中文摘要	为研究猪毛蒿与其他物种之间的相互影响,该文分析了不同质量浓度(0.05、0.5、1.0、2.0、5.0、10.0 mg/mL)猪毛蒿根水浸提液对蒙古冰草(Agropyron mongolicum)、扁穗冰草(Agropyron cristatum)、沙生冰草(Agropyron desertorum)、蒙农杂交冰草(A. cristatum*A. desertorum cv.Hycrest-Mengnong')4种冰草种子萌发和幼苗生长的化感作用。结果表明:1)不同质量浓度猪毛蒿根水浸提液能明显抑制蒙农杂交冰草种子萌发,而对其他3种冰草影响不显著(P>0.05)。2)猪毛蒿根水浸提液对4种冰草幼苗生长具有低促高抑效应,但大部分与对照相比差异不显著(P>0.05)。3)猪毛蒿根水浸提液对4种冰草种子萌发和幼苗生长的化感作用综合效应的强度依次为:蒙农杂交冰草>蒙古冰草>扁穗冰草>沙生冰草,其中对蒙古冰草产生明显的促进作用(P<0.05),在0.5、1.0、5.0 mg/mL质量浓度处理下对蒙农杂交冰草产生明显的抑制作用(P<0.05),说明这2种冰草对猪毛蒿根水浸提液具有更强的敏感性。本研究结果可为荒漠生态系统群落组建和植被恢复提供理论依据。
英文摘要	In order to research the interaction between Artemisia scoparia and other species, we analyzed the allelopathy of different concentrations (0.05, 0.5, 1.0, 2.0, 5.0, 10.0 mg/mL) of aqueous extract from A. scoparia root on the seed germination and seedling growth of four Agropyron plants (A. mongolicum, A. cristatum, A. desertorum and A. cristatumA. desertorum cv.Hycrest-Mengnong'). The results showed that: 1) The aqueous extract from A. scoparia root could significantly inhibit seed germination of A. cristatumA. desertorum cv. Hycrest-Mengnong'(P<0.05), but it had non-significant effects on the other three Agropyron plants (P>0.05). 2) The effects of the aqueous extract from A. scoparia root on seedling growth of the four Agropyron plants presented the role of promotion in the low concentration and inhibition in the high concentration, but most of them had no statistically significant differences from the contrasts (P>0.05). 3) The allelopathic comprehensive effect of the aqueous extract from A. scoparia root on seed germination and seedling growth of the four Agropyron plants was in order: A. cristatumA. desertorum cv.Hycrest-Mengnong'>A. mongolicum>A. cristatum>A. desertorum. The seed germination and seedling growth of A. mongolicum had significantly positive reaction (P<0.05), but those of A. cristatumA. desertorum cv. Hycrest-Mengnong' had significantly inhibitory reaction (P<0.05) on the concentrations of 0.5, 1.0 and 5.0 mg/mL, which indicated that these two Agropyron plants had stronger sensibility to the aqueous extract. The above results could provide the theoretical basis for community construction and vegetation recovery in the desert ecosystem.
