摘要

In apple, synthetic cytokinin 6-benzylaminopurine (BA), either alone or combined with gibberellins 4+7 (GA_(4+7)), plays an important role in overcoming apical dominance and in the production of well-feathered apple nursery trees. The solutions of BAand BA+GA4+7 corresponding to the concentrations of 250, 350 and 450 pi 1"' of active ingredient (BA) were applied three times at 7-day intervals during vegetative period. Feather formation is strongly influenced by type and concentration of plant growthregulators. Increasing concentrations of BA and BA+GA4+7 led to a greater number of feathers, increased feather length, and expanded branching zone. Applied in combination with GA4+7, BA has stronger positive effect on total feather number, feather length, branching zone and tree height, than when applied alone. Compared to BA+GA4+7, BA has a stronger effect on the growth rate of the shoot, resulting in a greater feather angle and a lower tree height, which can be eliminated by addition of GA_(4+7)). The treatments also had different effects on trunk diameter. In Gala, a minor adverse effect of BA on trunk4+7diameter was noted, whereas it was positive in Jonagold.
