| Com o objetivo de avaliar o efeito de épocas de poda sobre características agronômicas da mandioca foi conduzido este experimento na área experimental da Universidade Estadual do Sudoeste da Bahia, em Vitória da Conquista - BA, usando delineamento experimental em blocos casualizados, com 13 tratamentos, sendo 1 tratamento sem poda e 12 épocas de poda, realizadas a partir de junho de 2008 (213 dias após o plantio) até junho de 2009 (543 dias após o plantio), com intervalo de 30 dias entre as podas e 3 repetições. As características avaliadas foram: produtividade da parte aérea, produtividade de raízes tuberosas, massa seca em raízes tuberosas, porcentagem de amido em raízes tuberosas, rendimento de farinha e produtividade de farinha. A adoção da poda em... |

| The Passion fruit woodiness virus (PWV) is the most important virus affecting passion fruit (Passiflora edulis f. flavicarpa Deg.) crops in Brazil. The main purpose of this work was to select mild strains of PWV and to evaluate their protective effect against a severe strain of the virus. Three mild strains were selected from outstanding plants found in orchards severely affected by the virus (F-101, F-102 and F-103) and three others were obtained from blisters formed in passion fruit vine leaves showing mosaic (F-99, F-144 and F-145). The protective effect of the mild strains was evaluated for vines under greenhouse and field conditions. Plants pre-immunized with mild strains F-101, F-102 and F-144, in a greenhouse, had partial protection against the... |

| ABSTRACT: Severe mosaic symptoms, accompanied by yellow spots, abnormally small leaves, fruit malformation and cracking, reduced plant growth, and high levels of whitefly (Bemisia tabaci MEAM1) infestation were observed in passionflower (Passiflora edulis) orchards in southwestern Bahia, Brazil. The aim of this work was to identify the species of begomovirus infecting the passionflowers, its prevalence in southwestern Bahia, and the spatial and temporal dynamics of the disease. Leaf samples from symptomatic plants collected at 57 orchards located in ten counties were evaluated by PCR for begomovirus infection. Complete nucleotide sequences of DNA-A for two isolates revealed 97 % identity with Passionfruit severe leaf distortion virus (PSLDV). The... |
