| 摘 要： | 对青蒿母液的乙醇浸提物对小麦的化感作用进行了初步研究，结果表明，青蒿母液的乙醇浸提物对小麦的化感作用总体上呈现出低促高抑的现象，且随着浓度的增大而抑制作用增强；其中浓度为0．1g／L溶液对小麦种子萌发的促进作用最为明显，浓度为0．01g／L的溶液对小麦幼苗的根伸长和苗伸长促进作用最明显，当浓度达到50g／L时完全抑制了小麦种子萌发并且强烈的抑制了小麦幼苗的根伸长和苗伸长。

| Abstract: | A preliminary study was made on the allelopathic effects of the alcohol extract from Artemisia annua L. to evaluate the prospect of application of this plant species in plant growth regulator development. The alcohol extract from A. annua showed different allelopathic effects on seed germination and seedling growth of Triticum aestivum L. In bioassay, seed germination of T. aestivum was markedly promoted by the extract at 0.1 g/L and root elongation and seedling growth was stimulated by the extract at 0.01 g/L, while high concentration of the extract (50 g/L) completely inhibited seed germination and strongly retarded root elongation and seedling growth of the plants. |
