AbstractRooted leaves from 15 sweet potato cultivars or lines were grown in small pots in four environments, greenhouse plus three environments which were considered stressful: full sun in small pots, partial shade, and flooding of roots. The effects of the three stress environments were observed in eight characteristics. Each stress situation reduced storage root production and produced characteristic responses. Cultivars differed in their response to each stress. Some cultivars, especially "Gem" and "Jaspar," were more productive and less influenced by stress than all others.
