Zinc (Zn) deficiency in corn causes interveinal, light striping or a whitish band beginning at the base of the leaf and extending towards the tip. Analysis of energy reserves in resistant A. gossypii fed on micronutritient-amended plants revealed decreases in the lipid and protein contents of aphids, whereas glycogen and carbohydrate contents showed no response. application (Doncheva et al., 2001). Even at low concentrations Cd is extremely toxic to plants (Clemens and Ma, 2016), but at concentrations 3× above WHO (1996) limits in combination with elevated Zn levels, can result in oxidative stress. Differential toleranc e of plant Differential toleranc e of plant genotypes exposed to zinc toxicity is a more promising approa ch to enrich our understanding of zinc tolerance in plants. articles Accumulation and toxic effects of chromium and zinc in Iris pseudacorus L.

Zn is a microelement present in the human body; there is approximately 2-3 g of Zn in a 70-kg live weight human body. Both Zn and NaCl significantly inhibited growth and induced severe alterations in root morphology. << 2011. Thus,this suggests the possibility of T.erecta usefulness in limiting toxicant induced by environmental heavy metals. 2001. photosynthesis. Excessive absorption of zinc can suppress copper and iron absorption. Zn uptake arises, (Thoresby and Thornton, 1979; Kabata-Pendias and, translocated through both xylem and phloem tissues. /Type /Page Zinc (Zn) is an essential micronutrient for plants and animals. 140:209-224. photosynthetic characteristics of field grown. J. Zinc deficiency causes leaf discoloration called chlorosis tissue of the veins to turn yellow. This review examines the research performed in the past to show how zinc oxide nanoparticles (ZnO-NPs) are influencing the negative effects of abiotic stresses. Incidence of zinc (Zn) toxicity is rare and has not been reported in sweetpotato crops.Cases in other crops have been reported on acid soils high in zinc, or on soilsoverfertilised with zinc fertiliser. Similarly, the contents of total soluble proteins, total free amino acids, lipid peroxidation, and H2O2 and the activities of antioxidative enzymes (SOD, POD, CAT, APX and proline) were significantly enhanced under salinity stress. Calculations indicated that the experimentally determined translocation rates from SO(2)-stressed leaves were lower than were the rates expected on the. Corpus ID: 43385243. /Author Suntioinen, L.
