| Abstract:
In several experiments with a number of varieties it was shown that high budding of the dwarfing rootstocks M.9 and M.26 resulted in weaker trees than normal. Total shoot growth as well as the number of shoots were affected. The lack of branching of the main leader, especially when budded at 30 cm or higher, was considered as a great disadvantage of high-budding. During the first years after planting no differences in cropping were seen between normal- and higher-budded trees. It is expected that in the following years differences in yield will occur due to the current difference in tree volume. A tendency towards smaller fruits seems to exist on trees higher-budded than normal. | |
