잡초의 수용 추출물이 수종 작물의 초기 생장에 미치는 상호대립 억제 작용의 효과
이상금,신우진,한기배,김옥임,하상영 東亞大學校 2003 東亞論叢 Vol.40 No.-
Lettuces, radishes and corn had been raised for thirty-two days in portion to the consistency of a soluble extract from weeds, and then the result of allelopathy action affecting the growth at their early stage was admitted by statistical significance. The result of a growth test ; Amaranthus mangostanus showed the decrease of the leaf number, however, the leaf number of crops decreased as the consistency goes higher. The length of stem was shorter in the group of the high consistency than control group. The root showed a remarkably constrained growth at all level of consistency compared to control group, and the growth was constrained more strongly as the consistency goes higher. The degree of development in lateral root showed no difference at each level of the consistency, and as the consistency of weeds goes higher, the rate of dried material increased. The analysis on nutritions in cultivation soil showed that the remains of nutrition elements increased as the consistency increases, NH4-N and N03-N result in the reverse. The allelopathy action is stronger in Amaranthus mangostanus than Setaria glauca.
