Growth and nutritional quality comparison between two common purslanes, Portulaca granulatostellulata and P. edulis

Portulaca granulatostellulata and P. edulisare two subspecies ofcommon purslane. The biomass of both plants was similar; however, with long upright stems and a long vegetative period, P. edulis production was easier. Both subspecies were rich in vitamin C and flavonoids, main organic nutrients’ contents in 25-d-old plants were higher than those in15-d-old plants, and were higher in P. granulatostellulata.
