Abstract


The research regarding physiological modifications produced by Stigmina carpophila (Lév.) M.B.Elliswas performed in Prunus avium L. cultivated in the climatic conditions in Oltenia region.

In the leaves of the Prunus avium L. attacked by Stigmina carpophila (Lév.) M.B.Ellisis observed that the photosynthesis and transpiration intensity is similar to that in healthy leaves, but the recorded values are lower as a result of the reduction of the assimilation surface due to the formation of spots and necrosis on the leaves. The water content has lower values in the leaves of plants attacked by the pathogen, fact highlighted by the withering and drying of the leaves and the chlorophyll content also has lower values, which is correlated with the intensity of photosynthesis.
