RESUMO

<p><b>OBJECTIVE</b>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.</p><p><b>METHOD</b>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.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>The hybrid integrates superiority of parents on growth and accumulation of medicinal components opens vast vistas for development and utilization.</p>
