TEMPERATURE ON PHOTOSYNTHESIS AND TRANSPIRATION IN POPULATIONS OF SESLERIA CAERULEA (L) ARD.

Authors


Summary

Samples of populations of Sesleria caerulea (L) Ard. were grown under controlled conditions. Rates of photosynthesis and transpiration were measured in an open gas system over the leaf temperature range, 7.5°–30°C. Populations differed significantly in light-saturated photosynthetic rates and these differences resided in the stomatal resistance to CO2 assimilation.
