英文摘要	There is now a consensus that global warming causes climate change and is a worldwide threat, which presents a great challenge for the 21st century. Arid, semiarid, and tropical regions of the world including Pakistan, where climate change is enhancing salinization and is restricting plant growth and production by reducing nutrient uptake and increasing osmotic stresses. Keeping in view all these interlinked predicted climatic change, present study was aimed to determine the effect of osmopriming withPolyethylene glycol(PEG-4000) forosmotic potential(psi(s) = -0.2MPa), hydropriming, thermopriming on cultivars ofCapsicum annuumL. analyzing germination indices, physiological and biochemical attributes under induced salinity stress of 60 mM and 80 mMsodium chloridechosen from deleterious effect of these concentrations in preliminary screening experiment. Results indicated highest tolerance in the osmoprimed seeds (PEG-4000) to lower salt stress significantly atpchlorophyll "a"(chlo "a"),chlorophyll "a" and "b"ratio (chlo a/b ratio),total chlorophyll content(TCC) andcarotenoid content(CC) resulting less deterioration of photosynthetic pigments whereas; maximumtotal proline content(TPC) (p< .001),superoxide dismutase(SOD), andperoxidase(POD) atp= .01) andascorbate peroxidase(APOX) atp< .05 in hydroprimed seeds reflecting the ability of selected cultivars to resist oxidations. It is concluded that high salinity altered many metabolic processes due to high osmotic potential inside the cell which is considered an alarming situation for the forthcoming climate change in Pakistan and required climate-smart agriculture to lower the negative impact forthcoming salinization, before it might affect global crop production drastically.
