| Abstract: | Objective To determine the suitable support materials for growing Dendrobium officinal,substrate cultivation poles,concrete poles and bamboo strips and trunks of four different trees were used as experimental materials. Methods Polysaccharide content was determined by a phenol-sulfuric acid method.Results It showed polysaccharide content in the Dendrobium plants attached on the trunks of Santalum album,Dalbergia odorifera and Acacia mangium trunks all exceeded 5.0%,followed by that grwon in flower pots at 4.16%.The Dendrobium plants attached to concrete poles and bamboo strips had equal polysaccharide content of 3.10% while the lowest content of 2.87% was obtained for the Dendrobium plants fixed to Dimocarpus longan.Conclusion These results demonstrated that using the trunks of S.album,D.odorifera and A.mangium as epiphytic support materials could greatly increase the polysaccharide content in this Dendrobium officinale species. |
