Ocurrence and severity of mosaic vírus on passion fruit

The aim of this work was to evaluate the percentage of plants with symptoms of Cowpea aphid-borne mosaic vírus (CABMV) and the severity of the symptoms, in yellow passionfruit (Passiflora edulis Sims) grafted and not grafted. The experiment was carried out in Adamantina, SP, Brazil, from April 2006 to June 2007, adopting the experimental design in randomized blocks with four treatments and eight replicates. The studied factors were three rootstocks: Passiflora edulis, P. alata and P. gibertii, and plants not grafted. It was used the yellow passion fruit (Passiflora edulis Sims) as graft. The variables evaluated were: percentage of plants with symptoms of CABMV and the severity of the symptoms. The first plants with symptoms of CABMV occurred 90 days after planting in the field, reaching 180 days after planting 100% of plants with CABMV in P. alata and P. gibertii and 97,5% in P. edulis and in not grafted plants.
