Plant Growth Regulators for Abiotic Stress Alleviation in Spice Crops: A Critical Appraisal of Mechanisms, Evidence Quality and Translational Gaps
Spice crops occupy a minor share of global cropland yet underpin export earnings, smallholder livelihoods and food quality across the tropics and subtropics. Their production systems are unusually exposed to water deficit, soil salinity and temperature extremes, and their value depends on secondary metabolites whose ac...
