Increasing concerns over green farming technology, plant growth promoting rhizobacterium (PGRP) having growth promoting as well as plant disease suppressing properties was recently preferred to use for biological control of plant pathogens infecting plant. We measured the influence of the selected m...

토양생태계의 건전성 평가하는 방법은 무엇인가? | 토양미생물군집의 생태를 분석하기 위한 방법 중 토양효소 활성도 측정은 토양비옥도를 반영하여 토양질의 중요한 생물지표가 되는데(Paul과 Clark, 1989; Anderson, 1991; Kirschbaum, 1995; Nobili 등, 2006; Hu와 Cao, 2007; Koch 등, 2007), 주변 환경 여건에 따라 토양미생물의 상대적 활력도가 달라지므로 특정 효소활성을 측정함으로써 토양미생물의 상대적 활성을 측정하고 이를 기준으로 토양생태계의 건전성을 평가할 수 있다(Speir 등, 1999; Chew 등, 2001; Langer와 Günther,2001). 그 중 dehydrogenase는 토양호흡의 지수로 사용되고(Garcia 와 Hernandez, 1997), urease는 토양 내 미생물들이 이용할 수 있는 질소원을 공급하는 역할을 한다(Garcia-Gil 등, 2000). | |
plant growth promoting rhizobacterium(PGPR) 균주란? | 최근에는 식물병원균에 대한 길항능과 식물생장촉진능을 동시에 가지는 plant growth promoting rhizobacterium(PGPR) 균주에 대한 연구가 활발히 진행되고 있다(Jung 등, 2006; 2007). PGPR은 식물뿌리주변에 서식하는 근권미생물로서 식물병원성 진균의 세포벽을 분해하는 용균작용(Lim과 Kim, 1995; Han 등, 1999; Yun 등, 2001), Bacillus sp., Pseudomonas sp. | |
plant growth promoting rhizobacterium(PGPR) 균주의 기능은 무엇인가? | 최근에는 식물병원균에 대한 길항능과 식물생장촉진능을 동시에 가지는 plant growth promoting rhizobacterium(PGPR) 균주에 대한 연구가 활발히 진행되고 있다(Jung 등, 2006; 2007). PGPR은 식물뿌리주변에 서식하는 근권미생물로서 식물병원성 진균의 세포벽을 분해하는 용균작용(Lim과 Kim, 1995; Han 등, 1999; Yun 등, 2001), Bacillus sp., Pseudomonas sp.등이 생산하는 항생물질에 의해 식물병원성 진균의 생육을 저해하는 항생작용(Kim과 Kim, 1997; Jeong 등, 2004; Jung과 Kim, 2004)등과 같은 길항능과, 식물과의 상호작용을 통한 식물생장촉진능(Lim 등, 2009)을 가진다. PGPR 균주의 식물병 억제효과와 식물생장촉진능을 동시에 발휘하게하기 위해선 식물병 억제와 생장촉진 효과가 필요한 기간만큼 지속적으로 토양에서 살아남아야 하지만, 토양에 접종된 미생물은 짧은 시간 내에 그 수가 줄어들고, 토양미생물 군락도 원래의 상태대로 복원된다(Van Veen 등, 1997; Thirup 등, 2003; Park 등, 2009). |
