Última Biomass, virus concentration, and symptomatology of cucurbits infected by mild and severe strains of Papaya ringspot virus Scientia Agricola Pacheco,Davi Andrade; Rezende,Jorge Alberto Marques; Piedade,Sônia Maria de Stefano. 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 greenhouse conditions, sampled at 7, 14, 21, 28 and 35 days after inoculation (DAI), and analyzed by PTA-ELISA. The severity of the symptoms was scored according to a scale from 1 to 5, and the fresh and dry biomass of the aerial part of the plants...

Bras. Frutic. SACOMAN,NAYARA NIELE; VIANA,ALEXANDRE PIO; CARVALHO,VIRGINIA SILVA; SANTOS,EILEEN AZEVEDO; RODRIGUES,ROSANA. ABSTRACT Passion fruit (Passiflora edulis) is a fruit species of great relevance for Brazilian economy. However, it is highly susceptible to the Cowpea aphid-borne mosaic virus (CABMV). The species P.setacea, on the other hand, is resistant to the disease. The present study aimed to identify CABMV-resistant P. setacea genotypes for the introgression of genes into sour passion fruit genetic breeding programs. The seeds of passion fruit genotypes were germinated in vitro in MS culture medium. The seedlings were acclimatized in a growth chamber at the temperature of 27 ± 2ºC, photoperiod of 16:8 hours and 80% of relative humidity. Thirty plants of each genotype were mechanically inoculated with extract prepared from leaves collected from passion fruit plants...
