In the present investigation, the difference in sensitivity to ω-methylpantothenic acid among various species of plants was studied in connection with their patterns of respiratory function, and the following results were obtained.<br>1. The levels of oxygen consumption of rice plant and Japanese millet (belonging to Panicoideae subfamily) were lower as compared with those of barley (belonging to Festucoideae subfamily) and cucumber (belonging to dicotyledonous plant) in the buffer solution.<br>2. The addition of ω-methylpantothenic acid brought about the increase of oxygen consumption of all the tested seedlings temporally in the early period such as first 24 hours with treatment of ω-methylpantothenic acid. After 48 hours, however, the consumption began to decrease in two species of barley (Festucoideae subfamily) and cucumber (dicotyledonous plant), which were recognized to be inhibited by this antagonist at this concentration. On the contrary, the former two species showed continuously a resistance to this inhibitory action.<br>3. The results of 1 and 2 show that the stronger inhibitory action of ω-methylpantothenic acid appears with those species, barley and cucumber, which had high level of oxygen consumption in the germination.<br>4. From a consideration of present data and Taylor's suggestion that the ability to germinate and grow in very low oxygen concentration depends upon the possession of high functional fermentation system, it seems reasonable to assume that ω-methylpantothenic acid inhibits the oxidative respiration rather than the fermentation on the germination process.<br>5. The mechanism of the action of ω-methylpantothenic acid upon the germination of higher plant was discussed in connection with their patterns of respiratory function.
