Interspecific hybrids can be studied using methodologies in which the male gamete with high reproduction potential, viability, and fertility is prioritized. Passiflora species, lush, showy, exotic colors, have great potential for ornamental plant market. In addition, artificial were developed without many difficulties because of weak reproductive barriers. Thus, meiotic post-meiotic behaviors a...

Interspecific crosses between the more than 520 Passiflora species may or not be compatible. The sequences ITS, matK, psbA-trnH, rbcL and trnL-F were used to confirm identity estimate genetic distances among 48 accessions of a germplasm bank. Twenty for within distinct subgenera. phylogenetic resolution based on ITS data was superior that any single chloroplast marker, recommending it as DNA ba...

Abstract Sweet passion fruit (Passiflora alata Curtis) is a species native to Brazil that economically important for consumption and can also be used as an ornamental plant. The objective of this work was evaluate different forms storing Passiflora seeds the purpose preserving accessions in germplasm banks. Three experiments were performed. In first, without aril stored two periods (one three y...

The genus Passiflora L. is the most representative of Passifloraceae, with over 500 known species, among which 150-200 originated from Brazil. In addition to the great commercial importance of this genus for the fruit market, many of the species have exotic flowers with a huge diversity of colors and can thereby be exploited as ornamental plants. This study was aimed at investigating the transf...

The petroleum ether and chloroform fractions of ethanol extract of leaf and stem from the plant Passiflora edulis (Fam: Passifloraceae) was subjected to antioxidant, antibacterial and cytotoxic activity. All the fractions showed potent antioxidant activity, of which the chloroform and petroleum ether fraction of stem demonstrated the strongest antioxidant activity with the IC50 value of 51.28 μ...

There may be many factors contributing to reduction in longevity and productivity in passion fruit plants, especially diseases of viral, bacterial or fungal etiologies, among which passion fruit woodiness, bacterial spot, root and collar rot, fusarium wilt, anthracnose and scab are the most important. The incidence of woody fruits in young plants totally compromises the productivity and quality...

BACKGROUND Passion flower (Passiflora incarnata) is used in traditional medicine of Europe and South America to treat anxiety, insomnia and seizure. Recently, it has shown antianxiety and sedative effects in human. METHODS In this study, anticonvulsant effects of hydro- alcoholic extract of Passiflora, Pasipay, were examined by using pentylentetrazole model (PTZ) on mice. Pasipay, diazepam, a...

We estimated genetic parameters through multivariate analysis of two species of Passiflora and their hybrids, considered of ornamental potential, based on the morphological characteristics: flower diameter, corona diameter, corona filament size, flower peduncle length, petal length and width, sepal length and width, internode length, stem diameter, leaf length, leaf width (mm), and leaf ar...
