[Autom. eng. transl.] Climate change is affecting Italian wine production. The incidence of multiple summer stresses is increasing in many areas and can compromise the productivity of the vineyards, as well as the achievement of an optimal composition of the grapes at harvest. The first reaction of the vine to the decrease of the water resource is the limitation of the normal photosynthetic and transpiration rates. The leaves, thanks to transpiration, are the most efficient plant organs in regulating their temperature. However, if the transpiration rates are drastically reduced due to a prolonged drought, the leaves lose this capacity and their temperature can rise even beyond 40 ° C. In such situations the appearance of yellowing of the most exposed leaves is frequent, which lose their ability to recover full photosynthetic rates even after the subsequent restoration of non-limiting conditions. Kaolin is active in reducing such stressful situations.
