colonisation - Opis:
- Phytophthora cinnamomi was isolated from nurseries and in the stand. Declining pedonculate seedlings and adult oaks Quercus robur L showed disease symptoms. Affected seedlings were dying as quick as severe damage of root system occurred. Infected trees showed dieback of crowns and characteristic dark exudation on stems. Beneath the bark necrosis of bast tissue was observed. Apart of P. cinnamomi such fungal pathogens as Fusarium avenaceum and F. oxysporum were isolated from diseased plants. The number of obtained isolates of P. cinnamomi could be probably higher if they were not quickly overgrown by Mucor, Chaetomium and Trichoderma spp. Isolates of P. cinnamomi from oak, pine and spruce cause stem rot of oak seedlings and necrosis spread about 8,5−10,4 mm/24 hr. On infected parts of oak the fastest spread was observed on roots and the slowest on leaf blades.
