Abstract

: Viticulture is one of the most produced fruit crops in the world; therefore, challenges of cropping systems are very relevant. Altered environments pose an obstacle; in addition, climate change influences plant-pathogen relationships and their risks. This work described the interaction of Neophysopella tropicalis (Ono) x 'Cabernet Sauvignon' grapevine at 25 and 30 degrees C, from an epidemiological and anatomical perspective. Rust severity showed no differences in plants kept at 25 and 30 degrees C; however, a significantly higher number of rust pustules was observed at 30 degrees C. The accumulation of phenolic compounds in healthy leaves at 25 degrees C was denser and more homogeneous than in the other treatments. The phenol pattern alteration observed in healthy leaves at 30 degrees C is possibly related to the larger number of lesions observed at this temperature. (AU)
