RT Journal Article SR Electronic T1 Clonal and Pruning Effects on Muscat à petite grains blanc Yield and Terpene Concentration JF American Journal of Enology and Viticulture JO Am J Enol Vitic. FD American Society for Enology and Viticulture SP 149 OP 152 DO 10.5344/ajev.1992.43.2.149 VO 43 IS 2 A1 M. G. Mccarthy YR 1992 UL http://www.ajevonline.org/content/43/2/149.abstract AB Significant differences in yield between 10 clones of Muscat à petite grains blanc were found when assessed over four harvest years. A Barossa Valley selection (73/10) was the highest yielding, and a California selection (I.S. 75.2221) the lowest due to significantly fewer bunches per vine. Spur-pruning increased the yield of four clones compared with cane pruning. Pruning method had no effect on the weight of annual prunings removed. There was no difference in the free volatile terpene concentration (FVT) between clones, but there were significant differences in potential volatile terpene concentration (PVT). PVT differences were not related to either fruit yield or maturity. Pruning method had no significant effect on PVT concentration.
