Survey of sour passion fruit cultivars commercialized in Brazil

Histological analysis of pollen-pistil interactions in sour passion fruit plants (Passiflora edulis Sims).

The success of sexual plant reproduction is directly influenced by specific interactions between the pollen and pistil. Light, fluorescence and scanning electron microscopy techniques were used to evaluate the steps of pollination in sour passion fruit plants (Passiflora edulis Sims). In the compatible interaction, pollen tubes grow through stigma projections towards the ovary. The pollen grain...

Genetic diversity in yellow passion fruit populations

The genetic diversity in yellow passion fruit genotypes from populations of different origins (Campos dos Goytacazes, Itaperuna and São Francisco de Itabapoana , Rio de Janeiro State, Brazil), was quantified. The following traits were evaluated in two environments (Macaé and Campos dos Goytacazes): fruit weight, mean number of fruits, fruit length, equatorial fruit diameter, rind thickness, bri...

Detection of a resistance gradient to Passion fruit woodiness virus and selection of 'yellow' passion fruit plants under field conditions.

Productivity of 'yellow' passion fruit (Passiflora edulis Sims. f. flavicarpa O. Deg.) is reduced by infection with Cowpea aphid-borne mosaic virus (CABMV). We examined resistance in 72 yellow passion fruit plants grown from open-pollinated commercial seed. Plants were mechanically inoculated with CABMV virus and maintained in the field in order to select contrasting genotypes for resistance. I...

Microbiological monitoring of mineral water commercialized in Brazil

The quality of mineral water commercialized in Brazil regarding the microbial content was analyzed and the results were compared with the standards established by the current legislation. Results demonstrated there was no bacterial contamination, but several types of fungi were found. Therefore, bottled mineral water could be considered a possible route for the transmission of filamentous fungi...
