摘要

Seed priming is a pre-germination treatment recognized for its potential to enhance seedling emergence, growth, and stress tolerance. This review delves into key seed priming techniques, viz., hydropriming, nanopriming, chemopriming, biopriming, and hormone priming and their associated physiological, biochemical, and molecular effects. Priming induces stress memory by upregulating key genes involved in gibberellic acid biosynthesis, photosynthesis, antioxidant defense, and polyamine metabolism, enhancing tolerance to salinity and drought stresses. Adverse germination temperatures impair vital physiological and biochemical processes, underscoring the role of priming in mitigating such effects. Its versatility, cost-effectiveness, and less labor-intensiveness make seed priming a practical approach to improve germination, crop establishment, yield, and stress resistance in modern agriculture. Understanding the molecular and physiochemical mechanisms underlying seed priming is crucial for identifying early markers of abiotic stress tolerance, enabling targeted crop selection and improved priming protocols to strengthen sustainable strategies for yield stability and food security.
