Performance of purslane biomass production (Portulaca oleracea) under different organic substrate concentrations

Vegetative Reproduction Potential of Common Purslane (Portulaca oleracea)

the response of purslane (portulaca oleracea) production and quality to different organic and chemical fertilizers

background and objectives: although chemical fertilizers in short-term can increase vegetables yield, but must be renewed each planting season that this trend increases the concentration of nitrate in the vegetables shoots, nitrogen leaching and contamination of water resources, loss of beneficial insects and microorganisms and soil fertility will decline, and over time reduce the yield and qua...

Evaluation of Antioxidant Properties and Mineral Composition of Purslane (Portulaca oleracea L.) at Different Growth Stages

The main objective of this research was to appraise the changes in mineral content and antioxidant attributes of Portulaca oleracea over different growth stages. The antioxidant activity was measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH), ferric-reducing antioxidant power (FRAP) assays. The iodine titration method was used to determine the ascorbic acid content (AAC). DPPH scavenging (IC(5...

effect of different sources and rates of nitrogen fertilizer on the growth and biomass production of purslane (portulaca oleracea)

in order to evaluate the effect of different sources and rates of nitrogen the growth and biomass production of purslane, a randomized complete block design was conducted with three replications at the agricultural research farm of shahrekord university in 2012. fertilization treatments were consisted of control (no n amendment), 30 and 90 kg n ha-1in the form of urea fertilizer, 30 and 90 kg n...

Effect of Salinity on Biomass Yield and Physiological and Stem-Root Anatomical Characteristics of Purslane (Portulaca oleracea L.) Accessions

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...
