Yield modelling of Sauvignon Blanc in Marlborough
Brief:Estimating yield potential of Sauvignon Blanc (and other varieties) is important if suitable infrastructure and marketing is to be available to the industry at harvest. Yield components, berry size, berry number per bunch, bunch number per shoot, shoot number per vine and vines per hectare can be predicted, either by direct measurement (for example, vines per hectare) or by using a basic knowledge of vine physiology. A model has been developed using temperature data at bunch initiation and flowering to predict yield. This will be further refined in the coming seasons, as time allows, to incorporate potential influences of over-wintering carbohydrate reserves on vine development, and expanded to evaluate other varieties and possibly other regions.
