• The CN-resistant alternative oxidase pathway was examined in relation to the formation of callus and adventitious roots of Jerusalem artichoke tuber tissues. During the early stage of incubation at 28℃, respiration was significantly activated and the O_2-uptake rate via the Cyt pathway increased 2.5-2.6 times by the second day of culture regardless of the presence of 2,4-D. However, further increases and preservation of high levels of Cyt pathway activities were observed only in the callus-forming tissues. The capacity of the alternative pathway also increased, but the actually operating fraction was very small (0-4% of total respiration). On the other hand, during the later stages of culture in which adventitious roots emerged from the callus, activation of the alternative pathway was observed. These results suggested that the alternative pathway was not involved in callus growth but was related to root formation in callus tissues of Jerusalem artichoke tubers.
