본 실험은 ISTA 변온 및 자연실온 환경에서 퍼레니얼 라이그래스 신품종의 종자 발아력, 초기발아속도 및 발아피크기간 등의 특성을 연구 비교해서 실무적으로 한지형 잔디의 설계, 시공 및 관리에 활용하고자 시작하였다. 실험 I은 ISTA 변온(8시간: 광조건,
Research was initiated to investigate early germination and establishment characteristics of perennial ryegrass (PR, Lolium perenne L.). An alternative condition was applied in Experiment I with 8-hr light at

퍼레니얼 라이그래스의 원산지는? | )가 있다. 이중 퍼레니얼 라이그래스는 원산지가 아시아와 북아프리카의 온대 기후대 지역으로 주형생장을 하는 영년생 잔디로 잉글리쉬 라이그래스(English ryegrass) 라고도 한다(Beard and Beard, 2005; Thorogood, 2003). 퍼레니얼 라이그래스는 조성속도가 빠른 특성 때문에 한지형 잔디의 혼파 시 잔디밭의 일시적인 피복목적, 난지형 잔디의 동절기 녹화 및 법사면 토양침식방지 목적 등으로 많이 이용되고 있다. | |
국내에서 한지형 잔디로 조성된 골프장 티, 페어웨이, 러프 및 법사면에 이용되고 있는 대표적인 초종에는 무엇이 있는가? | 국내에서 한지형 잔디로 조성된 골프장 티, 페어웨이, 러프 및 법사면에 이용되고 있는 대표적인 초종에는 켄터키 블루그래스(Poa pratensis L.), 퍼레니얼 라이그래스 및 톨 훼스큐(Festuca arundinacea Schreb.)가 있다. 이중 퍼레니얼 라이그래스는 원산지가 아시아와 북아프리카의 온대 기후대 지역으로 주형생장을 하는 영년생 잔디로 잉글리쉬 라이그래스(English ryegrass) 라고도 한다(Beard and Beard, 2005; Thorogood, 2003). | |
퍼레니얼 라이그래스는 기후대에 따라 어떤 생활사를 나타내는가? | 퍼레니얼 라이그래스는 온화한 해양성 기후대에 적합한 초종으로 온도변화가 심한 지역에서는 적합하지 않다. 예를 들어 온화한 기후대인 독일 북서부 지역 또는 영국에서는 영년생으로 유지되지만, 동절기 온도가 상당히 낮은 미국 동북부 뉴잉글랜드 지역에서는 생활사가 1-3년 정도되기 때문에 단기 영년생(short-lived perennial)으로 지속된다(Hanson et al., 1969). |
