Pollen discounting, a reduction in outcross success associated with increased selfing, was evaluated in the common morning glory Ipomoea purpurea. A field experiment was conducted to estimate selfing rates and outcross success using small arrays of plants with large or small anther-stigma distance (ASD). To evaluate the effect of genotypic composition on the mating-system parameters, arrays wer...

An optimal crossing distance exists within plant populations if inbreeding and outbreeding depression operate simultaneously. In a population of tetraploid Digitalis purpurea, maternal plants were pollinated with donors at four distances: 0 (self-pollination), 1, 6 and 30 m. Lifetime fitness of F1 progeny was investigated in greenhouse experiments, and significant inbreeding and outbreeding dep...

The present study was carried out to evaluate the effect of methanol and chloroform extracts of Bauhinia purpurea on experimentally induced excision, incision, burn and dead space wound models in Sprague Dawley rats. Formulations of methanol and chloroform extracts of Bauhinia purpurea were prepared in carbopol and simple ointment base at concentrations of 2.5% and 5% and applied to the wounds....

Background: The herbicide RoundUp® became widely used in agriculture in the mid-1990s. Current populations of the crop weed Ipomoea purpurea exhibit both resistance and tolerance to RoundUp, which are two types of defence that have previously been shown to have a genetic basis in this weed species. Questions: Did the genetic basis of RoundUp defence antedate the introduction of RoundUp? If so, ...

OBJECTIVE Dental caries, periodontitis and other mucosal diseases are caused by a complex community of microorganisms. This study aimed to investigate the antimicrobial properties of saponins of four important oil yielding medicinal plant extracts on selected oral pathogens that are involved in such diseases. MATERIALS AND METHODS Saponins were extracted from Bauhinia purpurea, Madhuca longif...

Objectives. One of the important causes of flap losses is ischemia-reperfusion damage. Arnebia species are rich in naphthoquinone derivatives which known to have anti-inflammatory and anti-oxidant effects. The aim of the present study was to investigate the effects of Arnebia purpurea extract on viability of the skin flaps. Methods. Eighteen Wistar rats were divided in three groups. Caudal-base...

Since years ago, phytopharmaceutical drugs have been used by various societies, as a traditional treatment. Echinacea purpurea (Asteraceae) is the best known of the dozen or so species of the genus Echinacea, a group of perennial prairie wildflowers native to the central grasslands of North American. E. purpurea is cultivated widely throughout the United states, Canada and Europe, although it h...
