Abstract:
OBJECTIVETo compare the hybrid between species of Dendrobium huoshanense and its parents on growing, physiologic indexes and content of medicinal components, and provide theoretical basis for species quality improvement.
METHODThe chlorophyll content, the photosynthesis rate, the polysaccharides content and the alkaloids content were measured by anhydrous ethanol method, Cl-310 photosynthesis determination system, colorimetry of concentrated sulphuric acid-phenol and acid dyes colorimetry respectively.
RESULTThe growth of hybrid was close to D. moniliforme, and apparently higher than D. huoshanense. The chlorophyll content and the photosynthesis rate of one-year-hybrid were markedly higher than its parents. The content of polysaccharides and alkaloids in two-year-stem and three-year-stem of hybrid were close to that of D. huoshanense.
CONCLUSIONThe hybrid integrates superiority of parents on growth and accumulation of medicinal components opens vast vistas for development and utilization.
