Pressure-volume analysis of two grapevine cultivars ('Kékfrankos' and 'Portugieser', Vitis vinifera L.): water deficit, osmotic conditions and their possible relations with drought tolerance
Year: 2015
Type: article
Abstract: Two grapevine cultivars, 'Kékfrankos'and 'Portugieser' rafted onto Teleki-Kober 5BB were investigated during regulated deficit irrigation under greenhouse conditions. Four-year old grapevine plants in 50 L white plastic containers were examined using perlite (20 %), loamy soil (30 %) and peat (50 %) (v/v) mixtureas a substrate. Two treatments were applied: 100 % (nonstressed)and 50 % (moderately stressed) field capacity.'Kékfrankos' has a stronger tolerance against water deficit compared to 'Portugieser' on tissue level. This characteristic is mainly due to the osmotic relations and the elastic tissue properties of this variety. Higher osmotic concentration resulted in delayed turgor loss point,and thus longer cell integrity.
