Verbatim
e0“A Similar trend of allelopathy on lettuce,carrot and cabbage was found on the water extraction solution(WES)of the underground and aboveground parts of Houttuynia cordata Thunb”
e1“After WES was eluted by polar resin ADS-21 and by non-polar resin ADS-5,the suppression of the elution solution of ADS-21 to the root and stem growth was weaker than the non-eluted WES,while the suppression of the elution solution of ADS-5 to the root and stem growth was stronger than the non-eluted WES”

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 Aboveground-part WES at 1:10 inhibited lettuce root growth by 77.5%.
- 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.
- Mechanism Non-polar substances are supposed to play an important role in allelopathy, while polar substances may weaken it.
