| 摘 要： | 在实验室和温室条件下，用从石菖蒲根茎中提取的挥发油经减压蒸馏获得的组分四，对稗草、鳢肠和水稻的萌发与生长进行了生物学效应测试。结果表明，在低浓度时促进供试植物的萌发和生长，而在高浓度时则抑制萌发和生长。实验室培养皿条件下，50～400mg／L浓度抑制作用产生并逐渐增加，400mg／L以上达到90％或更高。但是，温室盆钵条件下，3000mg／L时才出现抑制作用，在1000mg／L以下均表现促进作用。

| Abstract: | The laboratory and glasshouse experiments were conducted to evaluate the effect of fraction 4 on seed germination and seedling growth of barnyardgrass (Echinochloa crusgalli (L.) Beauv.), eclipta(Eclipta prostrata(L.) L.) and rice(Oryza sativa L.), which was separated from the essential oil of rhizomes of grass-leaved sweetflag(Acorus tatarinowii) that was dephlegmated at low pressure. A common phenomenon was observed in both laboratory and greenhouse trials, that is, seed germination and seedling growth was inhibited at higher concentration but slightly increased at 50 mg/L or lower concentration. Under laboratory conditions, inhibition was observed at concentration from 50~400 mg/L and more than 90% inhibition with >400 mg/L. However, under glasshouse conditions, inhibition occurred at 3000 mg/L or higher while increase of the growth was observed at 1000 mg/L or lower concentration. |
