초록
This study was carried out to allelopathic effects of aqueous extracts on Coronopus didymus in order to investigate the competitive dominant in plant ecosystem and possibility application in natural herbicide. Number of species and species diversity for close to patch of C. didymus was decreased gradually site #1 (7, 1.76), site #2 (5, 1.34) and site #3 (5, 1.25). It was generally decreased the relative germination ratio (r=-0.731, p＜0.01), the mean germination time, the relative elongation ratio (r=-571, p＜0.01, r=-0.730, p＜0.01), the relative fresh weight (r=-0.743, p＜0.01), development of root hairs of receptor plants by concentration of the aqueous extracts from C. didymu. But they were different from the growing regions, the kind of receptor plants and the treatment of the aqueous extracts. Especially, it was differently effected among growing regions that inhibited more radicle than shoot by the aqueous extracts concentration of C. didymus. Total phenolic compound in the aqueous extracts of C. didymus analyzed about 23.0±1.1 mg/g. Total phenolic compounds of soil in survey area was increased gradually site #1 (0.072 ±0.002 mg/g), site #2 (0.082±0.003mg/g) and site #3 (0.092±0.004 mg/g). We think that the aqueous extracts of C. didymu showed allelopathic effects on other plants. Therefore, C. didymu hold the competitive dominant of plant ecosystem in Jeju Island and possibility application of natural herbicide.
Abstract
This study was carried out to allelopathic effects of aqueous extracts on Coronopus didymus in order to investigate the competitive dominant in plant ecosystem and possibility application in natural herbicide. Number of species and species diversity for close to patch of C. didymus was decreased gradually site #1 (7, 1.76), site #2 (5, 1.34) and site #3 (5, 1.25). It was generally decreased the relative germination ratio (r=-0.731, p＜0.01), the mean germination time, the relative elongation ratio (r=-571, p＜0.01, r=-0.730, p＜0.01), the relative fresh weight (r=-0.743, p＜0.01), development of root hairs of receptor plants by concentration of the aqueous extracts from C. didymu. But they were different from the growing regions, the kind of receptor plants and the treatment of the aqueous extracts. Especially, it was differently effected among growing regions that inhibited more radicle than shoot by the aqueous extracts concentration of C. didymus. Total phenolic compound in the aqueous extracts of C. didymus analyzed about 23.0±1.1 mg/g. Total phenolic compounds of soil in survey area was increased gradually site #1 (0.072 ±0.002 mg/g), site #2 (0.082±0.003mg/g) and site #3 (0.092±0.004 mg/g). We think that the aqueous extracts of C. didymu showed allelopathic effects on other plants. Therefore, C. didymu hold the competitive dominant of plant ecosystem in Jeju Island and possibility application of natural herbicide.
