Zoning influence in chromatic parameters in Monastrell grape

Abstract

Zoning analysis determine homogeneous areas principally from the point of view of the medium, giving as a result a map which cartographic units synthesize the relations between the edaphic factors; morphological factors of the soil and climatic factors. The combination of these types of parameters allows to obtain maps of suitability of the optimum areas for the crop of the vineyard. At present it has been delimited and characterized eight grape areas belonging to the D.O. Jumilla. The chosen plots has been: Varahonda, Cañada del Judío, Cañada de Albatana, El Carche, Rubializas, Agüeros, Cortijo del Agrio and Casa Vistalegre. 
The determined parameters are: Phenological parameters: Dates of sprouting, flowering, veraison, and harvest. Chemical parameters during maturation: total phenolic compounds, anthocyanins to pH 1 (extractable anthoc.) and anthocyanins to pH 3 (Total anthoc.), seed ripeness (MP) and index of cellular ripeness (IMC). 
As for the determination of chromatic parameters and of extractability, in the plot of Cortijo del agrio the biggest quantity of anthocyanins has been obtained on having finished the period of ripening, on the other hand the plot of Cañada del Judio is the one that has obtained the highest values of extractable polyphenols. In our study, for the IMC lower value has been obtained for the plot located in Cañada del Judio and the highest value for the plot of Cortijo del agrio. As for seed ripeness Rubializas and Cortijo del agrio are the plots that obtained the lowest values.

Effects of mesoclimate on the yield, quality and phenolic maturity of Grenache

The potential climate change, due to global change, will increase temperature general and could increase at local level. These changes are not going to be the same in different parts of the world, being especially important in the Mediterranean Basin.

Organic volatile compounds as suitable markers of grapevine response to defense elicitors in the vineyard

In greenhouse, emission of volatile organic compounds (VOC) by grapevine leaves has already been reported in response to the defence elicitor sulfated laminarin (PS3) [1]. In order to check that this response was not specific to PS3, experiments were conducted on Vitis cv Marselan plantlets with several other elicitors of different chemical structures: i.e. Bastid® (COS-OGA),

Environmental and yearly influences on four Sicilian grape clones under climate change challenges

By the end of this century, up to 90% of traditional viticulture regions in the Mediterranean, including Sicily, are projected to face extinction due to escalating climate challenges such as severe droughts, heatwaves, and unseasonal rains.

PHENOLICS DYNAMICS OF BERRIES FROM VITIS VINIFERA CV SYRAH GRAFTED ON TWO CONTRASTING ROOTSTOCKS UNDER COMBINED SALINITY AND WATER STRESSORS AND ITS EFFECT ON WINE QUALITY

Wine regions are getting warmer as average temperatures continue raising affecting grape growth, berry composition and wine production. Berry quality was evaluated in plants of Vitis vinifera cv Syrah grafted on two rootstocks, Paulsen (PL1103) and SO4, and grown under two salinity concentrations (LS:0.7dS/m and HS:2.5dSm-1) in combination with two irrigation regimes (HW:133% and CW:100%), being the seasonal water application 483mm (control, 100%). Spectrophotometer measurements from berry skin during veraison and harvest stages and from “young” wine samples, were indicative of the stressors effect and the mediation of the rootstocks. At veraison (i) total phenolics content were high under LSHW (0.7dSm-1 and high water conditions) for SO4 and PL1103.

Estimation of stomatal conductance and chlorophyll fluorescence in Croatian grapevine germplasm under water deficit    

Water deficit profoundly impacts the quality of grapes and results in considerable reductions in crop yield. First symptoms manifest with reduced stomatal conductance and transpiration, accompanied by the wilting of apical leaves and tendrils. So far, there is no available data on the water stress response in Croatian grapevine germplasm. Therefore, objective of this study was to determine influence of genotype and treatment on stomatal conductance (gsw), transpiration (E), electron transport rate (ETR), and quantum efficiency in light (PhiPS2).
