Abstract

The common purslane plant (Portulaca oleracea L.) flowered and produced seeds throughout the growing season. Seeds were mature about 15 days after flowering. Increased light intensity and temperature stimulated growth. In general greater yields were obtained under cool white light, followed by yields under green, blue, red, and yellow light, in that order. With high temperature during the light period and low temperature during the dark period, best growth occurred under green light.
