Environmental factors influencing inflorescence flower number of Marlborough Sauvignon Blanc
Brief:Flower number per inflorescence
is an important yield parameter, yet the factors controlling
the extent of branching on the developing inflorescence
remain elusive. Temperatures and carbohydrate concentrations
in the vine at bud break have both been implicated,
together with the position of the inflorescence on the
developing shoot.
Changes in shoot development, potentially induced by
differences in spring carbohydrate reserves, may alter
fruit-set. Investigating fruit-set on shoots with different
leaf areas forms the second part of this project.
