MODIFICATIONS IN GAS EXCHANGE OF COMMON BEAN PLANTS INFECTED BY PATHOGEN COLLETOTRICHUM LINDEMUTIANUM

摘要

Anthracnose is a disease promoted by the pathogen Colletotrichum lindemuthianum that attack Phaseolus vulgaris plants. This fungus under favorable conditions as high temperature and humidity can infect common bean crop in all growth stages (Broughtonet al., 2003). In addition, this pathogen causes morphological, physiological and biochemical alterations that has been previously described in Phaseolus vulgaris, such as the significant decrease in photosynthetic pigments (Lobato et al., 2009a), photosynthesis rate, and consequent yield reduction (Goncalves-Vidigal et al., 2009).
