The availability of Pyrus rootstocks that reduce tree size, enhance precocity and are also easy to propagate is limited. In general, European pears are considered a difficult-to-root species, and this trait is one of the obstacles to developing succe

Use of well-feathered trees when establishing an orchard promotes early cropping; however, many pear cultivars do not readily form sylleptic branches in commercial nurseries. Observations of young trees of the interspecific pear ‘PremP109’ sugges

Young trees of the recently commercialised apple ‘Scilate’ (EnvyTM) appear precocious, have excessive fruit set, and produce naturally large fruit. Without precise control of cropping, these characteristics could limit vegetative growth of young

Contemporary dwarfing and semi-dwarfing root stocks cultivated extensively worldwide lack durable resistance to economically damaging pests and diseases. In recognition of these limitations, a series of hybrid families was created in 1986-87 by cross

SummaryPrecocity is particularly important for the economic production of intensively planted apple trees. Unfortunately some cultivars show a propensity for barewood on young trees, which limits early production on 2 year-old spur sites. The new cul

SummaryThe effect of gibberellin application on the process of appendage formation and ¯ower bud formation was studied in buds from light–flowering ‘Pacific Rose' apple trees. GA3 was applied at 300.mg l–1 on four dates from full bloom to eigh

Summary‘Pacific Rose’ trees in the light flowering year of a biennial bearing cycle were treated with GA3 or GA4+7 to investigate reducing flower bud formation. GA3 was applied at 300 mg l–1 in a time-course study starting at full bloom and end
