Reduced levels of calcium and other mineral elements in grapevine leaves affected by Bois noir (BN)
Natural Sciences and Mathematics
The concentrations of seven mineral elements (Ca, K, N, Mg, Mn, Fe and P) were analyzed in leaves of healthy gra- pevines and of grapevines infected with Bois noir (BN). The levels of calcium of all five varieties used in the study('Chardonnay', 'MuÈller Thurgau', 'Pinot Noir', 'Lagrein' and 'Zweigelt') were significantly lower in leaves infected with BN. The other six elements also showed a tendency towards decreased contents, but the effects were less consi-stent. A distinctive varietal influence on both visual symptoms of BN and mineral contents was observed, 'Chardon-nay' and 'Zweigelt' being the most susceptible cultivars.
