Influence of wind direction on the surface roughness of vineyards
(Springer Verlag, 2018-11-27)
Remote sensing-based models are the most viable means of collecting the high-resolution spatially distributed estimates of evaporative water loss needed to manage irrigation and ensure the effective use ...
Determining a robust indirect measurement of leaf area index in California vineyards for validating remote sensing-based retrievals
(Springer Verlag, 2018-12-05)
Accurate ground-based measurements of leaf area index (LAI) are needed for validation of remote sensing-based retrievals used in models estimating plant water use, stress, carbon assimilation and other ...
Utility of the two-source energy balance (TSEB) model in vine and interrow flux partitioning over the growing season
(Springer Verlag, 2018-09-14)
For monitoring water use in vineyards, it becomes important to evaluate the evapotranspiration (ET) contributions from the two distinct management zones: the vines and the interrow. Often the interrow ...
Water stress during the post-harvest period affects new root formation but not starch concentration and content in Chardonnay grapevine (Vitis vinifera L.) perennial organs
(Elsevier, 2019-02-15)
Water stress responses during the post-harvest period were evaluated in a Chardonnay container-grown grapevines grafted onto 1103 Paulsen rootstock. The irrigation treatments were: a control treatment ...
Long proleptic and sylleptic shoots in peach (Prunus persica L. Batsch) trees have similar, predetermined, maximum numbers of nodes and bud fate patterns
(Oxford University Press, 2019-01-03)
Background and Aims
In peach (Prunus persica) trees, three types of shoots can be distinguished depending on the time of their appearance: sylleptic, proleptic and epicormic. On proleptic shoots, an ...
Genotypic variability in radial resistance to water flow in olive roots and its response to temperature variations
(Oxford University Press (OUP), 2020-02-06)
As radial root resistance (Rp) represents one of the key components of the soil–plant–atmosphere continuum resistance catena modulating water transport, understanding its control is essential for ...
Performance of a Chill Overlap Model for Predicting Budbreak in Chardonnay Grapevines over a Broad Range of Growing Conditions
(American Society for Enology and Viticulture (ASEV), 2018-09-26)
Predicting phenological stages through modeling has significant implications for planning viticultural practices and for predicting the impact of climate change on phenology. The Chill Overlap Model is ...
Evaluation of TSEB turbulent fluxes using different methods for the retrieval of soil and canopy component temperatures from UAV thermal and multispectral imagery
(Springer, 2018-09-14)
The thermal-based Two-Source Energy Balance (TSEB) model partitions the evapotranspiration (ET) and energy fluxes from vegetation and soil components providing the capability for estimating soil evaporation ...
Assessment of different methods for shadow detection in high-resolution optical imagery and evaluation of shadow impact on calculation of NDVI, and evapotranspiration
(Springer Verlag, 2018-12-03)
Significant efforts have been made recently in the application of high-resolution remote sensing imagery (i.e., sub-meter) captured by unmanned aerial vehicles (UAVs) for precision agricultural applications ...
Using forced regrowth to manipulate Chardonnay grapevine (Vitis vinifera L.) development to evaluate phenological stage responses to temperature
(Elsevier, 2019-12-06)
Time and environmental conditions, such as temperature and photoperiod, are the main drivers governing grapevine development over the growing season. The most obvious growth periods in grapevines are ...
