Vineyard Spatial Structures of Key Soil, Vine and Fruit Metrics Are Hierarchically Associated
Understanding vineyard spatial structure can help optimise grape production and ultimately wine quality by targeting the application of inputs through precision viticulture methods. We explored the spatially dependent variability of various soil, vine and fruit parameters, including yield and grape composition, in a South Australian Shiraz vineyard located in the Barossa Valley during the 2022/23 season. Our aim was to investigate the interdependencies between spatial structures within a vineyard block as related to soil and vine metrics, including predawn leaf water potential, midday stem water potential and leaf gas exchange under different soil moisture conditions. Maps of each parameter were produced using 114 spatially separated data points per variogram. Yield components were measured at harvest, and fruit composition was assessed at harvest across the vineyard at the same points. Soil parameters were found to have stronger spatial structure than vine parameters (e.g., leaf gas exchange, stem water potential) and were therefore deemed to be better predictors of overall vineyard variability. The pattern of spatial variability of a given soil or vine parameter was influenced by the spatial pattern of the underlying parameters that influence it.
期刊介绍:
The Australian Journal of Grape and Wine Research provides a forum for the exchange of information about new and significant research in viticulture, oenology and related fields, and aims to promote these disciplines throughout the world. The Journal publishes results from original research in all areas of viticulture and oenology. This includes issues relating to wine, table and drying grape production; grapevine and rootstock biology, genetics, diseases and improvement; viticultural practices; juice and wine production technologies; vine and wine microbiology; quality effects of processing, packaging and inputs; wine chemistry; sensory science and consumer preferences; and environmental impacts of grape and wine production. Research related to other fermented or distilled beverages may also be considered. In addition to full-length research papers and review articles, short research or technical papers presenting new and highly topical information derived from a complete study (i.e. not preliminary data) may also be published. Special features and supplementary issues comprising the proceedings of workshops and conferences will appear periodically.
