Other claims from this paper (7)
- Association The path model explained 80.0 and 70.1% of variation in rust intensity in cultivated and wild plants.
- Association Precipitation was the key factor determining rust intensity in cultivated and wild plants (path coefficient 0.313 and 0.544).
- Association Topsoil water content in cultivated plants was a critical determinant of rust intensity via the microclimatic factor (path coefficient 0.831).
- Association Total vegetation coverage in wild plants was a critical determinant of rust intensity via the microclimatic factor (path coefficient 0.231).
- Association Apocynum venetum density was the main host factor, with contribution coefficient 0.989 and 0.894.
- Association The effect of host density on rust intensity via the microclimatic factor exceeded that via the inoculum factor.
- Association The indirect effect size in wild plants was 0.200 and lower than in cultivated plants, with a dilution effect from weed.
