Study for the relationship between whole plant moisture content and the shoot hardwood cuttings and NaCl concentration of four antiphylloxeric rootstocks of grapevine was conducted during 2014 -2015 at the Experimental Base of the Agricultural University of Tirana. Rooted rootstock’s cuttings were irrigated using normal tap water up to July 20, and, after that, for 45 days, were irrigated using sodium chloride solucion in six different concentrations [control (normal tap water), 2000, 4000, 6000, 8000, and 10000 ppm]. Obtained results showed that with the increase of NaCl concentration, the whole plant moisture content and the hardwood cuttings, was decreased for all rootstocks under study. For the same NaCl concentration, the moisture content of the entire plants and shoot hardwood cuttings were different for different rootstocks. Ranking of rootstocks, according to the plant moisture content, was 1103P (83.2-83.6%), followed by 140Ru (79.5-79.8%), SO4 (79.3-79.5%) and Kober 5BB (79.03-79.2%). The moisture content of shoot hardwood cuttings was lower than moisture content of the whole plant. Ranking of the rootstocks, according to the moisture content of hardwood cuttings, was 1103P (58.2-58.4%), 140Ru (59.8-59.9%), Kober 5BB (55.6-55.9%) and SO4 (54.9-55%). Ampelographic assessment of the resistance of the rootstocks to chlorides (salt) was carried out using OIV Code 402. Rootstock SO4 was more sensitive and less resistant to sodium chloride concentration compare to 1103 P, 140Ru and Kober 5BB. There were significant differences (≤ 0.01) in plant moisture content between NaCl treatments and tested rootstocks.
