Catalogue: GRDC Final Reports
The rapid, early phase of non-PPO darkening was strongly correlated with, and predicted by, protein content... Non-PPO darkening can be measured with small-scale methods suited to processing large numbers of samples and a major component of this darkening can be predicted simply from grain or flour protein content... Stage 1, an initial rapid darkening in the first two hours, Stage 2 an intermediate stage lasting a further 2 hours during which the rate of darkening slowed, and Stage 3 - lasting for the remainder of the experimental time period and beyond in which darkening was slower but linear over time...

Aphid damage to canola - not all cultivars are equal Fran oise A. Berlandier and Christiaan Valentine, Department of Agriculture, Western Australia.. Oil concentration can be increased either by increasing the amount of oil or by reducing the amount of protein and/or residue in the seed... On a seed basis, there is an amount of protein already in the seed before oil accumulation begins (Hocking and Mason 1993)...

Relationship between growth stage and accumulated uptake of nitrogen by a wheat crop, expressed as a percentage of the total uptake... Optimising N supply is difficult in western regions given the highly variable seasons. Excessive application of N may increase water use early in the growing season leading to greater water stress during flowering and grain fill, resulting in poor grain set or shrivelled grain... There was no significant effect of N rate on grain yield but the effect on protein was significant with protein increasing with rates of applied N. As for the sowing time trial, there was a negative correlation between grain yield and grain protein concentration, and Gregory did not differ from other varieties...

Excessive application of N may increase susceptibility of the crop to disease and increase water use early in the growing season whereas insufficient application may limit grain yield, grain protein and subsequent profitability... As part of the GRDC funded VSAP project, five nitrogen use efficiency trials were conducted in 2011 at Trangie, Condobolin, Parkes, Coonamble and Spring Ridge, as well as a sowing time trial at Trangie, with these trials used in this paper to assess the grain yield and grain protein concentration of several commercial wheat varieties... N application increased the protein of all the varieties, with protein increases being recorded up to 160 kg/ha of applied N...
