| Abstract:
At the Wilanów Experimental Station on an alluvial loamy soil twenty two rootstocks of different origin were compared: P 2, P 22, P 14, P 16, Nr 47, P 59 and P 60 (all from the Polish breeding programme); B 9, B 146 (57-146) and B 396 (62-396) (Russian selection); PB-4 (Belarussian selection); M.7, M.26, M.27 and eight M.9 sub-clones (EMLA, T337, T339, 75l, 984, RN29, Pajam 1 and Pajam 2). Leaves of rootstocks were sampled from stoolbeds and a nursery and leaves of 'Elise' scion on different rootstocks in the nursery and in the orchard. P 16 and P 14 promoted a higher leaf N concentration. PB-4 and 'Elise' grafted on it contained less N and P. M.7, P 60 and P 14 usually favoured higher P concentrations. In respect to K, Mg and Ca results were rather erratic; those observed in the orchard did not reflect differences noted in stoolbeds or in the nursery. A high variation of leaf nutrient concentrations due to season was also observed. It was difficult to relate a significant differences between rootstocks to their vigour, origin or depth of rooting. | |
