WebFoliar-sprayed NPs mainly enter the leaves through stomata and are transported to different plant parts via apoplastic and symplastic pathways. Foliar NPs enhance defenses and resistance against pests and diseases and improve the yield and quality of crops. However, the mechanisms of damage caused by foliar NPs need further elucidation. Web1988]. However, the efects of abiotic factors on nutrient uptake are rarely unequivocal or consistent and are too diverse. In addition, uptake may depend on the environmental conditions or form of the limiting nutrient prior to uptake [ Dortch et al., 1991; Borchardt et al., 1994]. [Cembella et al. (1984) and Ahlgren (1988)] talks on the complex interactions …
