Bibliography: leaves 153-156. / ix, 156 p. : ill. ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / This thesis describes the experiments conducted to determine the mechanisms that cause the decline in shoot Zn concentration and the responses of the wheat plant to Zn deficiency and chlorosulfuron stress. Root tip extension is used as a measure of wheat root growth during exposure to the sulfonylurea herbicide chlorsulfuron. Wheat plants differing in Zn efficiency are grown in HEDTA chelate-buffered nutrient solution in controlled conditions. / Thesis (Ph.D.)--University of Adelaide, Dept. of Plant Science, 1997

Manipulation of dietary zinc produced a different body zinc status in male Japanese quail during 3 weeks of treating period. After intramuscular injection with 8μmol/100g body weight of estradiol-17β, Japanese quail were sacrificed and vitellogenin (phosphoprotein) production was assessed in these birds by analyzing plasma for protein-bound phosphorus concentrations (PBP). Plasma PBP concentrations of estrogen-injected male quails increased from undetectable values for control birds to O.66mg/ml for high-zinc birds and O.42mg/ml for low-zinc birds. About 36% loss of vitellogenin synthesis was associated with the consumption of the zinc-deficient diet. Plasma zinc concentrations also increased on the estrogen injection because of the zinc-binding property of vitellogenin. The extra zinc ions in the plasma were considered to be come from the body zinc pools. Liver as well as other major tissues was believed to act as a reservoir of zinc for egg development but it was not observed that liver was the major source of the extra zinc in the plasma. / Master of Science
