Effects of early leaf removal on volatile compounds concentrations in Cabernet Sauvignon wines from the Ilok vineyards
The aim of this two year study was to evaluate effects of basal leaf removal before blooming on volatile composition of Cabernet Sauvignon wines in the Ilok vineyards (eastern Croatia). During two consecutive vintages (2013, 2014), two different treatments of basal leaf removal were applied: removal of 3 and 6 leaves, and control without leaf removal. Volatile compounds of resulting wines were identified and quantified by gas chromatography coupled with mass spectrometry. Organic acids and higher alcohols remained unaffected by treatments of early defoliation wine, except acetic acid and 2-methyl-6-hepten-1-ol. Early leaf removal was affected on six esters concentration only in the 2014 with different outcome. For compounds unaffected by defoliation, vintage was statistically significant source of variability, as the results of multivariate analysis have confirmed. Defoliation treatments in Cabernet Sauvignon wines from eastern continental part of Croatia should be adjusted to the weather condition in growing season.
期刊介绍：
POLJOPRIVREDA“ (AGRICULTURE), a scientific-professional journal has been issued since 1995 by the Faculty of Agriculture in Osijek and Agricultural Institute Osijek . The journal is a successor of the former one „Science and practice in agriculture and food technology“ printed from 1982 to 1994. The journal „Poljoprivreda“ is known for publishing scientific and professional articles from all fields of agricultural science and profession. The papers are reviewed. Articles are categorized by two independent referees and approved by Editorial board and Editor – in – chief. Summaries of master"s and doctor"s theses are also published as well as other contributions by the special decisions of the Editorial board.
