THE INFLUENCE OF FUNGICIDES ON THE PHYSIOLOGICAL PROCESSES` INTENSITY IN MALUS DOMESTICA BORKH. ATTACKED BY PODOSPHAERA LEUCOTRICHA (ELLIS & EVERH.) E. S. SALMON

Abstract

In the analized leaves of the Malus domestica Borkh., it has been noticed that the photosynthesis and transpiration intensity vary, during the day, according to climatic conditions, presenting lower values in the morning, higher values in the afternoon and lower values towards the evening, but the recorded values are higher for the leaves plant after performing fungicide treatments, in comparison with the leaves plant attacked by Podosphaera leucotricha (Ellis & Everh.) E. S. Salmon (not treated with fungicide). At the leaves of the apple tree analysed after performing treatments with fungicide a higher water content and clorophyll content was registered, compared to attacked leaves by pathogen.
