FIGURE 5 Effects ofElymus nutans extracts on growth of highland grasses. Values are mean ± SD (n=5). Different letters denote significant differences between treatments with a > b > c, the same below.
The comprehensive allelopathic effect index of drooping wildryegrass on the tested grasses see Figure 6. The maximum germination allelopathic index was noted for Chinese fescue (-0.772), and the minimum is Kentucky bluegrass (-0.120). The inhibition of the extracts on Chinese fescue was seed germination and on crymophila bluegrass, Kentucky bluegrass, Siberian wildryegrass and drooping wildryegrass were root and shoot growth.
