Lesion activity each month at 'the three sites'.

<p>Percentage of active lesions and the growth rate measured as the sum of extension (cm²) of all active lesions each month divided by number of active lesions.</p

Percentage of active lesions each month at Gnesta, Österbybruk and Åkersberga.

Growth rate (mm/day) at different temperatures for seventeen isolates cultured on malt-agar media.

Number of lesions at the four localities each month.

<p>At Gnesta, Österbybruk and Åkersberga one lesion per tree was surveyed, and additional trees were included in the survey during 2008. At Ultuna, all lesions were included in the survey as they emerged on the tree. Lesions were lost during the survey due to the death of the tree or a part of the tree due to another lesion girdling the branch or shoot. At Ultuna, lesions were also lost due to fusion of lesions.</p

Number of genotypes in nine investigated seedlings at Ultuna, distinguished by microsatellite markers.

<p>One sample per lesion was examined.</p
