Prediction Of Zinc Deficiency In Navy Beans (Phaseolus Vulgaris) By Soil And Plant Analyses, J. D. Armour, A. D. Robson, G. S.P. Ritchie
Prediction Of Zinc Deficiency In Navy Beans (Phaseolus Vulgaris) By Soil And Plant Analyses, J. D. Armour, A. D. Robson, G. S.P. Ritchie
Food Science and Nutrition
Navy beans (Phaseolus vulgaris cv. Gallaroy) were grown with 7 rates of zinc (Zn) in a Zn-deficient gravelly sandy loam in a glasshouse experiment. The plant shoots were harvested 31 days after sowing and the Zn concentration in each of 4 plant parts (YL, young leaf; YOL, young open leaf; YFEL, youngest fully expanded leaf; and whole shoots) was related to the fresh weight of the shoots. The critical Zn concentrations (mgtkg) in the plant parts determined by the 2 intersecting straight lines model were 21.1 for YL (r2 = 0.66), 17.1 for YOL (r2 = 0.83), …
Extractable Zinc In Particle Size Fractions Of Soils From Western Australia And Queensland, J. D. Armour, G. S.P. Ritchie, A. D. Robson
Extractable Zinc In Particle Size Fractions Of Soils From Western Australia And Queensland, J. D. Armour, G. S.P. Ritchie, A. D. Robson
Food Science and Nutrition
The zinc (Zn) content of particle size fractions of 12 mainly Zn deficient soils was measured by extraction with three contrasting extractants. The soils, which ranged from sands to a black earth, were from Western Australia and Queensland and particle size fractions (clay, silt, fine sand, coarse sand) were obtained by sieving and sedimentation after ultrasonification of soil suspended in deionized water. The extractants were concentrated HNO3/H2SO4/HClO4 (acid extractable or AE-Zn), DTPA and 0.002 M CaCl2. For each extractant, Zn contents of the fractions and whole soils were correlated with organic …
Zinc Adsorption By A Lateritic Soil In The Presence Of Organic Ligands, P. Chairidchai, G. S. P. Ritchie
Zinc Adsorption By A Lateritic Soil In The Presence Of Organic Ligands, P. Chairidchai, G. S. P. Ritchie
Food Science and Nutrition
Zinc adsorption by a lateritic podzolic soil was measured in the presence of 0 to 3 mmol/litre of acetate, oxalate, citrate, tricarballylate, salicylate, or catechol, or 0 to 3 mmolc/litre of humate. Zinc remaining in solution was measured by atomic absorption spectrometry after shaking the soil for 17 h at a soil/liquid ratio of 1:5 in a 0.003 mol/litre KCl solution containing 0 to 500 μmol/litre Zn and the ligands. In the absence of organic ligands, more than 95% of the zinc was adsorbed. The amount of adsorption was linearly correlated with pH and the concentration of ZnOH …

Annual Variation Of Estuarine And Oceanic Oyster Crassostrea Virginica Gmelin Hemocyte Capacity, William S. Fisher, Marnita M. Chintala, Mark A. Moline
Annual Variation Of Estuarine And Oceanic Oyster Crassostrea Virginica Gmelin Hemocyte Capacity, William S. Fisher, Marnita M. Chintala, Mark A. Moline
Biological Sciences
Defense-related hemocyte activities of American oysters Crassostrea virginica Gmelin from an oceanic and an estuarine habitat were monitored from spring to winter of 1987 at a constant temperature (15 °C). The ability of cells to spread to an ameboid shape in vitro at ambient salinity and after an acute change in salinity was much reduced from late spring to early fall. This summer-stress period was also indicated by laboratory experiments. Stress may have been due to high water temperatures but spawning efforts may have also contributed. Reduced hemocyte activity occurred at a time when infections by two major oyster parasites …
