英文摘要: The distribution of Heterobasidion spp. infection in the root system of Scots pine (. Pinus sylvestris) and the relationship between disease severity and growth was investigated in a mid-rotation in southern Sweden stand nine years after thinning. Twenty-four trees were mechanically uprooted to measure whole root systems and determine the percentage of infected root volume. Annual volume increment was retrospectively calculated using discs cut along the stem. No trees showed aboveground symptoms of infection, however the disease incidence belowground was 87.5% and the percentage of infected root volume ranged between 0% and 32%. The percentage of infected root volume was negatively correlated with the difference in volume increment between the last two adjacent five-year periods, indicating reduced growth in more infected trees, but not with other tree-specific growth characteristics such as diameter at breast height, tree volume or root volume. Annual volume increment of individual trees decreased with increasing percentage of infected root volume. The high incidence of Heterobasidion spp. and reduced volume growth in seemingly healthy Scots pine warrants preventative stump treatment during thinnings to minimize the establishment of Heterobasidion, especially in first rotation forests. © 2014 Elsevier B.V.
