摘要
OBJECTIVE:To 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.
METHOD:The 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.
RESULT:The 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.
CONCLUSION:The hybrid integrates superiority of parents on growth and accumulation of medicinal components opens vast vistas for development and utilization.
