Observações fenológicas fornecem informações sensíveis para a determinação de como as espécies de plantas respondem às condições climáticas regionais, visando à produção de frutas em diferentes regiões. Assim, o experimento foi conduzido de setembro de 2010 a janeiro de 2011, com o objetivo de caracterizar os estádios fenológicos de pereiras Housui e Kousui, cultivadas em clima semiárido do Nordeste do Brasil. Os dados fenológicos (fases) foram coletados no pomar, em observações diárias, desde a aplicação de cianamida hidrogenada (para a quebra de dormência) até o amadurecimento das frutas. Concluíu-se que, em clima semiárido, as pereiras Housui e Kousui concluem seus ciclos fenológicos em 128 dias e 115 dias, respectivamente. Novas pesquisas e mais alguns anos de avaliação serão necessários para gerar um sistema de produção de peras no semiárido nordestino. |

Passion fruit woodiness caused by the Cowpea aphid-borne mosaic virus (CABMV) is one of the main problems associated with the cultivation of passion fruit in Brazil. Identifying sources of resistance in Passiflora collections is the first step to develop resistant varieties. The objective of this study was to screen some Passiflora genotypes for CABMV resistance, as well as to evaluate foliar anatomical aspects associated with this viral infection. Eighty genotypes belonging to 12 Passiflora species were evaluated in a completely randomized block design with treatment in a factorial scheme (80 genotypes×7 evaluations). Artificial inoculation with CABMV was performed twice every four days. At 55 days after inoculation (DAI), the symptoms were evaluated through a scale of scores, which was then used to estimate the severity based on the disease index (DI%). The DI values for the different genotypes were grouped using the Scott-Knott test (p?.05) and multivariate analysis. The viral infections were confirmed by RT-PCR analysis. The genotypes BGP014, BGP112, BGP134, BGP143, BGP152, BGP170, BGP238, BGP077 and BGP413, belonging to the species Passiflora suberosa, P. malacophylla, P. setacea, and P. cincinnata, were considered resistant (0.00% DI). The disease caused by CABMV was more drastic in P. edulis, resulting in changes in the constitution and organization of vascular bundles of the leaf blade, with irregular arrangement of xylem and phloem elements, as well as spongy parenchyma cell hypertrophy. The wild species presented minor anatomical foliar alterations after inoculation with CABMV, particularly P. suberosa, P. setacea, and P. malacophylla, which did not present any changes after inoculation. The difference in the severity of CABMV among genotypes for resistance to the CABMV opens new perspectives for crossing these genotypes as parents in order to incorporate resistance to CABMV in passion fruit.
