Abstract
MEASUREMENTS of net assimilation rate by growth analysis techniques have shown significant differences between North European and Mediterranean populations of Dactylis glomerata in controlled environments at low and high temperatures1, and between a similar range of populations of D. glomerata, Festuca arundinacea and Lolium perenne in the winter, spring and autumn at Aberystwyth2. Greater net assimilation rates were found for the North European populations in all these conditions. Variations in the rates of photosynthesis and respiration have also been reported for climatic races of Solidago virgaurea3, Oxyria digyna4 and Mimulus cardinalis5.
