The sprout of P. ternata was occurred in the middle or the end of April in Kyoto district. The development of the top following the sprout brings not only thickening of corms, but also growing of bulblets on the petiole. Therefore, a sprout of corms left a source for propagation of this plant behind. The purpose of this paper was to report on some aspects of sprouting of corms and bulblets of P. ternata. 1) The corms and bulblets began to sprout, if they were under low temperature for 30〜50 days. However, they were not able to sprout when they were kept in the constant temperatures of 15℃. So they were broken their dormancy under the lower temperature of winter season and they began to sprout from the middle to the end of April. 2) The corms whose tops and roots were removed from June to September were planted again. Within few days after the treatment they began to resprout. 3) The bulblets sprouted more than 80% in June to August, but their sprouting percentage suddenly decreased in September. The sprouting percentage of the small bulblets was not so high as the large ones. 4) The apical dominance was not recognized in every bud of corms.
