| 中文摘要: |
| 以沿阶草(Ophiopogon japonicus)和三叶鬼针草(Bidens pilosa L.)幼苗为材料，研究了土壤、吸湿塑料泡棉、
细河沙和营养水培液4 种不同培养基质对化感作用生物测定结果的影响。结果表明，不同培养基质条件下，不同浓
度沿阶草叶浸提液（1颐40、1颐200、1颐400 和CK）对三叶鬼针草幼苗根长、株高和生物量等生物测定指标变化影响的规

验培养基质的选择对试验结果产生显著影响，不同培养基质可能获得显著不同的试验结论。 |
| 英文摘要: |
| Effects of four culture media (soil, sponge, sand and liquid) on the results of allelopathic potentials of dwarf
lilyturf (Ophiopogonjaponicus) seedlings against Bidens pilosa L. were investigated. The results showed that the effects of
different concentration (140, 1200, and 1400) of leaf extracts from dwarf lilyturf on the growth of B. pilosa were significantly
different among the four culture media. Meanwhile, the root morphological structure (root length, root surface area and root
volume, etc.) of B. pilosa also differed when the plants were cultivated in different culture media. Seletion of culture
medium could significantly affect the outcomes of study. |
