Abstract:

An experiment was conducted at Grape Research Station, Rajendranagar, Hyderabad to study the relative salt tolerance of grape rootstocks at different levels of sodium chloride. The treatments consisted of five rootstocks viz., Dogridge, Salt Creek, RS-19, SO4 and 1613-C and five levels of sodium chloride 4, 8, 16 and 32 meq of Cl/lt in irrigation water  including  control (normal irrigation water ).The experiment was laid out in a FCRBD with three replications. The relative salt tolerance was judged based on growth parameters, dry weight of root to shoot ratio, symptoms of toxicity, chloride content K/Na ratio in leaf and days taken for appearance of toxicity symptoms. The dry weight of root to shoot ratio was significantly higher in Dogridge (0.6) and RS-19 when compared to others. The K/Na ratio in 1613-C (14.1) SO4 (13.4) and RS-19 (10.3) was significantly higher than Dogridge (8.8) and Salt Creek (7.4). Dogridge was the best chloride excluder based on lowest concentrations of accumulated Cl- in laminae (0.8%.). The scorching symptoms due to salt toxicity were observed earlier in RS 19 followed by Salt Creek, Dogridge, 1613 C and later in SO4. High innate vigour (high dry weight of root to shoot ratio and growth parameters) of Dogridge combined with high chloride exclusion ability represents the best combination for salt tolerance which however, could not be supported by low K/Na ratio. In case of 1613 C and SO4, the high K/Na ratio and late appearance of salt toxicity symptoms  supported salt tolerance but less vigour and  chloride exclusion were not in support relative to Dogridge. In all the rootstocks there was progressive decline in the growth parameters, K/Na ratio, root to shoot ratio and increase in chloride content with the increase in concentration of NaCl over control. Such information further supported by field studies could assist in assessment of rootstocks for areas of high salinity.
