Agriculture, Journal Year: 2020, Volume and Issue: 10(9), P. 396 - 396

Published: Sept. 7, 2020

Drought stress affects plant growth and development by altering physiological biochemical processes resulting in reduced crop productivity. Zinc (Zn) is an essential micronutrient that plays fundamental roles resistance against the drought regulating various molecular mechanisms. Under stress, Zn application improves seed germination, water relations, cell membrane stability, osmolyte accumulation, stomatal regulation, use efficiency photosynthesis, thus significantly better performance. Moreover, interacts with hormones, increases expression of proteins stimulates antioxidant enzymes for counteracting effects. To appraise potential benefits arising from optimum nutrition, present review we discuss role plants under stress. Our aim to provide a complete, updated picture order orientate future research directions on this topic.

Plants, Journal Year: 2021, Volume and Issue: 10(2), P. 421 - 421

Published: Feb. 23, 2021

Water shortage and salinity are major challenges for sustaining global food security. Using nutrients in the nano-scale formulation including zinc oxide nanoparticles (ZnO NP) is a novel fertilization strategy crops. In this study, two field-based trials were conducted during 2018 2019 to examine influence of three ZnO NP concentrations (0, 50, 100 ppm) eggplant grown under full irrigation (100 crop evapotranspiration; ETc) drought stress (60% ETc). Plant growth, yield, water productivity (WP), physiology, biochemistry, anatomy responses evaluated. Drought significantly decreased membrane stability index (MSI), relative content (RWC), photosynthetic efficiency, thus hampered growth yield. contrast, exogenous water-stressed resulted increased RWC MSI associated with improved stem leaf anatomical structures enhanced efficiency. Under stress, supplementation 50 ppm characteristics fruit yield by 12.2% 22.6%, respectively, compared fully irrigated plants nonapplied NP. The highest (WP) was obtained when 60% ETc foliarly treated or NP, which led 50.8–66.1% increases WP nontreated plants. Collectively, these findings demonstrated that foliar spraying gives utility alleviating effects on cultivated saline soil.
