Jasmonate-Mediated Mitigation of Salinity Stress During Germination and Early Vegetative Development in Hemp.

ABSTRACT: Climate change and soil salinization threaten crop productivity, particularly affecting salt-sensitive species like hemp (Cannabis sativa L.), which is gaining importance in sustainable agriculture and bioeconomy. Jasmonates (JAs) offer promising potential for enhancing plant abiotic stress tolerance. Given hemp's inherently low salt tolerance and limited data on JAs-mediated responses, we investigated salinity tolerance JAs modulation using methyl jasmonate (MeJA; 0.001-0.01 mM) and the JAs-biosynthesis inhibitor mefenamic acid (MEF; 0.01-0.1 mM) applied via seed priming or foliar treatment in factorial experiments with NaCl concentrations of 0.05-0.3 M. We demonstrate that MeJA and MEF differentially modulate responses of Henola hemp variety to salt stress during germination and s
