Nowadays, agronomic practices are evolving towards a “Sustainable Agriculture” using environmentally friendly systems. Modern viticulture aims to reduce inputs without reducing grape yield and wine quality. As a result of pruning, vine-shoots are generated as the waste of the vineyard. However their aqueous extracts have shown to have significant contents of bioactive compounds and, therefore, biostimulant activity. The foliar applications of vine-shoot extracts onto white grapevine variety caused a reduction in the sugar content, further an effect on the grape reaction product (trans-GRP) content was observed.
