The Effect of Pre-sowing Treatments with Glomus mosseae and GA3 on the Leaves Physiology of Melia azedarach Seedling

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