Acidic growth substances in the leaves of a clone of six-year-old Chamaecyparis obtusa were extracted every month during one annual growth cycle. Auxins and inhibitors were separated using paper chromatography and assayed by Avena coleoptile straight-growth test. Auxins were comparatively abundant in the growing season (April-October) and scarce in the resting period. Inhibitors were the least in the period when active extension growth occurred and rather steady in a lower level, with little variation in the resting period. The major auxin obtained in April was tentatively regarded as IAA.
