Abstract: Pre-immunization with mild strains of Papaya ringspot virus -type W (PRWV-W) has allowed the mosaic disease to be controlled in different cucurbit species, with increases in marketable fruit yield. The objective of this study was to compare virus concentration, biomass and symptomatology of 'Caserta' zucchini squash, 'Menina Brasileira' long-neck squash and 'Crimson Sweet' watermelon plants infected by three mild strains and one severe strain of PRSV-W. Plants were inoculated at the cotyledonary stage, under g… Show more

“…For instance, interactions between PNRSV-Prunus spp. (Moury et al 2001) and PRSV-Cucurbita mochata (Pacheco et al 2003) did not lead to any correlation, probably because some viral isolates accumulated to a high titre in plants, but induced only few or no symptoms. This poses an important methodological problem, as discussed further in the last section.…”

“…Consequently, virus accumulation increases virulence and virus transmission to another host. Studies performed with Papaya ringspot virus strains in zucchini squash, squash and watermelon plants (Pacheco et al, 2003) associated viral multiplication and symptom severity. In addition, analysis of different strains of cucumber vein yellowing virus (CVYV) demonstrated that severe strain CVYV-Jor accumulated earlier than mild strain CVYV-Alm1 (Galipienso et al, 2013).…”

“…Losses were less when inoculations occurred later in the season. Pacheco et al (2003) observed that biomass was reduced up to 74% when measured 40 d after cotyledons of squash (C. pepo) were inoculated with a severe strain of PRSV compared with being inoculated with a mild strain of PRSV. 'Menina' (likely the same C. moschata cultivar used in our study) did not show any differences when inoculated with severe vs. mild strains of PRSV.…”
