R. Leuning, SCALING TO A COMMON TEMPERATURE IMPROVES THE CORRELATION BETWEEN THE PHOTOSYNTHESIS PARAMETERS J(MAX) AND V-CMAX, Journal of Experimental Botany, 48(307), 1997, pp. 345-347
A strong correlation between the photosynthetic parameters J(max) and
V-cmax was found by Wullschleger (1993) in a survey of 109 plant speci
es. Measurements were made at various leaf temperatures, but the tempe
rature dependence of J(max) and V-cmax differ. Once values for J(max)
and V-cmax in Wullschleger's analysis were adjusted to a common temper
ature, using an equation for the temperature dependence of these param
eters, the slope of the linear regression for J(max) versus V-cmax for
ced through the origin increased from 1.97 to 2.68, and r(2) increased
from 0.79 to 0.87.
