BOARI, Alessandra de Jesus et al. Coffee ringspot virus (CoRSV): influence on the beverage quality and yield of coffee beans. Summa phytopathol. [online]. 2006, vol.32, n.2, pp. 192-194. ISSN 0100-5405. http://dx.doi.org/10.1590/S0100-54052006000200018.
Coffee ringspot virus (CoRSV), transmitted by the tenuipalpid mite Brevipalpus phoenicis, has been found in high incidences in several regions of the state of Minas Gerais. It induces chlorotic spots on the leaves and fruits and may induce severe fall of the leaves with implication in the yield. An evaluation was made on the effects of CoRSV-infected coffee berries on the beverage quality as well as on the weight of the beans. Infected beans had less reducing sugars and presented an increase in the electrical conductivity. The quality of the beverage prepared from infected fruits was lower than that of healthy fruits. There was a reduction of about 5% in the weight of beans from infected fruits.
