| 摘 要： | 通过观测直立枝和匍匐枝的叶片长度和宽度、草层高度、节间直径和节间长度等7项指标,比较分析了裸露地、荫蔽地、旱地和盐碱地4种生境的狗牙根Cynodon dactylon(Linnaeus)Persoon]种质的形态差异。结果表明:就狗牙根的坪用价值而言,依次是旱地生长的狗牙根>裸露地生长的狗牙根>盐碱地生长的狗牙根>荫蔽地生长的狗牙根。

| Abstract: | The morphological characters of Cynodon dactylon were estimated through 7 indices including leaf length of upright stem,leaf width of upright stem,leaf length of stolon,leaf width of stolon,turg height,internode diameter and internode length in 4 different habitats(sun ground,shade ground,xeric ground,and saline and alkaline land).The results indicated that the turf quality of wide C.dactylon in different habitats was ranked as follows: xeric ground>sun ground>saline and alkaline land>shade ground. |
