Arya S Nair

Seed priming is a seed enhancement technique to improve the seed germination and seed vigor. It is the process of soaking of seeds in a particular solution having particular osmotic potential for particular duration. Through which seeds absorbs water, cell become elongates, repairing of mitochondria, DNA takes place, and helps to activate enzymes and breakdown the storage materials into energy form for the growth of plant. This technique consists of different methods of treatments like, hydro-priming, halo-priming, hormonal priming, osmo-priming, solid-matrix & bio-priming according to different crops. In this review we discuss about the mechanism of seed priming & its tolerance against abiotic stresses, the changes occurring during the treatment, applications and how to maintain sustainability of agriculture by using priming to improve the livelihood of farmers.
