Abstract

SILVEIRA, Daniela Garcia et al. Effects of banana streak virus on the development of banana cultivars. Summa phytopathol. [online]. 2007, vol.33, n.2, pp. 190-191. ISSN 0100-5405.  http://dx.doi.org/10.1590/S0100-54052007000200015.

On this study, the BSV effects on five banana cultivars were evaluated under greenhouse conditions. Micropropagated plants of cultivars SH 3640, FHIA 18, Caipira, Thap Maeo and Pioneira were inoculated with BSV using mealybug Planacoccus citri Risso as a vector. Controls plants were inoculated with non-viruliferous mealybugs or not inoculated. Plant height, pseudostem diameter, number of leaves, foliar area and root and shoot dry mass were evaluated. Disease symptoms were first visible 15 days after plant inoculation with virus. Statistical differences were detected for the host growth variables evaluated. It was concluded that BSV affected significantly the growth of all studied cultivars.

Keywords : BSV; Badnavirus; Planacoccus citri; mealybug.
