''Agrostis'' (bent or bentgrass) is a large and very nearly cosmopolitan genus of plants in the grass family, found in nearly all the countries in the world.〔(Linnaeus, Carl von. 1753.

This is a desirable grass for golf course tees, fairways and greens. Bentgrass is used in turf applications for its numerous advantages: it can be mowed to a very short length without damage, it can handle a great amount of foot traffic, it has a shallow root system that is thick and dense allowing it to be seeded and grow rather easily, and it has a pleasing, deep green appearance. The name "bent" refers to the shallow roots, which bend just below the surface of the soil to propagate laterally. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「agrostis」の詳細全文を読む スポンサード リンク
