Abstract
Respiratory rates of shoots of mulberry were markedly different from sample to sample under the same temperature when the respiratory rate were expressed on a dry weight as well as on a volume basis. Wheareas, if they expressed on a surface area basis, respiratory rates approached to a definite value for each temperature. Therefore, it is advisable to express the respiratory rate on a surface area basis.<br>The relation between temperatures (T) and respiratory rates of annual shoots (Ra), for 1002cm2 of surface area, was expressed by the following empirical equation I:<br>Ra=0.4705e0.0718T……Equation I<br>The calculated value of Q10 was 2.05 by this equation.<br>The relation between temperatures (T) and relative respiratory rates (Rr), expressed as the percentage of the respiratory rate measured at 20.0±1.1°C per sample, was expressed as follows:<br>Rr=19.9898e0.0733T……Equation II<br>Using this equation, respiratory rate measured at a definite temperature could be altered to the expected rate at the other arbitrary temperature.<br>The respiratory rate of shoots at a specific temperature can be obtained from the following quation.<br>R(t2)R(t1)·Rr(t2)/Rr(t1)……Equation III<br>Where R(t1) was the value of respiratory rate measured at t1°C and R(t2) was the expected value at t2°C. The solution of the equation II was expressed as Rr(t1) and Rr(t2), when the T of the equation II was substituted for t1 in the former and t2 in the latter.
