A comparison was made of the germination, growth, and leaf CO 2 ‐exchange rates of redroot pigweed ( Amranthus retroflexus L.) and common lambsquarters ( Chenopodium album L.) under varied temperature regimes. It was found that redroot pigweed had greater rates of germination, growth, and CO 2 ‐exchange rates at high temperatures, whereas common lambsquarters performed better at low temperatures. The implications of such characteristics for competition between these species of weeds and their effect on crops are discussed.
