Determination of salt tolerance of some American grape rootstocks

To determine salt tolerance of four American grape rootstocks, 1103 P, 41 B, 140 Ru and 5 BB, characteristics measured were fresh and dry weight of root, fresh and dry weight of shoot, fresh and dry weight of plant, plant moisture, cutting moisture, shoot length, node number and leaf number. Salt tolerance of the rootstocks was determined by both tolerance rate and index values on the basis of shoot and root dry weights, and interpreted with plant viability. Results obtained indicated that 41 B was the most resistant rootstock, followed by 140 Ru and 1103 P, and the least resistant was 5 BB.
