The effect of soil acidity on root and rhizosheath development in wheat and barley seedlings was investigated in an acid Ferrosol soil to which various amounts of lime (CaCO3) were applied to modify soil Al concentrations (pH (CaCl2): 4.22 to 5.35 an

Barley (Hordeum vulgare L.), genetically modified with the Al(3+) resistance gene of wheat (TaALMT1), was compared with a non-transformed sibling line when grown on an acidic and highly phosphate-fixing ferrosol supplied with a range of phosphorus co

To understand whether genotypic variation in root-associated phosphatase activities in wheat impacts on its ability to acquire phosphorus (P), various phosphatase activities of roots were measured in relation to the utilization of organic P substrate

This study examined the potential of cover crops (fodder rape, oats, and white lupin) to improve phosphorus (P) availability in a high P-fixing Red Ferrosol soil at Robertson, New South Wales. Of particular interest was a fourth cover crop that consi

To assess the effectiveness of manipulating citrate metabolism with the aim of increasing citrate efflux from roots, we generated transgenic tobacco (Nicotiana tabacum L.) lines that either overexpressed mitochondrial citrate synthase (EC 4.1.3.7) ac

Canola, Indian mustard, Linola and wheat were grown in field experiments for two seasons in the contrasting environments of Junee and Condobolin, NSW, to investigate the effects of nitrogen (N) fertilizer on N uptake by the crops, the removal of N in

We investigated (1) the effect of constant and altered inorganic phosphate (P i ) supply (1-100 mmol m -3 ) on proteoid root production by white lupin (Lupinus albus L.); and (2) the variation in citrate efflux, enzyme activity and phosphate uptake a

Above-ground primary production and nutrient fluxes (N and P) were investigated for two species of seagrass, Posidonia sinuosa Cambridge et Kuo and P. australis Hook. f. from Warnbro and Cockburn Sounds over an annual cycle, at sites ranging in depth

Canola (Brassica napus) was grown under dryland conditions in field experiments at Greenethorpe (1988) and Canowindra (1989) in the cereal belt of New South Wales to determine (1) the response of the crop to nitrogen (N) fertilizer when grown late in
