Variación temporal de indicadores microbiológicos y químicos de suelo árido regadío incubado con abonos orgánicos
(2018-08)Las características microbiológicas y químicas del suelo cambian por la aplicación de abonos orgánicos y pueden resultar indicadores sensibles al impacto producido. El objetivo de este estudio fue evaluar los cambios a ... -
Varietal richness of grapevine (Vitis vinifera L.) from the Majes Valley, Peru: Identification, morphological characterization, ampelographic and genetic analysis
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Trujillo (Perú), 2022-08-18)The “Majes Valley” in the province of Castilla – Arequipa Region, with a tradition in the production of wine and pisco, from grapevines introduced in the mid-sixteenth century, which are still preserved by some producers, ... -
Vine age affects vine performance, grape and wine chemical and sensory composition of cv. Zinfandel from California
(American Society for Enology and Viticulture (ASEV), 2022-10-18)The wine industry regards old vines as nonpareil because of the vine’s decreased capacity to set and mature fruit, which results in superior wine quality. Here we report the viticultural, chemical, and sensory effects of ... -
Vineyard zoning of cv Bonarda argentine (Vitis vinífera L.), from Sentinel satellite images and three vegetation indexes = Zonificación de un viñedo de cv Bonarda argentina (Vitis vinífera L.) a partir de imágenes del satélite Sentinel y tres índices de vegetación
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2019-12)This study describes the results and conclusions obtained from vineyard zoning in Mendoza by using three vegetation indexes (NDVI, EVI and SAVI). Such indexes were calculated from spectral signals received by the Sentinel- ... -

Volatile Profile Characterization of Extra Virgin Olive Oils from Argentina by HS-SPME/GC-MS and Multivariate Pattern Recognition Tools
(2014-11)The distinctive aroma of virgin olive oil is attributed to a large number of chemical compounds of different classes such as aldehydes, alcohols, esters, hydrocarbons, ketones, furans, and other volatile compounds that are ... -
Water: tools and functions to estimate actual evapotranspiración using Land Surface Energy Balance Models in R
(2016-12)The crop water requirement is a key factor in the agricultural process. It is usually estimated throughout actual evapotranspiration (ETa). This parameter is the key to develop irrigation strategies, to improve water use ... -
Whole cluster and dried stem additions effects on chemical and sensory properties of Pinot Noir wines over two vintages
(American Society for Enology and Viticulture, 2020-08)The effect of whole cluster at 50% (50% WC) and 100% additions (100% WC), as well as that of Dried stems (DS) on Pinot noir wines from the Edna Valley AVA of California (USA) were investigated over two consecutive vintages ... -
Whole genome resequencing and custom genotyping unveil clonal lineages in ‘Malbec’ grapevines (Vitis vinifera L.)
(Springer Nature, 2021-04-08)Grapevine cultivars are clonally propagated to preserve their varietal attributes. However, genetic variations accumulate due to the occurrence of somatic mutations. This process is anthropically influenced through plant ... -
Whole plant open chamber to measure gas exchange on herbaceous plant
(2016)Much of our understanding about CO2 and H2O gas exchange in plants has been gained from studies at leaf level. Extrapolation of results to whole plant is difficult and not always accurate. In order to overcome this limitation, ... -
