| Abstract | ||||
| The present investigation was carried out during 2000 and 2001 growing seasons in order to study the effect of sodium chloride and sodium carbonate treatments on growth of four grapevine cultivars (commonly used as rootstocks) namely, Harmony, 1103 Paulsen, Dogridge and Thompson seedless. The main results can be summarized in the following points: A. Effect of salinity treatments Plant height, growth rate, number of leaves, leaf area, pruning wood weight and plant fresh and dry weight, in both seasons. Number and diameter of shoots, in the second season only, significantly decreased with the different sodium chloride and sodium carbonate treatments. On the other hand, shoot/ root ratio significantly increased with salinity treatments. Stem diameter was not significantly affected with salinity treatments, in both seasons, however. B. Effect of rootstocks In both seasons, Thompson seedless had significantly higher leaf area and dry weight, shoot diameter, root fresh and dry weight and lower leaves number. In the meantime, Dogridge had significantly higher average plant height in both seasons and shoot / root ratio, at the end of the experiment. Harmony had significantly lower shoots and roots fresh and dry weight, while 1103 Paulsen had significantly higher leaves number and lower leaf area, in both seasons. | ||||
