Common purslane

Main weeds in maize field purslane, common amaranth, Asian copperleaf, white eclipta DAT is day after treatment. Weed numbers were counted at 30 DAT and weed plants were cut from ground level and immediately weighed at 30 DAT at different rate as percentage change compared to that of the untreated control. Each treatment had four replications, values are the average of four replicates... 

Both lantana and common purslane are weed pests in some crops. Common purslane root exudates inhibited soybean growth but showed stimulation in other bioassays reported in this paper. This may be a concentration and bioassay species dependent effect, since the effect of any toxin varies according to concentration and bloassay species (12). Lantana root exudates showed the strongest inhibitory effect on soybean growth of any of the species tested. Lantana is not found in soybean fields but is a weed pest in some areas in citrus orchards. Holm (13) included lantana, johnsongrass, and cogongrass in his list of the worst weed pests in the world. 

The effect of applied plant residues can be positively influenced by an increase of temperature. Mallek et al. (2007) established that dried and milled crop residues of onion (Allium cepa L.) or garlic (A. sativum L.) were able to reduce seed germination of barnyard grass (E. crus-galli (L.) R Beauv.), common purslane (Portulaca oleracea L.), london rocket (Sisymbrium irio L.) during their decomposition in soil, but only at the elevated (39°C) soil temperature. It can support combination of methods for weed control, in this case allelopathy with soil heating treatments (e.g., solarization). 

Masabni et al (1996) identified a Ser264 to Thr (threonine) mutation in a resistant biotype of common purslane. This conferred a high level of resistance to atrazine and also to linuron, a substituted urea herbicide. This was the first report of a Ser264 to Thr substitution in higher plants selected under field conditions. Previously, this mutation had only been selected through tissue culture in tobacco and potato (Sigematsu et al, 1989 Smeda etal, 1993). 

Portulaca oleracea commonly known as purslane belongs to the family Portulacaceae and is an herbaceous cosmopolitan weed. P. oleracea is one of the major sources of omega-3 fatty acids and was found to produce beneficial effects on cholesterol and triglyceride levels in heart disease and in strengthening the immune system. The plant also possesses marked antioxidant activity (Reid, 1986 Chevallier, 1996 Hocking, 1997).

The sunflower is also an allelopathic plant, and a sunflower extract was found to inhibit the growth of such common weeds as jimsonweed, velvetleaf, johnson-grass, curly dock, red sorrel, ragweed, purslane, smartweed, wild mustard, and lamb s-quarter. (Creosote bush, or chaparral, may be the outstanding example of an allelopathic plant. No other plant can live next to or under a creosote bush.)... 

To identify the zoospores motility inhibitory principles from the common purslane, Portulaca oleracea, 1.15 kg of fresh roots were first extracted with MeOH and then subjected to chemical fractionation using n-hexane, diethyl ether and EtOAc (Scheme 1) [83]. The diethyl ether extract (1.72 g)... 

Purslane is commonly consumed as a vegetable in many regions of the world (Ezekwe et al. 1999 Omara-Alwala et al. 1991).
