Morphophysiological responses of red amaranth (Amaranthus tricolor L.) to osmopriming treatment to overcoming salinity stress

Abstract Global climate change induced environmental stress such as salinity significantly impact growth and crop productivity. Red amaranth ( Amaranthus tricolor L.) is a vegetable commodity that has high nutritional value, but its productivity will decrease when grown in saline area. Seed priming one of the pre-planting treatment techniques used to increase plant under unfavourable conditions. Osmopriming where seeds be immersed solution with osmotic potential, PEG (Polyethylene Glycol). The purpose this study was determine morphophysiological response red osmopriming stress. Complete randomized design arrange experiment containing two variables including seed (0, 5% 10% PEG) 50, 100 mM NaCl). Morphophysiological parameters were measured height, number leaves, root length, leaf chlorophyll content, proline oxalic acid content Ca-oxalate crystal density. After 6000 increased leaves length Under Chlorophyll while proline, density decreased on 6000. enhances characters overcome problems cultivating
