This book was released on 2012 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vine nutrition, particularly N application in wine grapes, is well known to enhance vine vigour and consequently grape and wine quality. Less is known about the interactive effects of N and irrigation on wine quality and Botrytis bunch rot incidence and severity. The Australian Wine Industry in its 5-year research plan (2002-07) identified Botrytis management strategies as a key area requiring a novel approach for minimizing fungicide application, which is critical to marketing of Australian wine both for the domestic and export markets. This study investigated the role of N nutrition and irrigation management for improving vine vigour, quality and yield of fruit through changes in canopy density and improving cuticular thickness of berries for Botrytis cinerea control using Chardonnay in two field-based (vineyard) trials and Chardonnay and Cabernet Sauvignon in glasshouse-based trials. In the first and second year vineyard trials, 0,30 and 300 kg ha-1N were applied to the soil either with or without irrigation. Effects of N nutrition on B. cinerea infection were also investigated using varieties Chardonnay and Cabernet Sauvignon in glasshouse trials under controlled conditions. Nitrogen (N) application in the glasshouse trials ranged from 25-400 kg ha-1. A leaf bioassay was developed to investigate the infection on leaves across varying N levels. Additional studies looked at effects of N treatment on the severity of B. cinerea infection in berries and resveratrol (stilbenes) in grape leaves, berries and wine in vineyards. In both vineyards, the N applied did not result in significant changes in canopy density, shoot length, yield, or wine quality parameters (OBrix, pH, acidity, total phenols, and N in berries). Also, no significant differences were seen in different levels of N treatment with respect to B. cinerea severity, and stilbene levels in vines over a 2-year period. In glasshouse trials, low N levels (25 kg ha-1) resulted in reduced shoot vigour, low yields and high susceptibility to infection. In contrast, N applications (200 and 400 kg ha-1) maximized vigour (wet cane weight) and imparted resistance in Chardonnay against B. cinerea infection. In Cabernet Sauvignon, the highest level of N application (400 kg ha-1) proved most beneficial in improving vigour and resistance against B. cinerea infection. Preliminary (qualitative) studies on the wax morphology of the berry surface using scanning electron microscopy (SEM) revealed delayed secondary wax plate formation during the veraison period in some replicates of the high N and no irrigation treatment. Further intensive studies would be needed to explore this observation. Light microscopy studies performed to assess the cuticular thickness of the berry at different N treatments did not show any appreciable changes at different stages of berry growth. Field experimental results have implications for farmers and suggest that in regions where vines and soil are not deficient in N, grape growers could avoid excessive soil application of N fertilisers and irrigation to enhance vine vigour for minimizing B. cinerea infection.

Book Synopsis Characterizing Grapevine Canopy Architecture by : Alejandra Navarrete
Download or read book Characterizing Grapevine Canopy Architecture written by Alejandra Navarrete and published by . This book was released on 2015 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertically shoot positioned (VSP) training systems are common in Oregon's Willamette Valley, where deep fertile soils and high regional precipitation task growers with curbing vegetative vigor within this system. Management strategies, such as canopy hedging and cluster-zone leaf removal, are used to improve microclimate within the canopy and around the fruit. These cultural practices employed in commercial vineyards make it difficult to quantify canopy architecture and vine growth using currently established methods. Given the importance of vine leaf surface area to productivity of the vine, a study was conducted to determine how to best quantify leaf area in the highly managed VSP canopies. A regression model was developed from various linear leaf measures compared to leaf area measures on primary and lateral leaves of Pinot noir vines in the north Willamette Valley of Oregon. Maximum leaf length, maximum leaf width, mid-vein length and the distance between the central and interior lateral lobe tips were positively associated with total leaf area. Leaf width at the petiole junction was not a suitable measure. A second study was conducted to evaluate methods for quantifying vine leaf area and leaf distribution in moderate and high vigor VSP canopies, where dense foliage and interlacing shoots and tendrils can make vine measurements difficult. Traditional point quadrat analysis, digital photography, and a template leaf area method were compared to leaf areas determined by destructive sampling. Results show that point quadrat analysis severely overestimated the number of shaded canopy leaves in dense VSP systems. Results from the digital photography pixel recognition program correlated green pixels with leaf exposure but was not in good agreement with exterior canopy leaf area. The template leaf area method results confirm that it can accurately estimate total vine leaf area. The third study was developed to integrate these canopy quantification techniques with understanding how the leaf area: yield relationship affects fruit composition at harvest in cool climate Pinot noir grapes. A range of leaf area to yield ratios was created by cluster thinning vines to two crop levels. The study was replicated across four commercial vineyards with varying levels of moderate and high vigor. Results indicate that crop thinning had no impact on canopy leaf area, and there was limited impact of yield on fruit composition over two seasons. The studies included herein aimed to develop and evaluate methods for estimating leaf area within VSP-trained canopies in the Willamette Valley. Results of this work will provide improved methods by which viticulture researchers and whole-plant physiologists can employ to determine leaf area as a measure of vine productivity, and better understanding of source-sink relationships in managed canopies.

Book Synopsis Viticulture and Winemaking under Climate Change by : Helder Fraga
Download or read book Viticulture and Winemaking under Climate Change written by Helder Fraga and published by MDPI. This book was released on 2019-12-19 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of viticulture and the winemaking socio-economic sector is acknowledged worldwide. The most renowned winemaking regions show very specific environmental characteristics, where climate usually plays a central role. Considering the strong influence of weather and climatic factors on grapevine yields and berry quality attributes, climate change may indeed significantly impact this crop. Recent trends already point to a pronounced increase in growing season mean temperatures, as well as changes in precipitation regimes, which have been influencing wine typicity across some of the most renowned winemaking regions worldwide. Moreover, several climate scenarios give evidence of enhanced stress conditions for grapevine growth until the end of the century. Although grapevines have high resilience, the clear evidence for significant climate change in the upcoming decades urges adaptation and mitigation measures to be taken by sector stakeholders. To provide hints on the abovementioned issues, we have edited a Special Issue entitled “Viticulture and Winemaking under Climate Change”. Contributions from different fields were considered, including crop and climate modeling, and potential adaptation measures against these threats. The current Special Issue allows for the expansion of scientific knowledge in these particular fields of research, as well as providing a path for future research.
