模拟酸雨对乳源木莲幼苗生长的影响

A Study on the Effects of Simulated Acid Rain on Growth of the Seedlings of Manglietia Yuyuanensis

应用溶液喷洒法,研究不同pH值模拟酸雨对乳源木莲在叶片健康、株高生长、生物位积累、叶绿素含量及叶汁液pH值的影响,并从正生物效应和负生物效应两方面探讨了酸雨对苗木生长的影响。研究结果表明,该植物在华南地区城市园林绿化中具有较大的应用前景。

The effects of simulated acid rain with the pH values ranging from 2.0 to 6.0 on the seedlings of Manglietia yuyuanensis Law were studied. The foliage damage, height growth, biomass, chlorophyll content and pH variation of the leaf sap of the seedlings growing in different pH conditions were monitored. Its growth responses to acid rain were discussed on both positive and negative effects. The results showed that the plant might have a great potential to be applied in urban amenity planting.
