“…In L. Acclimation for temperature at which PN is optimum has been shown in many species grown under controlled environmental conditions (Mooney and West 1964, Strain and Chase 1966, Strain 1969, Billings et al 1971, Chabot and Billings 1972. In the field, Stalfelt (1937), Kusomoto (1957), DePuit andCaldwell (1973), and Lange et al (1974) (Saweda and Miyachi 1974). In view of microhabitat variability in a harvested maize field, some differences in degree of temperature compensation for photosynthesis probably reflect differences in acclimation in the field caused by differential protection of their rosettes.…”

“…Slight losses in total water content may significantly lower the resistance t o gaseous diffusion offered by the wet cell ~valls. Stalfelt (1927Stalfelt ( , 1938 attributed a decline in the gas exchange of water-saturated mosses and lichens to iinpaired gaseous diffusion. Sinlilar conclusions were reached by Jumelle (1S92), Fraymouth (192S), ancl Ensgraber (1954).…”

A simple rllethod of subjecting wheat seecllings to progressive water stress and of measuring the respiration rates is described. Slight water tleficits increased CO? output by about 20y0, and more severe water stress decreased it by about SOYo. Water stress caused signilicnrit changes in the coilcentratioils of malate and citrate and of an unknown organic acid. Water stress stril;iilgly decreased the level of malate in the roots and increased it in the shoots. It is suggested that the clecrcase in respiratioil caused by water stress cannot be attributed to an increased rate of dark iixatiou of carbon dioxide.

“…The diffusion coefficient of CO 2 in water is about 10,000 times less than in air, so superincumbent water increases resistance to CO 2 uptake at higher (total) water contents. Depressed NP at higher WC has been commonly found for lichens (e.g., Kershaw 1972;Lange et al 1994) but it is equally true for bryophytes (Stålfelt 1938;Dilks and Proctor 1979;Alpert and Oechel 1987), except that bryophytes commonly have adaptations which minimize the conflict between water storage and gas exchange (Proctor 1979a(Proctor , 2002(Proctor , 2009; Fig. 18.4).…”

Irradiances in the original measurements were expressed in kilolux and have been roughly converted to equivalent quantum flux units.…”
