Photosynthesis occurred even at \degr{-3} Gannutz (1970) said that the antarctic spp (i.e. DA and CQuitensis) are damaged by sub-zero temperatures fresh weight: surface area relationship for all photosynthetic tissue was 77+/- 22 cm^2g^-1 (sort of like SLA?) (includes leaf sheath material and old leaves) they can acclimate to wind P. cookii is dependent on temperature, but only to a degree. Light is more important. Temperature optima. Optimum reached at 12 degrees, and at 25 degrees starts to go down. High productivity. Net CO2 fixation increased to 12oC, then remained stable to 19oC, then ? While dark respiration increased exponentially with temperature. Respiraiton into CO2 free air in the light was also temperature sensitive, but was substantially lower than dark respiration.co2 compensation concentration predicted to be 100 ppm Adaxial leaf surface very irregular, epidermal cells oftenoverhang/occlude the deep stomatal pits. the chlorophyllous mesophyll may not receive much of the incident light.}, interhash = {f82fc1e3efc20b05c5120272cb87363a}, intrahash = {3f70a4e051c7a4c33ee3a180eb94db27}, journal = {New Phytologist}, keywords = {bibtex-import, citeulikeExport gas\_exchange, grass, honours, papercopy, temperature}, number = 4, pages = {533--543}, posted-at = {2007-07-31 06:06:39}, priority = {2}, timestamp = {2019-03-31T01:16:26.000+0100}, title = {{Photosynthesis and respiration in the sub-antarctic tussock grass @Poa cookii}}, volume = 95, year = 1983 }
