| 摘 要： | 通过室内培养皿法,研究了银胶菊花水浸提液及其乙酸乙酯相、正丁醇相、剩余水相不同极性组分对苘麻和稗种子萌发及幼苗生长的影响。定性测定结果表明,在50 g/L浓度处理下,水浸提液完全抑制苘麻和稗种子萌发,对苘麻和稗根长、芽长、鲜重抑制率分别为82.6%、89.1%、84.3%和91.7%、55.8%、39.1%;正丁醇相抑制苘麻种子萌发和幼苗生长最强,乙酸乙酯相抑制稗种子萌发和幼苗生长最强。定量测定结果表明,在1 g/L浓度处理下,乙酸乙酯相生物活性最高,苘麻和稗种子萌发率分别为13.3%和33.3%,对苘麻和稗根长、芽长、鲜重的抑制率分别为63.1%、80.0%、58.3%和51.3%、26.7%、23.3%。

| Abstract: | The allelopathic effect of a Parthenium yh sterophorus L.flower aqueous extract and its ethyl acetate,n-buta-nol,and residual water fractions on seed germination and seedling growth of Abutilon theophrasti Medic.and Echinochloa crusgalli （ L.） Beauv.were studied by petri dish bioassays.Seeds of A.theophrasti and E.crusgalli failed to germinate in an aqueous extract of 50 g/L;the inhibition rate of root growth,shoot growth and fresh weight were 82.6%,89.1%and 84.3%for A.theophrasti,respectively and 91.7%,55.8%and 39.1% for E.crusgalli,respectively.With the butanol extract （50 g/L） the inhibition of root growth,shoot growth and fresh weight were 63.1%,80.0% and 58.3% for A. theophrasti,respectively,and 51.3%,26.7%and 23.3%for E.crusgalli,respectively.The germination rate of A.theo-phrasti and E.crusgalli were 13.3%and 33.3%,respectively. |
