Researchers are very concerned about addressing or managing the growing problem of global warming or climate change. Global warming is caused by greenhouse gases, of which carbon dioxide (CO2) alone contributes 60%. By absorbing carbon dioxide (CO2) during photosynthesis and naturally storing it as biomass, trees serve as a sink for CO2 because trees have the ability to store carbon and can lessen the effects of climate change and global warming, planting trees or restoring forests may be a solution to this growing problem. This review paper can be helpful since it discusses the interaction between arbuscular mycorrhizal fungi (AMF) and the roots of trees, which benefits the plant for better germination and growth. dormancy of seeds or a delay in growth can be identified as a disadvantage in a plantation program. With the hope that this information would advance the field of research, we have concentrated on mycorrhizal association and its impact on different species of trees in this work. It can be useful for tree species that have lower biomass or slower growth.

Melia azedarach, a versatile tree belonging to the Meliaceae family, presents a significant challenge in achieving successful seed germination for forest plantations. The robust nature of Melia azedarach seeds necessitates pre-treatments to overcome physical barriers and enhance water absorption. Natural ecosystems often benefit from the symbiotic relationship between Arbuscular mycorrhizal (AM) fungi and plant roots, which promotes survival and growth. This study examined the impact of Glomus mosseae-inoculated soil on Melia azedarach seeds treated with pre-sowing techniques at the Nursery of the Forestry Department, CCSHAU, Hisar in 2019. Glomus mosseae was sown at a rate of 400–500 sporocarps per kg of soil, and its influence was evaluated in terms of physiological parameters, survival rate, root colonization percentage, and sporocarp count. Each replication of the experiment involved 250 seedlings and was repeated five times. Results demonstrated that soils inoculated with Glomus mosseae and treated with gibberellic acid at 200 ppm for 24 hours prior to sowing exhibited significantly higher physiological parameters (chlorophyll and carotenoid content, photosynthesis rate, transpiration rate, and stomatal conductance), survival percentage, root colonization percentage, and sporocarp count (per 100 g of soil). Therefore, the combined use of Glomus mosseae and gibberellic acid at 200 ppm for 24 hours is recommended to enhance physiological growth and plant survival in Melia azedarach.
