Lawn quality change of different grass species and influence factors analysis in Beijing area

Lawn quality of 112 cultivars including five cool-season species and one warm-season species turfgrasses were evaluated and its influence factors were analyzed in Beijing area. The results showed that Lolium perenne and Agrostis had the fastest establishing speed, and Poa pratensis the slowest among five cool-season species. Warm-season common Cynodon dactylon showed the slowest establishing speed in six test species. Lawn quality of warm-season and cool-season species had obvious seasonal difference. Warm-season turfgrasses had the highest quality in the hottest July and August, however, cool-season turfgrasses behaved well at spring and autumn. Seasonal change and species are two important factors affecting lawn quality, but variance of different cultivars was small, equivalent to that of different replications.
