Abstract
AbstractResults from an 8-year-old Jonathan rootstock trial at Havelock North Research Orchard are presented. The following vigorous selections, Merton 779, 789, 793 ; Mailing XXV, 411, and Malling-Merton 109 were compared with Mailing XVI, II, and Northern Spy.It was found that Merton 793 was the most promising vigorous rootstock and Northern Spy was still the best selection of moderate vigour.Heavy cropping was found to be associated with a spreading habit of growth.It is suggested that tree volume may be a more reliable indication of tree size than trunk girth.The adverse influence of an adjoining poplar hedge was clearly demonstrated.
