Orientamento dei filari e sfogliatura: effetti sulla qualità dell’uva nella cv Cabernet Sauvignon

Risultato della ricerca: Articlepeer review


The aim of this study was to evaluate the influence of partial defoliation on canopy sides of two vineyards, which had two different row orientations and were exposed to solar radiation for different num- bers of hours during the day. The experiment was carried out in Sicily in two irrigated vineyards of cv Cabernet Sauvignon (clone 377) grafted onto 1103 P rootstock, with a different row orientation: North- East/South-West (vineyard A) and North-West/South- East (vineyard B). The canopy sides that received less hours of solar radiation had higher anthocyanins contents. The defoliation treatment, instead, did not improve the grape quality, but, sometimes, it accele- rated anthocyanin synthesis.
