• No commercial equipment aimed to measure grape bunch transpiration is available. A new open chamber system that monitors berries/bunch presented. The prototype based on the use of relative humidity sensors. Detaching from plant did not alter gas exchange for several hours. An increased berry resulted in a speeded maturation. Grape considered an important process during maturation, but scienti...

Abstract The objective of this work was to evaluate the agronomic responses 'BRS Vitória' grapevines under bio-fertigation with and without conventional soil fertilizer. A completely randomized design used, three treatments 18 replicates. were: CFI, fertilizer irrigation; BF+CF, fertilizer; BF, only bio-fertigation. following variables were evaluated: graft rootstock diameters; plant growth; nu...

Viticulture is widely practiced in dry regions, where the grapevine is greatly exposed to water stress. Optimizing plant water use efficiency (WUE) without affecting crop yield, grape and wine quality is crucial to limiting use of water for irrigation and to significantly improving viticulture sustainability. This study examines the use in vineyards of particle film technology (engineered kaoli...

Abstract Quantitative evaluation of the horticultural crops has high importance to identify cultivars, describe effect growing location and cultivation technology or define consumer's preference regarding size shape. Fruit traits grapevine ( Vitis vinifera L.) are mainly described by bunch berry morphology notably size, weight Ampelographers particularly evaluate based on seed number as it infl...

This paper presents the most important morphological and production-technological characteristics of newly created grapevine varieties Vozd Vladun, intended for production red wines. The were compared with standard variety Cabernet Sauvignon during three-year period testing (2015-2017) in relation studied properties. obtained from crossing combination Zacinak x Prokupac, Vladun Merlot Zupski Bo...
