Research of Cold Resistance on Four Kinds of Turf Grass
Using Bermudagrass,Festuca elata,Poa annua L. and annual Poa pratensis L. as materials,conductivity value in different time and different low temperature stress for the leaves were measured by electrical conductivity which helped to evaluate the quality of lawn. Result showed that the relative electric conductivity of the four kinds of turf grass all increased at first and then decreased with the decreasing of temperature.While the treating time was prolonged,there were little change.Strong-to-weak sequence of cold resistance on the four kinds of turf grass was Festuca elata,Poa annua L.,Bermudagrass,Poa pratensis L..
