Allelopathy of aqueous extract from Artemisia scoparia root on seed germination and seedling growth of four Agropyron plants
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. mongolic...

| Summary: | 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. cristatum×A. desertorum cv. ‘Hycrest-Mengnong’). The results showed that: 1) The aqueous extract from A. scoparia root could significantly inhibit seed germination of A. cristatum×A. 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. cristatum×A. 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. cristatum×A. 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. |
