Influence of the attack of the fungus Polystigma rubrum (pers.) dc (red leaf spot) on nutritional value of fruits in different plum cultivars

Abstract

This paper carried out of the influence of Polystigma rubrum attack on the soluble and insoluble glucides content in the plum cultivars, with different degrees of resistance to fungus attack: Poroabe and Vinete româneşti (sensitive cultivars), Renclod violet and Grase româneşti (middle-resistant cultivars) and Renclod verde (resistant cultivar), during the year 2008. Analyzing the results we observed that soluble glucides and insoluble glucides content with one exception was higher in healthy fruits comparatively with the attacked fruit. In generally, glucides was low in attacked fruit, but cannot establish a correlation between glucides content and the degree of resistance of the plum cultivars to attack of Polystigma rubru
