PURPOSE The antiseptic qualities of aromatic and medicinal plants and their extracts have been recognized since antiquity, while attempts to characterize these properties in the laboratory date back the beginning of the XX(th) century. In the current study essential oils obtained from Pelargonium roseum (Geraniacea) were analyzed for their antibacterial and antifungal activities. METHODS The ...

Crassulacean acid metabolism (CAM) is common in several plant families and is often associated with succulence. Few studies have examined the occurrence of CAM from a phylogenetic perspective. The genus Pelargonium is promising for such a study because members are characterized by dramatic variation in growth form (including geophytes, shrubs, and stem succulents) and because growth form divers...

ABSTRACT The objective of this work was to determine the composition and evaluate in vitro vivo effects essential oils (Lippia sidoides Cham., Ocimum gratissimum L., Cymbopogon citratus Stapf., selloi Benth., Citrus sinensis micranthum Willd., sp., Piper aduncum L.) on control Fusarium rot melon fruits, caused by fungus pallidoroseum. were obtained hydrodistillation their chemical determined GC...

BACKGROUND Natural products are proved to play a good role as an alternative to synthetic chemicals in clinical conditions. Previous studies showed that Pelargonium graveolens has anti-inflammatory and antifungal activity against Candida albicans. The aim of this study was to evaluate the efficacy of essential oil of Pelargonium graveolens in the treatment of denture stomatitis. MATERIALS AND...

Climate change is often assumed to be a major driver of biodiversity loss. However, it can also set the stage for novel diversification in lineages with the evolutionary ability to colonize new environments. Here we tested if the extraordinary evolutionary success of the genus Pelargonium was related to the ability of its species to capitalize on the climate niche variation produced by the hist...

The purpose of this study was to assess the possibility using compost made from post-consumer wood in zonal pelargonium (Pelargonium zonale) cv. ‘Tex Mex’ cultivation. influence on plant’s development and nutritional state, as well microbiological enzymatic activity substrate examined. Two variants marked with following letters: OPA OPB were used. Both consisted waste (OP) (70% weight) mixed po...

(63)Ni was applied to nonsenescent source leaves and found to be transported to sink tissues in pea (Pisum sativum L.) and geranium plants (Pelargonium zonale L.). The comparative mobilities (percent tracer transported out of source leaf /% (86)Rb transported) for (63)Ni in peas was 2.12 and in geranium 0.25. The value for the phloem mobile (86)Rb was 1.00. By contrast, the comparative mobility...

Absorption and reflectance spectra of maple (Acer platanoides), cotoneaster (Cotoneaster alaunica), dogwood (Cornus alba) and pelargonium (Pelargonium zonale) leaves with a wide range of pigment content and composition were studied in visible and near-infrared spectra in order to reveal specific anthocyanin (Anth) spectral features in leaves. Comparing absorption spectra of Anth-containing and ...

Metabolic conversion of l-galactono-1, 4-lactone and l-ascorbic acid to (+)-tartaric acid and oxalic acid has been studied in Pelargonium crispum, cv. Prince Rupert. Experiments with specifically labeled substrates suggest a path of conversion involving cleavage of l-ascorbic acid, or a metabolic product of l-ascorbic acid, between C(2) and C(3), such that oxalic acid arises from the two carbon...
