Abstract

Drought is a major limiting factor in turfgrass management. Turfgrass responses to water deficit depend on the amount and the rate of water loss as well as the duration of the stress condition. This review paper was designed to understand responses such as photosynthesis, canopy spectral reflectance, plant cell, root, hormone and protein alteration when turfgrass got drought stress. Furthermore, mechanisms to recover from drought conditions were reviewed in detail. However, there are still many questions regarding plant adaptation to water deficit. It is not clear that the mechanism by which plants detect water deficit and transfer that signal into adaptive responses. Turfgrass research should focus on the best management practices such as how to enhance the ability of self-defense mechanism through understanding plant responses by environmental stress.

잔디가 건조 스트레스를 받은 상태에서 잔디의 생리학적 메커니즘과 건조 상태에서 식물이 회복하는 생리학적 메커니즘을 보다 깊이 이해하고자 한다. 증산작용과 Stomatal Conductance의 상호 관계로 인한 광합성량의 변화, 식물 세포 내부의 변화, 삼투압 조절능력의 변화, 호르몬의 변화, 단백질 변성 등의 생리학적 반응들을 이해하고 건조 스트레스 상태에서 회복하는데 세포내부의 적응 과정, 뿌리의 반응과 같은 생리학적인 측면에 대해 이해하고 건조 스트레스 상태에서 엽록소가 흡수하고 반사하는 Spectral Reflectance의 변화를 이해하고자 한다. 하지만 건조스트레스로 인한 식물의 생리학적 메커니즘에는 아직 많은 의문점을 가지고 있으며 향 후 외부환경 스트레스에 의한 식물의 Self-defense 메커니즘을 더욱 깊게 이해하여 보다 수준 높은 관리기법들을 연구하는데 초점을 맞추어야 할 것이다.
