Quality was generally greater in LPS and CM. Turf quality followed the sequence LPS ≥ CM>NM2>NM1 ≥ LPY (Table 4).
Generally, summer was superior to other seasons .Season effect on quality followed the sequence summer>spring>autumn>winter (Table 4). Results indicated that LPS,CM and NM2 had a higher visual quality in summer .All turf grass types had lowest turf quality in winter,and the regularity of quality in winter was LPS ≥ CM>
NM1> NM2 ≥ LPY (Fig. 1E).
