Foliar spray applications of 40% aqueous methanol were made to sunlit leaves of sour orange trees that had growh continuosly in clear-plastic-wall open -top enclosures maintaned out-of-doors at Phoenix, Arizona, for over 5.5 years in ambient air of approximately 400 micra mol mol-1 CO2 and in air enciched with CO2 to a concentration of approximately 700 micra mol mol-1. No unambiguous effects of the methanol applications were detected in net photosynthesis measurements made on foliage in either of the two CO2 treatments. The 75% increase in CO2, however, raised the upper-limiting leaf temperature for positive net photosynthesis by approximately 7 C, wthich resulted in a 75% enhancement in net photosynthesis at a leaf temperature of 31 C, a 100% enhancement at a leaf temperature of 35 C, and a 200% enhancement at 42 C. |
