Adaptation research of Kentucky bluegrass in Chinese cool-humid zone(Shenyang)

In order to test the adaptation of new varieties of Kentucky bluegrass ( Poa pratensis L.) in north China, the adaptation of Kentucky bluegrass in Shenyang (cool humid zone) was studied. Its growth performance, biology characteristics, turf formation and resistance to stress were observed. Its density, texture, resistance to heat and disease, greenness, green duration and overall performance were evaluated by grading method, respectively. The result shows that Ky. bluegrass can adapt to the soil and climate in Shenyang. Due to its excellent performance, Ky. bluegrass has become the primary turfgrass in Shenyang area.
