Salinity causes an excessive influx of Na + in roots and leaves, which ultimately leads to K + efflux, thus causing K + deficiency in plants (Demidchik et al., 2014)., On the other hand, foliar fertigation lowered Na + uptake, which simultaneously enhanced the uptake of K + contents in cells (Table 2). The high contents of P and Ca in bones and soils close to bones were a source of these elements for plants, indicated by a high density of fine roots. /Resources 30 0 R Exposure to elevated levels of zinc and zinc-containing compounds can result in a variety of adverse effects in the gastrointestinal, hematological, and respiratory systems along with alterations in the cardiovascular and neurological systems of humans. 12 0 obj The objective of this work was to determine the effect of the edaphic and foliar application of zinc sulphate on the nutrient content, bioactive compounds, and antioxidant capacity of cowpea beans (Vigna unguiculata L.

Using portable X-ray fluorescence spectrometry, we determined the elemental composition of sandy necrosols from a Corded Ware Culture (ca 2800-2500 BCE) graveyard, Chudeřín, Czech Republic. /MediaBox [0.0 0.0 629.0 799.0] for plants or animals, yet are toxic under certain conditions (Wallace, Romney, Alexander, and Kinnear, 1977). %PDF-1.4 << (Pedler et al., 2004; Giuffré et al., 2012). /Type /Page endobj /Type /Pages INTRODUCTION Both ericaceous and ectomycorrhizal fungi can ameliorate metal toxicity to the associated higher plants (Bradley, Burt & Read, 1981, 1982; Brown & By analyzing this information, plant scientists can de-termine the nutrient need of a given plant in a given soil. The inadequate dietary intake of this micronutrient constitutes a public health problem [8], which affects 17.3% of the world population, making it the fifth leading health risk factor in developing countries and the eleventh worldwide [9]. Baltic Sea. /Parent 2 0 R consumed. /Parent 2 0 R Cu levels in T. caerulescens grown with 10 μ m Cu2+ remained in the nonaccumulator range (<50 ppm), and most individuals were as sensitive toward Cu as the related nonaccumulator Thlaspi fendleri . Mild Zn deficiency depressed shoot but enhanced root DM and this change was almost paralleled by P distribution. Data were analyzed using multivariate analysis showing a primary separation in two groups: eight sites with high contents of one or more of the analized heavy metals and the second group with lower levels of heavy metals. endobj To better appraise the potential benefits arising from optimum Zn nutrition, in the present review we discuss the role of Zn in plants under drought stress. /Creator >> endobj Deficiency of major micronutrients {calcium (Ca), zinc (Zn) and iron (Fe)} is common in sorghum which creates some health problems in livestock. /Resources 36 0 R /Contents 37 0 R Approximately one month of intensive monitor-ing activities were carried out and quality analyseswere conductedonthreematricescomprising the pilot H-CW:water, biomass (Canna indica,Typha latifolia), and volcanic gravel substrate. /DR 20 0 R The pancreas accumulate significantly more Zn than liver and spleen at 25, Lead intoxication may initiate many disorders in humans and animals. The cultivation of a large number of crops in the contaminated environment is a main concern of environmentalists in the present time. The salt stress resulted in a reduced biological yield associated with a decrease in chlorophyll pigment, while a significant enhancement in Na⁺ and Zn²⁺ was observed under salinity stress. Resistant cotton aphids fed on micronutritient-amended plants showed significantly reduced fecundity, longevity, and reproductive periods, and a 1.7-fold reduction in pirimicarb LC50 compared with those fed on control plants. Cadmium(II). Although the presence of all elements can be linked to underlying geology and geochemistry specific to each site, evidence of anthropogenic cause was also evident at both sites. Braz. Zinc is commonly involved in the expression of genes encoding antioxidative enzymes such as APX, ... Metal bioaccumulation in macrophytes hypogeal organs Pre and Post semi-synthetic stormwater runoff treatment in the pilot hybrid-CW system from December 2018 to January 2019, in Catania, Italy. For omnivorous adults, more than one-third of dietary zinc can be provided by flesh foods, whereas for vegetarians, plant-based foods are the major dietary source. endobj >> It can also cause a loss of appetite, diarrhea and impair immune function. endobj /Parent 2 0 R Nat.

Therefore, the study was conducted during summer 2018 at Agronomic Research Farm, College of Agriculture, University of Sargodha Pakistan to evaluate the impact of calcium (Ca), zinc (Zn) and iron (Fe) bio-fortification on yield and quality of forage sorghum under field conditions.
