INFLUENCE OF INTERSTOCK ON APPLE TREES |
| Author: | K. Karp |
| Abstract:
In 1979 were planted a trial of interstock apple trees in the garden of Estonian Agricultural University. There have been tested cultivars 'Talvenauding' and 'Tellissaare'. The Tested trees were on Antonowka seedling with 10 or 15 cm-long B9 and with 15 or 20 cm-long 57–490 interstocks. The trees with interstock were compared with the trees grafted directly onto 57–490 clonal rootstock. The roots of dwarfing interstock trees have the same circle of stretsch and vigour of growth as the rootsystem of medium growing interstock or clonal rootstock trees. Production on 57–490 was not greater than that on Ant./57–490. but production of trees 'Tellissaare' on Ant/B9 (15 cm) was greater than that on 57–490. | |
