Climatic potential for viticulture in Central Chile

Abstract

Artículo de publicación ISIBackground and Aims: Central Chile represents a large area of viticultural potential for high-quality wine production. Although climate has been commonly accepted as one of the main drivers of Chilean viticultural success, its main features have not been described from a viticultural perspective. Our work focused on analysing the spatial climatic structure in this area with respect to the potential for grapevine production.CYTED of Ibero-Americ

Phenology and Ripening of Vitis vinifera L. and Vitis labrusca L. Varieties in the Maritime Climate of Samsun in Turkey’s Black Sea Region

“…Lorenzo et al (2012) also reported that the Rías Baixas coastal region, one of the most productive viticultural regions in Spain, lies below an altitude of 300 m and has an Atlantic climate, with a mean annual temperature of about 15°C and an annual rainfall of about 1 600 mm. Montes et al (2012) reported that the Casablanca Valley in Chile, near the eastern edge of the Maipo, Cachapoal and Maule Valleys -the highest zones near the Andes, is classified as temperate according to the HI (HI 1988). Although the heliothermal potential of such locations limits the cultivation of red wine varieties such as Cabernet Sauvignon and Carménère, which have relatively high thermal requirements, they can be suitable for early-ripening varieties such as Pinot Noir and Riesling.…”

Effect of water application on wine quality and yield in 'Carménère' under the presence of a shallow water table in Central Chile

“…The study lasted three seasons (2004-2005, 2005-2006, and 2006-2007) and was conducted in a drip-irrigated vineyard (Vitis vinifera L.) with own-rooted 'Carménère' vines established in 1997; vine spacing between rows was 2.5 m and vine spacing within the row 1.5 m. The zone has a sub-humid Mediterranean climate with a mean maximum temperature of 32 ºC in January, an annual mean of 14 ºC, and annual mean rainfall of 564 mm with a standard deviation of 236 mm, with 92% annual amounts during May to September for the period 1960 to 2006 (Arumí et al, 2013). There is high heat accumulation (heliothermal index, HI = 2441), which is a suitable condition for 'Carménère' (Montes et al, 2012). The soil is Typic Xerochrepts, alluvial origin, surface slope about 0.4% to the south, with a clay loam texture at the surface that varies to sandy loam at 1.0 m depth, and coarse sand, gravel and stone at depths greater than 1 m; soil bulk density 1.66 Mg m Figure 1 shows a field layout of the general condition of the Peumo area and the site of experiment.…”

Impact of climate change on some grapevine varieties grown in Peru for Pisco production

“…Four bioclimatic indices commonly used in grapevine-related studies (Tonietto and Carbonneau, 2004 ;Hall and Jones, 2010 ;Montes et al, 2012) are determined : the average Growing Season Temperature (GST), the Growing DegreeDays Index (GDDI), the Huglin's Heliothermal Index (HI) and the Cool Night Index (CNI). They are calculated over the entire growing season, from October to April, as described below, except the HI which is calculated from October to March.…”
