摘　　要：以白三叶(White clover,Trifoluum L.)、拂浪(Fine lawn,Festuca Schreb)、纽布鲁(Kentucky bluegrassPoa L.)和普特(Putter Agrostis L.)作为试材,采用水培法研究了不同pH值对其叶绿素含量等生理指标的影响。结果表明,在这4个草种中,纽布鲁具有较强的抗碱性。In this study, four kinds of grasses, Write clover Trifoluum L., Fine lawn Festuca Schreb, Kentucky bluegrass Poa L.and Putter Agrostis L.were cultured in different pH solution. The effects of pH solution (6.5, 7.0, 7.5, 8.0) on the physiological level such as chlorophyll content, cell membrane permeability were analyzed. The results showed that the tolerance to alkaline was higher in Kentuchy bluegrass than the other three.
