Describes a technique for inducing premature bursting of Sultana buds that would otherwise go through winter dormancy.
Prior techniques had required removal of lateral shoots and growing points, however other research indicated premature bud burst could be achieved with growing points still intact.
The experiment resulted in premature bud burst in 55 out of 72 vines involved, with an average of three premature bud bursts per vine on those where premature bursting occurred.
The observations were in line with the previous hypothesis that bud burst inhibitor is produced in growing points and young leaves.
Contrary to previous research they were able to achieve premature burst in bud older than six weeks and bud burst was not confined to terminal positions.
