Abstract

The researches regarding physiological modification produced in Persica vulgaris Miller due to the attack produced by Taphrina deformans (Berk.) Tul. were performed on Champion variety cultivated in the climatic conditions in Oltenia Region.

In the leaves of the peach attacked by the pathogen it is observed that the physiological processes intensity presents specific variations due the damaging action of the pathogen and of the climatic conditions. The photosynthesis and transpiration`s intensity in the attacked leaves is similar to that in the healthy leaves, but the recorded values are lower due to the reduction of the assimilation surface of the leaf due to the appearance of reddish-yellow spots and tissue deformation. The attacked leaves present a decrease of chlorophyll and water content, fact manifested by withering and drying of the leaves.
