Abstract
Argentinean
Vitis vinifera cultivars although originated from Europe, have clear ampelographic and genotypic differences as compared with the European cultivars currently used in wine making.
In vitro evaluation of salt tolerance has been used in many species. Our hypothesis was that Argentinean cultivars are more tolerant to salinity than European ones. Three European cultivars, Malbec, Cabernet Sauvignon and Chardonnay and four Argentinean cultivars, Cereza, Criolla Chica, Pedro Gimenez and Torrontes Riojano were tested by
in vitro culture. Treatments included: 1) Control, 2) 60 mEq/L of a mixture of three parts of NaCl and one part of CaCl
2 and 3) 90 mEq/L of the salt mixture. Results from two experiments (I and II) are reported. No differences were found in plant survival, expressed as % of the respective control, among cultivars. Leaf area, leaf, stem and total dry matter (DM) in Experiment I and leaf area, leaf number and leaf, stem, root and total DM in Experiment II, were higher in Argentinean cultivars than in European ones. We conclude that Argentinean cultivars show better performance in growing under salinity, especially in the highest salt concentration. Differences among cultivars, inside each group, were found for most of the measured variables.
