Foliar exposure of zinc oxide nanoparticles improved the growth of wheat (Triticum aestivum L.) and decreased cadmium concentration in grains under simultaneous Cd and water deficient stress

Green Synthesized Metal Oxide Nanoparticles Mediate Growth Regulation and Physiology of Crop Plants under Drought Stress

“…Foroutan et al [ 90 ] showed that ZnONPs treatment could significantly increase drought tolerance in distinct M. peregrina species during water deficit conditions by increasing the antioxidant polyphenol oxidase (PPO) and peroxidase (POD) activities and osmoprotectant content ( Table 2 ). In comparison to the control, foliar application of ZnONPs reduced oxidative stress and increased leaf SOD and POD activities [ 88 ]. Increased antioxidant enzyme activity and decreased oxidative stress indicators in wheat leaves may represent a stress tolerance mechanism under stressful conditions [ 88 ].…”

“…In comparison to the control, foliar application of ZnONPs reduced oxidative stress and increased leaf SOD and POD activities [ 88 ]. Increased antioxidant enzyme activity and decreased oxidative stress indicators in wheat leaves may represent a stress tolerance mechanism under stressful conditions [ 88 ]. SOD assists in the detoxification of superoxide (O 2 − ) under drought-induced oxidative stress by activating dismutation reaction and converting it to O 2 and H 2 O 2 .…”

Biogenic ZnO Nanoparticles Synthesized Using a Novel Plant Extract: Application to Enhance Physiological and Biochemical Traits in Maize

“…Several studies have shown that NPs can stimulate plant germination, photosynthesis, and development [ 5 , 7 , 14 , 15 ]. Moreover, biogenic ZnO-NPs have been shown to increase crop resistance to abiotic stresses such as salinity, drought or toxic metals [ 16 ]. Plant extracts efficacy in the biogenic synthesis of ZnO-NPs has been documented on a wide variety of molecules they contain.…”

Biofortification: Zinc Enrichment Strategies in Crops

“…Wheat (Triticum aestivum) Soil, Foilar, Priming, Soil+Foliar Taban et al [38], Dhawial et al [39], Pavia et al [40], Liu et al [41], Akça [20] Maize (Zea Mays) Soil, Foliar, Priming Liu et al [42], Zhang et al [43], Martínez-Cuesta et al [44] Rice (Oryza Sativa) Soil, Soil+Foliar Özcan [45], Özcan et al [46], Özcan [47], Phuphong et al [48], Grija Veni et al [49] Lettuce (Lactuca sativa) Foliar Tang et al [50], Gao et al [51], Adrees et al [52] Onion (Allium cepa) Foliar Rafie et al [53] Common bean (Phaseolus vulgari) Foliar+Priming Tabesh et al [54] The source, method, time, and rates of Zn applications in agricultural biofortification should be well known and developed [5]. Zinc is usually applied to plants in the form of ZnSO 4 or synthetic chelates [20,37,38,57] (Shuman 1998, Broadley et al 2007).…”

“…Biofortification is an effective and inexpensive method of increasing and improving the microelement content of foods, which are of great importance for the health of the human population especially in developing countries but needs special attention in the way of source of nutrients and effects on the environment [37]. Application of zinc in soil and/or foliar offers a quick solution to increase Zn concentration in cultivated plants [20,[38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54] (Table 1). Although zinc application is an effective way to increase the yield and microelement concentration of crops, many producers in the world (especially in developing countries) [55].…”
