Net CO2 assimilation (A) was analysed in situ in 12 pairs of altitudinally separated, herbaceous plant species in the Austrian Alps at 600 and 2600m. Both groups of species show a similar average response to light, saturating at quantum flux densities (400-700mm) (QFD) of more than 1200 VLmol m-2 sol. Temperature optimum of QFD-saturated A differs little (3K) and corresponds to the median of air temperature at leaf level for hours with rate-saturating light conditions and not to mean air… CONTINUE READING
