Abstract/Contents:"Studies were initiated to determine the effects of different temperature regimes on triazine resistant and susceptible biotypes of common lambsquarters (Chenopodium album L. #2/ CHEAL) and smooth pigweed (Amaranthus hybridus L. #AMACH) from different geographical locations. These studies were conducted at the North Carolina State University Phytotron facility in controlled environment growth chambers. Triazine resistant common lamgsquarters biotypes from Virginia, Maryland, and Switzerland as well as a smooth pigweed biotype from Virginia were examined. Triazine susceptible biotypes of common lambsquarters and smooth pigweed were included as controls. Shoot height, weight, chlorophyll a and b content, and whole leaf fatty acid content of common lambsquarters and smooth pigweed were determined at 18/14 C, 26/22 C, and 36/26 C. Measurements of shoot height were made at 30 and 63 days after planting. The shoot weight, chlorophyll a and b content, and fatty acid content was determined from plants harvested at 63 days after planting. These data indicate common lambsquarters biotypes from different geographical regions exhibited a differential response to temperature. There was no difference between triazine resistant and susceptible biotypes in response to temperature. Differences were detected between triazine resistant smooth pigweed biotypes which indicated that the susceptible biotypes were more vigorous as indicated by shoot height and weight at lower temperatures than triazine resistant biotypes of smooth pigweed."
