Abstract

The Bois noir (BN) disease induced by ‘Candidatus Phytoplasma solani’ (CPs) is common in European vineyards. Its damage has not been fully investigated, especially with regards to wine attributes. The impact of BN on yield, berry composition and wine characteristics of Vitis vinifera L. cv. ‘Chardonnay’ was therefore comprehensively characterized in a 3-year field experiment in Hungary, Eger winegrowing region. Additionally, the bindweed-related tuf-b1 genotype was identified to be involved in the BN pathosystem in the experimental vineyard. Infection of CPs tuf-b1 genotype resulted in severe yield loss, the average decrease in number of bunches and total yield per vine was 56.7% and 68.4%, respectively. Analyses of wines produced from grapes of BN infected vines revealed decreased alcohol, epicatechin and iron contents; and increased organic acids, titratable acidity, catechin and calcium contents. Sensory evaluation of these wines confirmed unfavourable characteristics, i.e. higher acidity, bitterness, and usually pinkish discolouration. Negative impact on berry composition and wine quality were pronounced in the vintage with favourable weather conditions for grapevine production, whereas the negative effects of BN infection were less prominent, even masked, in the vintages with unfavourable weather (wet and cool). To reduce BN-caused damage, the need for improved preventative and curative measures for BN disease is highlighted.
