Abstract: Seasonal changes in shoot development and in organ formation activities of shoot apex explants in vegetative phase were examined throughout the year in Cymbidium. Protocorm-like bodies (PLB) formation of shoot apices excised with two leaf primordia was morphologically observed under light microscope. The activities of shoot elongation, leaf differentiation, and PLB formation changed parallel with each other throughout the year. The activities remarkably increased in April and reached maxima in June. The activities decreased slightly in August and thereafter remained unchanged until the next March. Then, they decreased remarkably in August and disappeared in September. Definitely from the axillary region and adventitiously from the basal region, PLBs were formed. In the former case they were called “definite PLBs” and in the latter case “adventitious PLBs”.
