Malnutrition is mainly caused by iron and zinc micronutrient deficiencies affecting about half of the world's population across the globe. Biofortification of staple crops is the right approach to overcome malnutrition and enhance nutrient contents in the daily food of humans. This study aimed to evaluate the role of foliar application of iron and zinc in treated soil on various growth characteristics, quality, and yield of wheat varieties. Plants were examined in the absence/presence of , and iron and zinc micronutrients in both optimal and high-stress conditions. Although the symbiotic association of and common wheat is utilized as an effective approach for wheat improvement because of the dynamic growth promoting the ability of the fungus, this association was found tremendously effective in the presence of foliar feeding of micronutrients for the enhancement of various growth parameters and quality of wheat. The utilization of this approach positively increased various growth parameters including spike length, grain mass, biomass, harvest index, and photosynthetic pigments. The beneficial role of in combination with zinc and iron in stimulating plant growth and its positive impact on the intensities of high molecular weight glutenin subunits (HMW-GS) alleles make it an interesting approach for application in eco-friendly agricultural systems. Further, this study suggests a possible alternative way that does not merely enhances the wheat yield but also its quality through proper biofortification of iron and zinc to fulfill the daily needs of micronutrients in staple food.
营养不良主要是由铁和锌等微量营养素缺乏引起的,全球约有一半人口受其影响。主粮作物的生物强化是克服营养不良并提高人类日常食物中营养成分的正确途径。本研究旨在评估在处理过的土壤中叶面喷施铁和锌对小麦品种各种生长特性、品质和产量的作用。在有无丛枝菌根真菌(AMF)以及铁和锌微量营养素的情况下,在最佳和高胁迫条件下对植株进行了检测。尽管由于真菌具有促进生长的动态能力,AMF与普通小麦的共生关系被用作小麦改良的有效方法,但发现这种共生关系在叶面喷施微量营养素的情况下对提高小麦的各种生长参数和品质极为有效。采用这种方法能积极提高包括穗长、粒重、生物量、收获指数和光合色素在内的各种生长参数。AMF与锌和铁结合在刺激植物生长方面的有益作用及其对高分子量谷蛋白亚基(HMW-GS)等位基因强度的积极影响,使其成为一种适用于生态友好型农业系统的有趣方法。此外,本研究提出了一种可能的替代方法,即通过对铁和锌进行适当生物强化,不仅提高小麦产量,还能提高其品质,以满足主食中微量营养素的日常需求。
