1) The distribution and the role of hormones in the long term dormant axillary buds of Nandina domestica were investigated by the methods of MOLISCH's warm-bath and WENT's Avena-test and also by the application of paper-chromatography to the separation and identification of hormone substances. 2) Until five years, the germination-and growthpower of the dormant axillary buds of Nandina, gradually reduce in proportion with the elapse of years, but after five years, their powers of germination and growth will be remarkably reduced. 3) All dormant axillary buds of Nandina contain the growth promoting substances, the younger bud containing more than the older one. 4) It may be concluded from the Avena-test, and by the application of paper-chromatography to the separation of hormone substances, that the growth promoting substances contained in the dormant bud of Nandina that localize in the zones of Rf 0.8-0.9,0.4-0.5 and 0.0-0.1 of the paper-chromatgram, and the growth inhibiting substances are the substances localizing in the zones of Rf 0.5-0.7 and 0.1-0.2. Among these substances the chief growth promoting substances are the substances that localize in the zones of Rf 0.8-0.9 and 0.4-0.5,and the growth inhibiting substances are the substances localizing in the zone of Rf 0.5-0.7.
