Nobile-type dendrobium includes the hybrids selected from the crossing of Dendrobium nobile. The typical method for vegetative propagation of Dendrobium is using lateral buds as propagation materials. Dendrobium is a kind of sympodial orchids that produces 1-2 buds per year from the back shoots. When the new shoots reach a limited height, flag leaves at the top of the shoots develop and the shoots stop elongation. Then the shoots begin enrich and turn into pseudobulbs. The mature pselldobulbs are ready to bloom after low temperature treatment. Japan is one of the important countries that put the efforts on research of nobile-type dendrobium. This review focused on the description of physiological knowledge about nobile-type dendrobium in Japan, especially on the physiology of bud formation and blooming. Hopefully the information can offer some idea for researchers and growers in Taiwan.
