Pollen grains from twelve species of the Passifloraceae family from the Brazilian Atlantic Forest were analyzed: Passiflora subg. Astrophea (1sp.), P.subg. Decaloba (1sp.) and P.subg. Passiflora (10spp.). The current study aims to acquire additional information and feature the pollen morphology of the herein studied species to help setting a more precise taxa delimitation. Acetolyzed pollen grains were measured, described and illustrated using light and scanning electron microscopy. The pollen grains were medium or large sized, oblate spheroidal, suboblate, prolate spheroidal and subprolate; 4-colpate (P. kermesina), 6-12-pantocolporate (P. mediterranea), 6-colpate (P. mucronata), 6-colporate (P. pentagona), 12-colporate (P. misera) or 6-syncolpate (in... |

Uma nova espécie de Passifloraceae é descrita e ilustrada, Passiflora mucugeana T.S. Nunes & L.P. Queiroz. Esta espécie é conhecida até o momento, na região da Chapada Diamantina, Bahia, em áreas próximas aos municípios de Mucugê, Ibicoara e Barra da Estiva, em áreas de florestas estacionais e campo rupestre (Complexo Espinhaço), chegando a uma altitude de 1.200 metros. Passiflora mucugeana é inserida no subg. Passiflora supersect. Stipulata Feuillet & MacDougal sect. Granadillastrum Triana & Planch., por apresentar caracteres morfológicos que a assemelham a P. imbeana Sacco. |

The characterization and viability of pollen grains are useful tools to guide crosses in breeding programs. The objective of this study was to describe the morphological patterns and viability of pollen grains from five accessions of Passiflora edulis f. flavicarpa O. Deg. and five accessions of Passiflora setacea DC. Pollen morphology descriptions were made using light microscopy and scanning electron microscopy, whereas the viability analysis was performed by in vitro germination and histochemical analysis (Lugol's solution and 2,3,5-triphenyltetrazolium chloride). Pollen grains assessed for germination were inoculated in culture medium containing Ca(NO3).4H2O (0.03%), Mg(SO4).7H2O (0.02%), KNO3 (0.01%), H3BO3 (0.01%), sucrose (15%) and agar (0.8%).... |

This work studied a new protocol for organogenic calli induction and characterization of the morphology and ultrastructure of callogenesis in leaf explants of Passiflora gibertii N. E. Brown, a native passion fruit species from Brazil. Calli induction was performed in different growth conditions (light and dark), different MS medium salt concentrations (MS and MS half strength) and the presence or absence of coconut water. The leaf explants maintained in the dark were more responsive to bud formation. In order to reduce spending on in vitro culture, the most suitable induction medium for P. gibertii organogenesis could, therefore be the MS half strength salt concentration medium maintained in the dark. The addition of coconut water to the culture medium... |

Leaves from several Passiflora species are largely employed in the Brazilian folk medicine as anxiolytic and sedative. In this work the anxiolytic, sedative-like properties and liquid chromatography analysis of methanolic extract of Passiflora actinia were evaluated. The methanol extract and all of its fractions presented significant sedative-like effect in elevated plus-maze and open field tests. Only the aqueous fraction of the methanol extract showed selective anxiolytic activity (30 mg/kg). Chromatographic analysis of the active fractions showed the presence of isovitexin and absence of the classical Passiflora beta-carboline alkaloids or flavonoids such as vitexin, rutin, swertisin, hesperidin and orientin. The tincture obtained from P. actinia leaves... |

The effects of inoculation of sweet passion fruit plants with the arbuscular mycorrhizal (AM) fungus Scutellospora heterogama on the symptoms produced by Meloidogyne incognita race 1 and its reproduction were evaluated in two greenhouse experiments. In the 1st, the M. incognita (5000 eggs/plant) and S. heterogama (200 spores/plant) inoculations were simultaneous; in the 2nd, the nematodes were inoculated 120 days after the fungal inoculation. In both the experiments, 220 days after AM fungal inoculation, plant growth was stimulated by the fungus. In disinfested soil, control seedlings (without S. heterogama) were intolerant to parasitism of M. incognita, while the growth of mycorrhized seedlings was not affected. Sporulation of S. heterogama was negatively... |
