From year to year the percentage of rooted grafts originating from an SO 4 nursery was less than that originating from a 5C nursery. The two rootstocks showed differences in callusing capacity and also in K content of the leaves (1.1-1.4 and 0.6-1.0% for SO 4 and 5C, respectively). To determine whether nutrient content affected callusing capacity, cuttings of both rootstocks were grown in pots and supplied with nutrient solutions of different compositions.
