KAYMAK, H. C., 2013. Effect of nitrogen forms on growth, yield and nitrate accumulation of cultivated purslane (portulaca oleracea l.). Bulg. J. Agric. Sci., 19: 444-449 The present investigation was carried out to determine not only the most appropriate nitrogen form but also the effect of these forms on growth, yield, element content and nitrate accumulation of cultivated purslane (portulaca ...

We used molecular phylogenetic and morphological data to reexamine the taxonomic status of Portulaca okinawensis (≡ P. pilosa subsp. okinawensis) endemic to the central Ryukyu islands, southwestern Japan. Our molecular analyses showed that P. okinawensis is monophyletic, sister to the clade of P. psammotropha and P. tuberosa and it is not closely related to P. pilosa subsp. pilosa. Two subclade...

objective(s) portulaca oleracea l. is a herbaceous weed from portulacaceae family. it can be found in many parts of the world. modern pharmacological studies have demonstrated that p. oleracea have antioxidant effects. the protective effect of aqueous and ethanolic extract of p. oleracea against cisplatin-induced renal toxicity was studied in rats. materials and methods single intraperitoneal i...

Streptomyces sp. produces bioactive compounds with a broad spectrum of activities. Streptomyces kebangsaanesis SUK12 has been identified as a novel endophytic bacteria isolated from ethnomedicinal plant Portulaca olerace, and was found to produce the phenazine class of biologically active antimicrobial metabolites. The potential use of the phenazines has led to our research interest in determin...

The Portulacaceae is one of the few terrestrial plant families known to have both C(4) and Crassulacean acid metabolism (CAM) species. There may be multiple origins of the evolution of CAM within the Portulacaceae but the only clear evidence of C(4) photosynthesis is found in members of the genus Portulaca. In the Portulaca, CAM succulent tissue is overlaid with the C(4) tissue in a unique fash...

Brinjal little leaf (BLL) is a widespread disease of phytoplasma etiology in India that induces severe economic losses. Surveys were conducted in eight brinjal-growing states of India during July 2014 to September 2015 and eighteen BLL samples showing little leaf, phyllody and witches' broom symptoms were collected for phytoplasma identification. Presence of phytoplasmas was confirmed in all th...
