of sandalwood up to moderate water salinity of ECiw~6 dS m−1; however, a further increase in water salinity decreased the K+/Na+ ratio of sandalwood by many-fold. Salinity stress also enhanced the antioxidative enzyme activity, although the maximum increase was noted with host plants M. dubia, followed by D. sissoo and Azadirachta indica. Overall, the investigation concluded that sandalwood with the host D. sissoo can be successfully grown in nurseries using saline irrigation water and, with the host M. dubia, it can be grown using good quality irrigation water.

Arbuscular Mycorrhizal Fungi in Agriculture - New Insights

Climate change and agricultural practices like unrestricted utilization of insecticides especially fertilizer and pesticides have amplified the effects of inanimate stress on the productivity of crops and degraded the environment. The need of the hour is to adopt eco-friendly crop management techniques, including the usage of arbuscular mycorrhizal fungi (AMF). AMFs are frequently referred to as bio-fertilizers. Mycorrhiza improves the movement and absorption of nutrients from soils, thereby limiting the demand for artificial fertilizers and avoiding the accretion of nutrients in soil. Reduced fertilizer use reduces the effects of fertilizer runoff and leaching on water quality and serves as a cost-effective method for farmers. Inanimate stressors (such as salt, drought, heat, cold, and mineral shortage) have emerged as the most serious dangers to global agricultural productivity. These stresses induce ion toxicity nutritional imbalance, hormonal inequalities which in turn influence plant growth and development, maturity, productivity etc. Some beneficial microorganisms, such as mycorrhizal fungi, live in mutualistic association with the roots of host plant in the rhizospheric region. Mycorrhiza significantly improves host plant resilience to a variety of animate and inanimate stresses. This chapter emphasizes the relevance of mycorrhizal fungi in stress reduction and their beneficial impacts on plants’ production, growth and enlargement.
