Other claims from this paper (7)
- Intervention effect All fertilizer applications, particularly those with microelements, increased the expression of esca foliar symptoms in grapevine.
- Intervention effect Greater vegetative growth was detected only in vines treated with NPK fertilizers.
- Association The increase in foliar symptoms was always associated with a decrease of calcium in the leaf.
- Association The increase in foliar symptoms was associated with a decrease of magnesium in the leaf, to a lesser extent than calcium.
- Mechanism The authors suggest, as a hypothesis, that a hypersensitive reaction of the plant, given the role of calcium in defense, underlies the development of foliar symptoms.
- Observation The vineyards were in nutritional balance regardless of the fertilizer applications.
- Intervention effect Sugars in the musts decreased in asymptomatic treated vines.
