Results for Scots pine and Norway spruce are discussed from a number of studies mainly in S. Finland by different authors. From autocorrelation and cross correlation analyses it is concluded that in Scots pine the most important factors were the effective temperature sum for the latter part of the growing season and, especially on arid sites, the precipitation sum during May-July; in Norway spruce the most important factor was the effective temperature sum of the growing season, although warm periods in the latter parts of the previous summer had a negative effect on indices.
