Abstract: | The root activity, the chlorophyll content, the proline content and the soluble sugar content of Rhododendron dauricum and Rhododendron mucronujatum after raise 20 days were determined by different pH value. The result showed that have significant impat of pH value on Rhododendron dauricum and Rhododendron mucronujatum, and when oH was 5.5 the seedlings growth best. |
