摘要
在不同pH的栽培基质上,对培养20天后的兴安杜鹃、迎红杜鹃苗木的根系活力、叶绿素含量、脯氨酸含量和可溶性糖含量进行了测量,其结果表明,pH水平对兴安杜鹃、迎红杜鹃苗木各生理指标均有显著影响,当pH值为5.5时,苗木的生长状态最佳。
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.
