Sweet cherry (<i>Prunus avium</i> L.) is an important crop, which is very sensitive to abiotic stress. Known primarily for its fruits, its leaves are also rich in bioactive substances, which, however, still have no commercial value. There are no studies about the effects of GB exogenous application on biochemical parameters of sweet cherry leaves and few studies about effects in sweet cherry tree physiology. This study was conducted in a Portuguese sweet cherry commercial orchard. <i>Lapins</i> sweet cherry trees were treated with a commercial product based on GB, at two different concentrations (0.25% and 0.40%).
