The edible species ofPassiflora

Genetic diversity in passion fruit (Passiflora spp.) evaluated by RAPD markers

“…The economical importance of some species is associated to the quality of the fruits for consumption and medicinal properties. The passion fruit is an allogamous plant and the edible fruit-producing species are diploids (2n=18), namely, the purple (P. edulis) and the yellow passion fruit (P. edulis f. flavicarpa) (Martin and Nakasone, 1970), which is cultivated in Brazil. The high interspecific compatibility in natural and artificial crossings among the diploid species leads to a wide genetic diversity distributed in different agro-climatic regions.…”

“…Morphological characters used for taxonomical description of passion fruit have allowed a classification up to the species level, but not to an intraspecific discrimination. Besides fruit color, flavor and resistance to diseases, P. edulis and P. edulis f. flavicarpa do not show contrasting differences (Martin and Nakasone, 1970). Although still not much used in passion fruit genetic variability studies, RAPD markers have been shown to be polymorphic, allowing the characterization of the variability among and within species as well as for the identification of hybrids and parentals (Fajardo et al, 1998, Cassiano, 1998Otoni et al, 1995).…”

Transgenic passionfruit expressing RNA derived from Cowpea aphid-borne mosaic virus is resistant to passionfruit woodiness disease

“…However, reports of a synergistic effect between PWV and Cucumber mosaic virus (CMV), family Bromoviridae, genus Cucumovirus, causing tip necrosis (Pares et al, 1985) have hindered the use of cross-protection. Breeding for resistance is complicated by self-incompatibility and inter-specific incompatibility in Passiflora species (Martin & Nakasone, 1970;Lopes, 1994;Bruckner et al, 2002). An interesting alternative control method would be the use of transgenic plants with pathogen-derived resistance (PDR).…”

Resposta do maracujazeiro amarelo (Passiflora edulis Sins var. flavicarpa Deg) a lâminas de irrigação e doses de adubação potássica.

“…Entretanto, ainda há necessidade de informações sobre as necessidades hídricas dessa cultura, de forma a possibilitar uma programação racional das irrigações. (Martin & Nakasone, 1970;Schultz, 1968;Medina et al, 1980). O maracujá amarelo é o mais conhecido, amplamente comercializado de norte a sul do país (Souza & Meletti, 1997).…”

“…As maiores limitações da cultura do maracujazeiro são climáticas (Martin & Nakasone, 1970), sendo responsáveis por grandes variações no ciclo produtivo do maracujá em diferentes localidades e épocas do ano (Veras, 1997 (Menzel & Simpson, 1989e Menzel & Simpson, 1994.…”
