Background and Aims Yeast autolysis is understood to be primarily responsible for giving traditional method sparkling wines complex developed aromas. The contribution from ageing the wine itself, however, less well-established. This study aimed determine of products compounds associated with oxidation in Vitis vinifera L. Chardonnay Pinot Noir over 24 months. Methods Results base were tiraged, or aged without primary lees. Volatile composition analyses (HS-SPME/GC/MS GC/MS/MS) conducted at...
Grapevine leaves infected with powdery mildew are a source of inoculum for fruit infection. Leaves emerging on single primary shoot V itis vinifera cv. C abernet S auvignon were exposed to average glasshouse temperatures 18°C (0·23 emerging/day) or 25°C (0·54 emerging/day). All 8–10 shoots approximately 20 each inoculated E rysiphe necator conidia assess disease severity after 14 days in the glasshouse. Two photosynthetic ‘source’ per remaining treated CO 2 identify, by autoradiography, leaf...
The aim of this preliminary study was to identify potential colour components, volatile and sensory attributes that could discriminate Pinot noir wines from five Australian winegrowing regions (Adelaide Hills, Yarra Valley, Mornington Peninsula, Northern Southern Tasmania). analysis consisted the Pivot© Profile method performed by wine professionals. A headspace solid-phase microextraction-gas chromatography-mass spectrometry used quantify multiple compounds, while Modified Somers for...
We tested the hypothesis that lengthening duration between terminal spikelet stage of development and anthesis (referred to here as construction-phase duration, CPD) will increase yield per unit area in wheat (Triticum aestivum L.). Field experiments were undertaken at 17 sites across high-rainfall zone south-eastern Western Australia 2014 2015. In total, 205 genotypes grown. Genetic material included a set near-isogenic lines (NILs) varying photoperiod vernalisation alleles; commercial...
Long season, winter-type canola cultivars have the potential for significantly higher yields than short-season, spring-type canola, yet until recently, breeding of new in Australia has focussed on canola. This been to accommodate typically drier, warmer conditions across Australian cropping belt where long-season varieties do not perform well due delayed flowering and risk water-stress during grain fill. However, as continues expand into High Rainfall Zone (500–900 mm, HRZ), breeders become...
Abstract Total functional leaf area is a key factor in determining crop yield. A nonlinear mixed‐effects model was employed to estimate growth responses for individual leaves using repeated measures of lamina length ≥30 mm, the absence disease. Resulting curves make allowances for, and allow assessment of, variability. The major source variability identified as differences thermal time required reach half final length. Juvenile Vitis vinifera are susceptible infection by powdery mildew...
Nutrient deficiencies are considered a reason for commercial yields of wheat (Triticum aestivum L.) and canola (Brassica napus in the high-rainfall zone (HRZ) southern Australia being well below predicted potential yields. With aim developing soil-test interpretation guidelines suitable HRZ conditions, nutrient-response experiments, 15 with 12 canola, were conducted between 2015 2018. These experiments quantified responses to nitrogen (N), phosphorus (P), potassium (K), sulfur (S), copper...
