Salt (NaCI + buffer) and alkaline soluble protein contents and GA-like activity in leaf and bark tissues of non-bearing and bearing shoots of 'Kawano Natsudaidai' (<I>Citrus natsudaidai</I> Hayata) were investigated in relation to flower bud formation.<BR>Salt-soluble protein content of leaf and bark tissues of non-bearing shoots was always higher than that of bearing shoots. There was no significant difference in alkaline-soluble protein content of leaf and bark tissues of bearing and non-bearing shoots. When salt-soluble protein of leaf and bark tissues was separated by polyacrylamide gel electrophoresis, the number of bands and intensity of staining in both tissues of non-bearing shoots were greater than were those of bearing shoots. High molecular weight bands of non-bearing shoots stained more intensely than did those from bearing shoots.<BR>There were no significant differences in GA-like activities in bark tissues of bearing and non-bearing shoots in September. GA-like activities in both kind of shoots decreased slightly during October and November. However, GA-like activity of bearing shoots decreased less than did that of non-bearing shoots.
