Other claims from this paper (11)
- Intervention effect High concentrations of the Houttuynia cordata water extract suppressed growth of lettuce, carrot and cabbage.
- Intervention effect Low concentrations of the Houttuynia cordata water extract sometimes stimulated growth of the test plants.
- Method / resource Root-length inhibition ratio was higher than stem inhibition ratio, so root length is the more suitable allelopathy bioassay index.
- Intervention effect WES of H. cordata from Huangkeng Town inhibited lettuce stem height by 43.7% (IR).
- Intervention effect WES of H. cordata from Xiaohu Town inhibited carrot root length by 55.9% (IR).
- Intervention effect WES of the underground part inhibited carrot stem height by 46.7%.
- Intervention effect UWES of H. cordata from Huangkeng Town gave the highest root-length inhibition in cabbage (75.8%).
- Intervention effect AWES of H. cordata from Huangkeng Town gave the highest stem-height inhibition in cabbage (68.5%).
- Intervention effect Elution with polar resin ADS-21 weakened the growth suppression by the WES relative to non-eluted WES.
- Intervention effect Elution with non-polar resin ADS-5 strengthened the growth suppression by the WES relative to non-eluted WES.
- Mechanism Non-polar substances are supposed to play an important role in allelopathy, while polar substances may weaken it.
