to study allelopathic effects of iranian walnut (juglans regia l.) on germination and initial growth of purslane (portulaca oleracea) and redroot pigweed (amaranthus retroflexus) an experiment was conducted in shahed university. the result showed that fresh leaf had negatively effected on radicle length. also, with increasing extract concentrations of persian walnut, the seed germination and se...

in order to evaluate the density and dry weight of weeds and seed and oil yield of castor bean ricinus communis l.) as a medicinal plant affected by cover crops, an experiment was conducted at the agricultural research station, faculty of agriculture, ferdowsi university of mashhad, during growing season of 2008-2009. treatments were four cover crops included white clover, fenugreek, hairy vetc...

INTRODUCTION Purslane (Portulaca oleracea L., Portulacaceae) is eaten extensively as a potherb, and added in soups and salads around the Mediterranean and tropical Asian countries (Fig. 1). There is a newer interest in cultivation of purslane as a crop since its identification as one of the best sources in the plant world for omega-3 fatty acid, α-linolenic acid (LNA). LNA is a precursor of a s...

To evaluate the potential of producing purslane (Portulaca oleracea L.) as a sodium (Na)-removing vegetable hydroponically at moderate NaCl salinity, two cultivars (Green and Golden) were grown in solutions with added 0, 6, 8, and 10 mM NaCl (the actual Na concentrations ’2, 8, 10, and 12 mM, respectively). At harvest, 26 days after transplanting, apparent growth and biomass accumulation were n...

Induction of GLUT4 translocation in the absence of insulin is considered a key concept to decrease elevated blood glucose levels in diabetics. Due to the lack of pharmaceuticals that specifically increase the uptake of glucose from the blood circuit, application of natural compounds might be an alternative strategy. However, the effects and mechanisms of action remain unknown for many of those ...

Purslane (Portulaca oleracea L.) is an important plant naturally found as a weed in field crops and lawns. Purslane is widely distributed around the globe and is popular as a potherb in many areas of Europe, Asia, and the Mediterranean region. This plant possesses mucilaginous substances which are of medicinal importance. It is a rich source of potassium (494 mg/100 g) followed by magnesium (68...

Wood vinegar, a by-product of wood pyrolysis, is mostly discarded. vinegar has phytotoxic effect and could be potentially used as naturally derived herbicide for weed control. The objective this research was to evaluate the efficacy from pyrolysis apple (Malus × domestica Borkh.) tree branch wastes control weeds. concentrations required inhibit 50% motherwort (Leonurus cardiaca L.), redroot pig...

13 selected purslane accessions were subjected to five salinity levels 0, 8, 16, 24, and 32 dS m(-1). Salinity effect was evaluated on the basis of biomass yield reduction, physiological attributes, and stem-root anatomical changes. Aggravated salinity stress caused significant (P < 0.05) reduction in all measured parameters and the highest salinity showed more detrimental effect compared to co...

Purslane (Portulaca oleracea) is a globally-distributed plant with a long history of use in folk medicine and cooking. We have developed purslane as a model system for exploring plant responses to stress. We exposed two varieties of purslane to saline stress with the objective of identifying differences between the varieties in the plasticity of morphological and physiological traits. The varie...

Common purslane (Portulaca oleracea L.) is an annual weed rich in omega-3 fatty acids which is consumed for its edible leaves and stems. In the present study six different genotypes of common purslane (A-F) were evaluated for their nutritional value and chemical composition. Nutritional value and chemical composition depended on genotype. Oxalic acid content was the lowest for genotype D, where...
