However their value are much greater than Revised 30 01 2023 that of the Orchid. In the genus Dendrobium there are many species that give Published 30 01 2023 beautiful and fragrant flowers. One of these species Hoang Thao Tram Dendrobium parishii Rchb. f. Orchidaceae is a species with a high attractive aroma which were confirmed by scientific studies on extracting the KEYWORDS essential oil. Currently natural species D. parishii in the forest is being Dendrobium parishii seriously degraded due to overexploitation and uncontrolled exploitation while the quantity of industrially produced seed has not been effectively In vitro exploited. The tissue of breeding to provide a source of plants for ornamental Protocorm collection and essential oil extraction should be concerned. In this study Planting material some conditions for in vitro culture and care of D. parishii seedlings at nursery stage were investigated. The study results showed that the suitable Plant nursery clean seed protocorm generation medium of D. parishii which was MS supplemented with BAP or kinetin mg l the supplements included green banana potato and carrot puree each. 40 g l. The in vitro seedlings at the nursery stage are cared for in accordance with the following conditions i suitable in vitro seedling medium is coir ii planting density is 1 tree pot iii Initial watering with tap water and using 60 sun net to cover the plants.
