Abstract Oncidium Golden Anniversary orchid is a hybrid variety from Oncidium spacelatum and Oncidesa sarcatum orchid.

However, this orchid flower is having difficulty when it requires strong, mature pseudobulbs to bloom. Pseudobulbs store the nutrients absorbed by the roots. Therefore, this research focuses on the roots’ growth in in vitro culture until the acclimatization stage. In this resear
