Seed Priming: A Key to Sustainability in Drought Stress
نویسندگان
چکیده
Abiotic stresses spot lights the field crops at all growth phases and results in significant yield losses important crops, endangering safety of world's food supply. Numerous physiological, biochemical, molecular tactics have been examined by crop researchers to battle drought stress/water limiting stress, but current environment, these measures are meager. It is so claimed that plants can be primed various organic inorganic stimulants for exceptional toughness under stressful circumstances. In order confer tolerance, novel seed priming techniques promising research stress biology management. Seed process carefully hydrating seeds with germination pre- germinative metabolic activity continue while radicle's emergence halted. The terms "hydro-priming," "osmo-priming," "halo-priming," "solid matrix priming," "bio-priming," "hormonal priming" refer techniques. will speed up synchronize germination, improve plant stand establishment, raise fertilizer water use efficiency, superior weed suppression effects. This review paper covers physiological biochemical changes through several techniques, Nano-priming its significance sustainable agriculture.

Hormonal priming to overcome drought stress and aging damage in groundnut seed (Arachis hypogaea L.)
Groundnut seed priming was performed with an aqueous solution of gibberellic acid (GA3) (0, 50, 100, and 150 ppm for 18h) and accelerated aging (96 h) was done prior to drought stress (-0.4, -0.6, and -0.8 MPa), then recovered. Investigated traits were germination percentage, mean germination time, germination rate, vigor index, plumule length, radicle length, seedling length, malondialdehyde c...
