本试验应用室内培养皿生物测定方法，研究了青海省野胡萝卜水浸提液对野燕麦及旱雀麦种子萌发和幼苗生长的影响。结果表明野胡萝卜水浸提液对野燕麦及旱雀麦具有一定的化感效应。野胡萝卜水浸提液对旱雀麦种子萌发和幼苗根长、苗高和鲜质量具有一定的影响，随着浸提液浓度的升高，其抑制效果越明显。对野燕麦而言整体表现出了“低促高抑”现象，即低浓度下促进，高浓度下抑制。通过RI值比较可知：地下部分的化感强度要大于地上部分。

Indoor petri dish bioassay was adopted to study the impact of Daucus carota Linn. aquatic ex?tract on the seed germination and seedling growth of wild oat and Bromus tectorum L. The results showed that the Daucus carota Linn aquatic extract had a certain allelopathic effect on wild oats and Bromus tectorum L.. The aquatic extract had a certain influence on seed germination,the seedling root length,the seedling height and fresh weight of Bromus tectorum L..The inhibitory effect became more obivious with the increase of aquatic extract concentration.For wild oat,it was low-promoting and high-repressing.In other words,it was facilitating when its contraction was low and inhibiting when its contraction was high. The allelopathic strength of under?ground parts was higher than that of overground parts according to the comparison of RI values.
