| Abstract:
During the spring of 1992, two different experimental fields were planted in the North and South of Poland with plum rootstock trials. Two seedling rootstocks, P. divaricata and Wangenheim Prune, as well as the clonal rootstock ‘Pixy’ were compared with the scion cultivars ‘Oullins Golden Gage’, ‘Cacanska Najbolja’, ‘Stanley’, ‘Empress’ and ‘Valor’. The trees of all the studied plum cultivars on P. divaricata seedlings had larger TCSA than those tested on other rootstocks. No significant differences between Wangenheim Prune seedlings and the clonal rootstock ‘Pixy’ were found in the vigour of nine-year-old trees. In both localities yield efficiency was very high for trees grafted on Wangenheim Prune seedlings. In the case of the other two rootstocks the productivity index varied depending on the cultivar and yield per tree. | |
