The stomatal function of leaves of pear, Japanese pear, apple, peach and grape was estimated using the relative transpiration rate and the stomatal resistance. The results obtained were as follows: 1. The dullness of stomatal function proceeded with leaf age in pears, apples and grapes. Especially, that of Bartlett pear was observed very early in the late of June, and proceeded extremely after the middle of July. That of Fuji apple and Concord grape was observed after the early of August, however, the dullness was more slight as compared with Bartlett pear. On the other hand, The stomatal function of Kanto No. 5 peach still kept the sharpness to the late of August. 2. The closing function of stomata of intact leaves under arid conditions was the highest in Kanto No. 5 peach and declined in the order of Fuji apple, Concord grape, KOsui pear, Shinsui pear and Bartlett pear. That of the apical leaves of a shoot was higher than that of basals in the all cultivars. 3. Among the stomatal function of the cultivars of pear and Japanese pear, the dullness of Bartlett was prominent throughout the season. And it was recognized that the duller the stomatal function, the higher the sensitivity to the leaf burn was.
