Abstract
Due to its potential to improve seed germination and early seedling development, "seed priming" has garnered attention recently. This review article covers seed priming systems, their processes, and their many crop production purposes. Seed priming and its importance in seed performance are discussed. Seed priming methods include osmotic, hydro-, hormonal, and microbiological. Each technique is thoroughly detailed, including its procedures, requirements, and pros and cons. The molecular, physiological, and biochemical changes and priming substance-seed interactions of seed priming are examined. The article also discusses seed priming's benefits for stress tolerance, seed germination, seedling vigour, and sustainable agriculture. Most seed treatments use seed imbibition, which allows seeds to germinate but prevents radicals from reaching the seed coat. Dry, desiccation-resistant seeds can be stored until planting. Priming accelerates and synchronises future germination, and early seedlings from primed seeds are often more robust and resistant to abiotic stressors. Progressive farmers that want to boost agricultural productivity would benefit from this technology. This article discusses seed priming methods, mechanisms, and usage in various agricultural situations to boost crop productivity and seed performance.
