ABSTRACT
It is crucial to prioritize research focused on the resilience of certain tree varieties used in reforestation or for combating desertification under germination conditions and environmental stresses. This approach is vital to enhance the productivity and sustainability of these tree species. The objective of this study was to evaluate the ability of this variety to sustain growth and yield under various environmental condition, particularly drought, extreme temperatures, and saline stress. Close monitoring of plant growth is essential, along with measuring a range of physiological and agronomic parameters such as germination, soil structure adaptation, survival rates, and nutrient content. Furthermore, advanced techniques are indispensable for understanding the mechanisms of germination and resistance to various environmental stressors. These may include identifying physio morphological modifications that contribute to stress tolerance as well as metabolic pathways involved in plant responses to adverse environmental conditions. The Results from the germination phase revealed a highly significant germination speed, with a germination rate of 75%. Regarding responses to saline stress at different concentrations (25, 50, and 75%), batch 03 showed the best performance. There, it can concluded that a saline concentration of 25% represented the peak tolerance level for this variety. The findings of these studies could be utilized to select and develop new, more stress-resistant varieties, potentially significantly improving food security and mitigating the effects of climate change on agriculture.
