Silica nanoparticles as a waste product to alleviate the harmful effects of water stress in wheat.
Drought is a threat to food security and agricultural sustainability in arid and semi-arid countries. Using wasted silica nanoparticles could minimize water scarcity. A controlled study investigated wheat plant physiological and morphological growth under tap-water irrigation (80-100, 60-80, and 40-60% field capacity). The benefits of S1: 0%, S2: 5%, and S3: 10% nanoparticle silica soil additions were studied. Our research reveals that water stress damages the physiological and functional growth of wheat plants. Plant height decreased by 8.9%, grain yield by 5.4%, and biological yield by 19.2%. These effects were observed when plants were irrigated to 40-60% field capacity vs. control. In plants under substantial water stress (40-60% of field capacity), chlorophyll a (8.04 mg g-1), b (1.5 mg g-1), total chlorophyll (9.55 mg g-1), carotenoids (2.44 mg g-1), and relative water content (54%), Electrolyte leakage (59%), total soluble sugar (1.79 mg g-1 fw), and proline (80.3 mol g-1) were highest. Plants cultivated with silica nanoparticles exhibit better morphological and physiological growth than controls. The largest effect came from maximum silica nanoparticle loading. Silica nanoparticles may increase drought-stressed plant growth and production.
期刊介绍:
ACS Applied Electronic Materials is an interdisciplinary journal publishing original research covering all aspects of electronic materials. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrate knowledge in the areas of materials science, engineering, optics, physics, and chemistry into important applications of electronic materials.
