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.
