Analysis Of Black Point In Wheat, J M. Wilson
Analysis Of Black Point In Wheat, J M. Wilson
Technical Bulletins
Fungal staining (black point) of wheat can reduce the quality of grain. The most serious problem is a discolouration of products. Discolouration is a consequence of infection by microorganisms. The most likely cause in Western Australia is a species of the common fungus Alternaria. Infection and discolouration occur between flowering and grain maturity, and the optimum environmental conditions are probably consecutive days of high relative humidity together with warm temperatures.
Effects Of Elevated Co2 On Crop Growth Rates, Radiation Absorption, Canopy Quantum Yield, Canopy Carbon Use Efficiency, And Root Respiration Of Wheat, Oscar A. Monje
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Wheat canopies were grown at either 330 or 1200 μmol mol-1 CO2 in sealed controlled environments, where carbon fluxes and radiation interception were continuously and nondestructively measured during their life cycles. The effects of elevated CO2 on daily growth rates, canopy quantum yield, canopy and root carbon use efficiencies, and final dry mass were calculated from carbon flux measurements in an open gas exchange system. Dry biomass at harvest was predicted from the gas exchange data to within ± 8%. The greatest effect of elevated CO2 occurred in the first 15d after emergence; however, several physiological …

Production Of High-Value Wheats : One Sustainable Answer To The Cost:Price Squeeze, Wal Anderson, Alan Peggs, Doug Sawkins
Journal of the Department of Agriculture, Western Australia, Series 4
Farmers and scientists alike over the past decade have sought to address the declining terms of farm trade (the cost.price squeeze) by increasing wheat yields in ways that will ensure both their economic and ecological survival. Nevertheless, costs have continued to increase as a proportion of the value of the product.
Many farmers have increased their wheat yields substantially and the industry as a whole is more conscious of the quality of its product.
Over the past 10 years or more there has been intense interest in, and considerable adoption of. conservation farming techniques such as minimum tillage, residue retention, …
