This study was carried out to investigate the effects of NH4+, Ca++ and Mg++ ions which could have influences on the protocorm proliferation and organogenesis through protocorm culture of Cymbidium elcapitan 'Conquestador' obtained by shoot tip culture. The relations between inorganic nutrient in the medium and those in the plant tissue were also studied. Best shoot formation and growth occurred in a medium with 4 mM of NH4-N while good root formation and growth were obtained from no NH4-N treatment. As the NH4-N level in the medium increased, potassium content in the tissue decreased, whereas P and Mg contents increased slightly
