| 中文摘要 | Under field conditions, Chinese fir has poor establishment and less productivity when seedlings are replanted to the same area after harvest. Experiments were conducted to determine if allelopathy specifically autotoxicity is responsible for the replant problem. Aqueous extracts of plant tissues and litter were examined for their effect on seed germination and seedling growth. Further soil amended with litter, bark, branch, leaf and root material was examined to determine any possible effect on seedling growth. Depending on the type and concentration of the tissue extract, aqueous extracts of Chinese fir inhibited, stimulated, or had no effect on the seed germination and seedling growth. Ten % (w/v) extracts of roots, fresh leaves and litter and 1% (w/v) extracts of roots inhibited the Chinese fir seed germination. While bark extracts (0.1% w/v) stimulated the seed germination, Chinese fir root, fresh leaves and litter placed on the soil surface reduced the seedlings growth in pat experiments. However, Chinese fir branches and bark had no significant influence on the seedlings growth. Paper chromatography and HPLC revealed that nine phenolics (syringic, gallic, protocatechuic, o-coumaric, m-coumaric, p-coumaric, p-hydroxybenzoic, vanillic, and ferulic acids) were present in the Chinese fir extracts. These phenolic compounds appear to be related to the autotoxicity of Chinese fir. |
