“…By the end of the seventh growing season, at the end of August, 25 leaves from the middle of current year shoots of each tree were sampled and dried at 708C. For determination of K, Mg, Ca, and P in the leaves, the plant material was digested in a 1:2:5 mixture of sulfuric, perchloric, and nitric acids, respectively (Oland & Opland, 1956). The determination of cations was achieved by atomic absorption spectrophotometry.…”

The performances of the plum rootstocks Marianna GF 8-1, Pixy, and Wangenheim, compared with St. Julien A as a standard, for the cultivars 'Avalon', 'Edda', 'Excalibur', 'Jubileum', 'Reeves', and 'Victoria' were assessed in a field trial in western Norway at 608 North. Trees were planted in spring 1999; the plant material was one-year-old whips, spaced 2.0 )4.5 m and formed with a central leader as free spindles. Tree vigour, yield, fruit size, fruit quality, and yield efficiency were evaluated for the seven subsequent years. Tree size was significantly affected by the rootstocks after seven years' growth. Wangenheim produced the smallest and St. Julien A and Pixy the largest trees as measured by trunk cross-sectional area, on average for the different cultivars. However, Pixy produced significant larger yields per tree for the cultivar 'Reeves' than did St. Julien A. 'Edda' gave the smallest yield and 'Avalon the largest. Trees on Pixy were the most yield efficient for all cultivars with the exception of 'Victoria'. The fruit sizes became little affected by the different rootstocks. 'Edda' and 'Victoria' produced the smallest fruits and 'Excalibur' and 'Reeves' the largest. Fruit quality characterized by the content of soluble solids was on average 16.1% and did not differ between trees on the various rootstocks. The cultivar 'Avalon' had the highest contents of soluble solids and 'Reeves' the lowest. The nutrient levels in the leaves were within the optimum range by the end of the seventh season. Trees on Marianna GF 8-1 had the highest nitrogen and magnesium leaf uptake. In conclusion, St. Julien A and Pixy were the most reliable semi-vigorous rootstocks which induced high yield efficiency and with favourable influences on fruit quality to the six European plum cultivars. Pixy is a good alternative to St. Julien A, with a lower vigour in trees, more precocity, and higher yield efficiency.

“…Exchangeable cations and soil phosphorus were extracted according to the method described by EgnCr et al (1960). For determination of K, Mg, Ca and P in the leaves, the plant material was digested in a 1:2 mixture of perchloric and nitric acids (Oland & Opland, 1956). The determination of cations was achieved by atomic absorption spectrophotometry.…”
