Abstract
This study investigates the effects of various growing substrates and fertilizer treatments on the acclimatization and growth of heat-tolerant Cymbidium orchid (Cymbidium Golden Vanguard). The results indicate that substrate quality is a critical factor influencing the survival and growth of in vitro plantlets during acclimatization. Specifically, treated coconut husk pieces and treated coconut coir demonstrated the highest survival rates at 97% and 95%, respectively. In contrast, untreated substrates exhibited lower survival rates, highlighting the effects of residual toxic compounds. The application of NPK 30:10:10 fertilizer significantly enhanced both plant height and leaf number compared to other treatments, demonstrating its effectiveness in promoting vigorous development of orchid plants. The findings emphasize the need for optimal substrate selection and fertilization strategies to enhance the growth of heat-tolerant Cymbidium orchid in greenhouse conditions.
