Artificial Neural Network to Predict Vine Water Status Spatial Variability Using Multispectral Information Obtained from an Unmanned Aerial Vehicle (UAV)
Water stress, which affects yield and wine quality, is often evaluated using the midday stem water potential (Ψstem). However, this measurement is acquired on a per plant basis and does not account for the assessment of vine water status spatial variability. The use of multispectral cameras mounted on unmanned aerial vehicle (UAV) is capable to capture the variability of vine water stress in a ...
متن کاملHow to Sample to Calibrate a Spatial Model: Application for Modelling Vine Water Status
Several studies have shown that vineyards are spatially variable at within field scale. Characterizing this variability could be used to improve grape and wine production, by adapting management practices and harvesting to the vineyard variability. The goal of this work is to calibrate a spatial model by coupling high quality, high cost punctual vine measurements with low cost medium-high densi...
متن کاملManagement practices impact vine carbohydrate status to a greater extent than vine productivity
Light pruning and deficit irrigation regimes are practices which are widely used in high yielding commercial vineyards in the warm climate regions of Australia. Little information is available on their impacts on carbohydrate dynamics in vegetative organs within and between seasons, and on the resulting plant capacity to maintain productivity and ripen fruits. This study was conducted to addres...
متن کاملAssessing Soil Health for Tree Fruit and Vine Crops
What is soil health? The objective of this presentation is to present information on the types of measurements of soil biological properties that might be useful as bio-indicators of soil health. First, however, it is necessary to discuss what soil health means. Scientists, farmers and land managers have long known that there is more to the productive capacity of soil than what can be predicted...
متن کاملVine pollen allergy in areas with a high density of vineyards.
BACKGROUND In Castilla-La Mancha, Spain, the area with the highest density of vineyards in the world, 2 cases of Vitis vinifera pollen allergy have been previously reported. OBJECTIVE To determine the clinical relevance and biochemical characteristics of vine pollen in the Spanish province of Ciudad Real. METHODS We designed a prospective study of patients treated in the allergy units from ...
