Vegetative growth measured after leaf fall and clusters per shoot of Semillon grapevines following manipulation of the postharvest canopy efficiency.

	Trunk circumference (cm)		Cane number		Cane wt (g)		Clusters/shoot

^aMeans separated within columns using Fisher’s LSD test. Different letters within a column indicate a significant difference (p = 0.05).
^bAll fruit removed at midripening, therefore yield could not be determined at harvest 2002.
^c, , **, and ns indicate significance at p < 0.05, < 0.01, < 0.001, and not significant, respectively.
