摘要：

Reducing light intensity to 1800 ft-c was more than compensated by raising CO2 concentration about 50% above current ambient levels. Since ambient CO2 may rise by 50% within 50 yr, while light intensities are not likely to drop to 1800 ft-c, the combined effect will permit rates of net phostosynthesis to rise above present levels. [Pinus attenuata, P. coulteri and Quereus chrysolepis are discussed.].
