Abstract

Zea mays L., Saccharum officinarum L., the sorghums, and several other grass species have maximum rates of photosynthesis near 60 mg CO2 dm-2 hr-1 and are tolerant of the herbicide, 2-chloro-4-ethylamino-6-isopropylaminos-s-triazine (atrazine). In contrast, the small grains and numerous other grasses have maximum rates of photosynthesis of about 20 mg CO2 dm-2 hr-1 and are susceptible to atrazine. The correlation between these traits suggested that atrazine tolerance might be a useful selection criterion to detect efficient photosynthesis. Using this hypothesis, Digitaria and Setaria species which are tolerant of atrazine, were found to have efficient photosynthesis.
