Technical Abstract:
This article covered our preliminary findings on the influence of rootstock and vineyard floor management practices upon 'Cabernet Sauvignon' grape yeast assimilable nitrogen (YAN). Grapes were analyzed for YAN from two rootstocks (110R, high vigor; 420A, low vigor) and three vineyard floor management regimes (mowed then tilled resident vegetation – usual practice in California, and barley cover crops that were either mowed or tilled). Our initial results showed that rootstock choice had a greater affect on grape YAN than either of the three vineyard floor management practices.
