Abstract :
Considering the high salinity of soils in arid regions and the sensitivity of Prosopis Koelziana seedlings to this stress, the species faces the threat of extinction. Its vegetative communities are also at risk of deterioration. In recent years, the utilization of cold plasma to enhance germination and resistance to various stresses in plants has been emphasized. This study examines the impact of priming Prosopis Koelziana seeds using cold plasma under varying conditions and influenced by different gases and voltages, aiming to improve germination and plant establishment in salinity-stressed environments. This method could be instrumental in conserving this desert species. To investigate the effects of salinity on the Prosopis Koelziana plant, a completely randomized factorial experiment was conducted with three replications. The experimental treatments included various salinity concentrations (100, 200, 300, and 400 millimolar), different plasma priming durations, varying plasma voltages and the use of different gases. Data showed that no germination was observed in 300 and 400 mM salt concentrations, so they were excluded in the following experiment stages. Furthermore, the 100 and 200 mM salt concentrations were considered. In this experiment, the best time for plasma treatment was 6, 8, and 10 minutes, best voltage is voltages 10 and the best gas was helium. The data from this study showed that cold plasma treatment for a specific duration, specifically 8 minutes with helium gas, can have positive biological effects on the germination of the valuable Prosopis Koelziana plant.
