The Effect of Climate Change on the Medicinal Plant Purslane (Portulaca oleracea).

Climate change is a form of stress to plants. Increased temperatures, drought and salinity are expected to have significant effects on the growth and chemical composition of medicinal plants. We have been investigating the effect of drought and salinity on the medicinal plant purslane, known for its high levels of important fatty acids and betalain pigments, using methods from both ecology and chemistry. Several genotypes of purslane were grown under various stress levels in a genotype by environment experiment. Plant growth and fitness were monitored via morphological parameters. The chemical response to stress was measured by a combination of single point measurements (e.g. antioxidant levels) and metabolomic approaches (spectroscopic methods such as visible spectra and IR spectra). We will report on the results to date.
