Fig. 3 Relationships between the intact root respiration rate (Rr) of
C. obtusa and Q. crispula and the transpiration rate (E) at 1 h
before the measurement of root respiration in the field measurement.
Different symbols denote different root samples (n = 4). The
E values are indicated as the mean ± SE of five leaves. In C.
obtusa, the relationships of two samples were fitted by logarithmic
function. The regression equations are as follows: filled circles
