Combined effect of basalt dust foliar distribution and water availability on leaf morpho-physiological traits and grape quality in Falanghina

The aim of this work is to evaluate the effects of the application of basalt dust on the leaf surface of Vitis vinifera L. subsp. vinifera 'Falanghina' grapevine, grown under two different water availability levels over two years characterized by different climatic conditions. The experiment was conducted between 2021 and 2022 in a commercial vineyard of La Guardiense farm at Guardia Sanframondi (Benevento, southern Italy), in the Sannio wine district.
