摘要

The carbon dioxide concentration of the earth's atmosphere is increasing and expected to double some time during the middle of the next century. In addition, climate models predict that due to the ''greenhouse effect'', increased atmospheric CO(sub 2) may cause a warming of the earth's surface of 1.5 to 4.5(degree)C. The separate effects of atmospheric CO(sub 2) concentration and temperature on plant processes has been studied extensively. In general, a doubling of CO(sub 2) results in about a one-third increase in productivity of C(sub 3) plants, although a wide range of responses have been reported. This report reviews research concerned with the CO(sub 2) by temperature interaction effects on plants, with an emphasis on experiments conducted in outdoor, CO(sub 2)-enriched environments. 102 refs., 28 figs., 4 tabs.
