The trial for the study of the transition regions of Hunan and other commonly used six warm-season turfgrass through the district Introduced trial on six turfgrass growth period , external morphology, flowering and fruiting period biological traits such as research and combination lawn quality evaluation system for six lawn lawn comprehensive evaluation of traits , its main findings are as follows : phenophase six lawn grass brown in early December , in mid-March , the second year of turning green . Six tested grasses , of seashore paspalum paradise grass 419 strong. Observations of turfgrass during the trial period , the green period of the same. Found after three years of observation , common bermudagrass green period of 282 days , XN -1 Zoysia 280 days , Lanyin III 278 days , paradise grass 419 to 275 days , 269 days seashore paspalum , centipedegrass 262 days . Turfgrass external morphology observation , grasses there are big differences in the external morphology , six grass XN-1 Zoysia the shortest internodes , average 0.56cm, the Centipedegrass section between the longest average 3.18cm, the internode length range between 0.56cm-3.18cm . Leaf length , paradise grass 419 average leaf length 3.13cm, common bermudagrass average leaf length 3.45cm . Zoysia leaf length 3.78cm XN-1 was significantly shorter than the 3 Lanyin 5.32cm . Various types of lawn texture as follows : gt paradise grass 419 ; the XN- Zoysia gt ; to Centipede Grass gt ; the seashore paspalum gt; Lanyin III gt ; common bermudagrass . Cold resistance , after the determination of the grass field observations and laboratory physiological and biochemical indicators , combined with the analysis of conductivity , proline , soluble sugar , malondialdehyde come to different changes in the body content of various grasses , grass species of cold hardiness differences : common bermudagrass gt ; the XN- Zoysia gt ; to Centipede grass gt ; gt paradise grass 419 ; 3 Lanyin , gt ; seashore paspalum . Tested six grass are turfgrass excellent performance in Changsha , Hunan and other similar habitats lawn suitable for the growth in the transition region . Comprehensive evaluation of six kinds of lawn grass , XN -1 Zoysia highest score Centipedegrass lowest , middle order paradise grass 419, common bermudagrass 3 Lanyin , seashore paspalum .
