Abstract:
Three different American vine rootstocks (99 R, 420 A, 1616 C) were used for the study. Before exposing to salt stress, cuttings were immersed in to salicylic acid solutions at 4 different doses (0, 3, 6 and 9 mM). Saline water treatments lasted after 8 weeks. About 2 months later, the parameters of root and shoot chlorophyll content, leaf K (%), Ca (%), Mg (%), Na (ppm) content were investigated to assess the efficiency salicylic acid treatments. Less damage levels were observed in all three rootstocks under saline conditions with increasing salicylic acid doses and increasing root and shoot tolerance rates were observed with treatments. Treatments under saline conditions had positive effects on root and shoot development and leaf nutrient (K, Ca and Mg) contents.
