Abstract: Introduction: Dendrobium orchid is one of the ornamental plants that has high economic value.Each variety has its own characteristics and forms.Climatic and genetic factors are very influential on plant growth and physiological processes that occur in plants.Efficiency in the use of water is important to increase plant growth.This experiment aims to determine the effect of Dendrobium orchid varieties and the humidity of the growing media on growth, the amount of photosynthesis and transpiration.Methods: The experiment was carried out in Sidomulyo village, Candimulyo Magelang, starting from June to October 2021.The experiment was carried out in a plastic house.The experimental method used was a randomized block design with three replications.The factors tested were two levels of growing media humidity (35-70%; 40-80%) and five genotypes of dendrobium orchids ((ERG, IRB, GM, BS and GDA).The agronomic characters observed were plant height (cm), number of leaves, and stem diameter.Photosynthesis (µmol/m2/s) and transpiration (mmol/m2/s) were measured using a photosynthesis measuring instrument LI-6400.Results:The experimental results showed: 1.There were differences in the growth of five varieties of dendrobium orchids, 2. Varieties of dendrobium G3, G4 and G5 PAR's were higher at 40-80% humidity media, on the other hand G1 and G2 were highest at 35-70% humidity media, 3. The amount of transpiration of dendrobium was higher at 40-80% growing media humidity, except for G2.Conclusion: The results showed that there was no effect of differences in media humidity on the growth and transpiration of the five dendrobium orchid genotypes.Genotypes affect the vegetative growth of dendrobium orchids.Optimal media humidity for the growth of dendrobium orchids is 35-70% humidity.
