Abstract
Effects of three temperature regimes (16/5, 24/11, and 32/16 degrees C day/night temperatures) and two moisture levels on growth, interferen ce and photosynthesis response in Bromus tectorum and Taeniatherum asp erum were investigated in a growth chamber study. Plants were grown se parately and in intra- and interspecific pairs. Optimum temperature fo r growth of both species was the moderate regime (24/11 degrees C). At this regime T. asperum yield was higher than that of B. tectorum. Yie ld of B. tectorum was less affected by temperature extremes and was si gnificantly higher than that of T. asperum.
