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...

Osmotic and oxidative stress responses to iso-osmotic (-0.4 Mpa) NaCl, PEG-6000 and mannitol stress were studied in 15-day old plants of three potato cultivars viz. ‘Kufri Kufri Bahar’ ‘Jyoti’ and ‘Chandramukhi’. After 2-weeks of treatment, plants were analyzed for biochemical and physiological determinants of stress. Relative water content (RWC) and membrane damage rate (MDR) were significantl...

Drought is one of the most detrimental environmental stressors to plants with potential decrease crop yields and affect agricultural sustainability. Native bacteria beneficial traits enhance plant growth help avoid reverse effects drought in a greater extent. In present study, we aimed ( i ) isolate drought-tolerant Bacillus isolates from rhizosphere soil wheat grown at different locations Jais...

silicon is known to ameliorate the deleterious effects of drought on plant growth. we evaluated growth of wheat (triticum aestivum l. cv. chamran) under water-deficit stress induced by polyethylene glycol as affected by si application. in this article, the effects of si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (rwc), electrol...

Polyethylene glycol (PEG) can be used to mimic osmotic stress in plant tissue cultures to study mechanisms of tolerance. The aim of this experiment was to investigate the effects of PEG (M.W. 6000) on embryogenic callus of Medicago truncatula. Leaf explants were cultured on MS medium with 2 mg L-1 NAA and 0.5 mg L-1 BAP for 5 months. Then, calli were transferred to the same medium further suppl...

Two barley cultivars were subjected to water stress by immersing their root system in PEG 6000. The relative water content (RWC) of the leaves fell under these conditions and membrane disorganisation was evidenced by the injury index data. The two genotypes differed in their leaf water content under the applied stress. The aim of this work was to examine the relationship between proline accumul...

Drought, salinization and heavy metal pollution of soils are main stress factors with an increasing impact on the deterioration soil quality, yield crop quality. Seed priming shows good results in improving seed germination, seedling growth plant development. Proline (Pro) metyl jasmonate (MeJA) show stimulating activity help plants overcome stress. The study investigated effect Pro, MeJA hydro...

Drought stress is a major factor in reduce growth, development and production of plants. Stress was applied with polyethylene glycol (PEG) 6000 and water potentials were: zero (control), -0.15 (PEG 10%), -0.49 (PEG 20%), -1.03 (PEG 30%) and -1.76 (PEG40%) MPa. The solutes accumulation of two maize (Zea mays L.) cultivars -704 and 301were determined after drought stress. In our experiments, a hi...
