    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Picea abies; Multiple stress; Mineral nutrient balance; Liming; Lichen indices; Fagus sylvatica; Cryptococcus fagisuga; Excess nitrogen; Vitality fertilization; Plant ecology; Växtekologi;

    Sammanfattning : Strong temperature fluctuations and pathogen attacks can cause bark lesions, visible signs of wounds in the phloem and cambium. Pathogenic insects and fungi are able to invade lesions that have not healed, further increasing the damage. LÄS MER
