Recurrent polymorphic mating type variation in Madagascan Bulbophyllum species (Orchidaceae) exemplifies a high incidence of auto-pollination in tropical orchids
The transition from outcrossing to self-fertilization is one of the most common evolutionary changes in angiosperms. The orchid family exemplifies this evolutionary trend but, because of a general lack of large-scale surveys on auto-pollination in orchid taxa, the incidence and modes of auto-pollination among (sub)tropical orchids remain poorly known. In the present study, we assessed the frequ...
متن کاملAntibacterial Effect of Bulbophyllum Neilgherrense Wt. (orchidaceae). an in Vitro Study
The antibacterial activity of Bulbophyllum neilgherrense was tested against five species of bacteria, viz., Escherichia coli, Staphylococcus aureus, Bacillus pumilus, Pseudomonas aeruginosa and Pseudomonas putida Aqueous, ethanolic and chloroform soluble extracts of leaf and pseudobulb (5.50 w/v) were screened for their antibacterial potential. The zone of inhibition was seen to be largest when...
متن کاملMolecular phylogenetics and the evolution of fruit and leaf morphology of Dichaea (Orchidaceae: Zygopetalinae).
BACKGROUND AND AIMS The orchid genus Dichaea, with over 100 species found throughout the neotropics, is easily recognized by distichous leaves on long stems without pseudobulbs and flowers with infrastigmatic ligules. The genus has previously been divided into four sections based primarily on presence of ovary bristles and a foliar abscission layer. The aim of this work is to use DNA sequence d...
متن کاملVARIATION IN LEAF MORPHOLOGY OF PARROTIA PERSICA ALONG AN ELEVATIONAL GRADIENT IN EASTERN MAZANDARAN PROVINCE (N. IRAN)
In order to investigate the variation within and among populations of Parrotia persica C.A. Meyer based on leaf morphological traits, three populations were selected from Behshar area, in the east of Mazandaran Province. The populations selected along a transect in different altitudes of 182, 340, 540 meter above the sea level, respectively. In each population, 10 trees were selected and some l...
متن کاملLip anatomy and its implications for the pollination mechanisms of Bulbophyllum species (Orchidaceae).
BACKGROUND AND AIMS The lip structure of six Brazilian and one Asiatic species of Bulbophyllum with wind-assisted fly pollination (B. involutum, B. ipanemense and B. weddellii) and non-wind-assisted fly pollination (B. epiphytum, B. glutinosum, B. regnellii and B. rothschildianum) was studied to investigate the presence of secretory tissues related to these pollination mechanisms. METHODS The...
