Effects of Drought by Polythylene glycol Solution on Seven Grasses Germination

Polythylene glycol을 이용한 모의적 토양수분 조절방법이 목초의 발아에 미치는 영향과 유효성

The present study elucidates the effect of drught by polyethylene glycol solution on germination of five temperate and two tropical grasses. The results obtained can be summarized as follows: 1. The germination percentage of seven grasses decreased with increasing concentration of polythylene glycol. 2. The germination pattern hi higher concentration of polyethylene glycol showed similar trends to the emergence pattern under drought stress in soil condition. 3. The treatment of 30g is most useful at this study. Therefore, polythlene glycol was the appropriate to creat the drought condition of soil.
