[Effects of sampling time on polysaccharides of Dendrobium catenatum under temperature-controlled condition].
In order to reveal the accumulation trend of polysaccharides in Dendrobium catenatum and determine the effect of sampling time on polysaccharides, D. Catenatum D21 clone was harvested from January to December after culturing for 2 to 5 months in the growth chamber with constant temperature. ⋯ The results showed that the content of polysaccharide and its key component mannose was positively correlated with the culture time, but the contents of polysaccharides in all kinds of culture peaked from 5 to 6 months, which were consistent with the trend of field planting. The results suggested that the trend of polysaccharide accumulation in the plant could be related to the life rhythm of the sensory seasons of D. catenatum, which was significantly affected by the harvesting season, even under the constant condition of the culture chamber.
