By potted planting experiments, Loropetalum chinense var. rubrum, Rhododendron simsii Planch and Rhododendron indicum seedlings, planted in pots, were treated with simulated acid rain of three different pH values(3.0, 4.0, 5.0)so as to study its effects on their mineral element contents. The results show that the mineral element contents in leaves of the three shrubs varied to a certain extent. They showed difference in reaction to acid rain. The contents of Potassium (K), Magnesium (Mg), Manganese (Mn), Nickel (Ni), Sulphur (S) and...
