INFLUENCE OF GENTETICS (FAMILY) AND FOREST TYPE ON PORDUCTIVITY OF SCOTS PINE STANDS ON DRY MINERAL SOILS
Abstract
Scots pine (Pinus sylvestris L.) stands are regenerated by planting, and only small portion (c.a. 13%) by self-seeding in Latvia. Seeds for plant production are collected only in seed orchards ? thus represent the results of tree breeding. Aim of our study was to assess the growth and damages as determined by forest type and genetics in Scots pine stands at the age of first commercial thinning. Tree parameters were measured in Scots pine open-pollinated progeny trials on mineral soils, differing by fertility (poor Cladinoso- callunosa and rich Hylocomiosa), including 35 families in 4 replications in each trial, at the age of 40 years. There were statistically significant differences among the forest types in parameters characterizing tree growth (diameters, height), however, the values of best performing families in poor growing conditions exceeded the values of worst performing in better growing conditions. Genotype x environment interaction effect on tree growth was significant, however, it could not be practically used ? establishment of separate seed orchards for different forest types would be too costly. Therefore selection of best performing genotypes across range of conditions is proposed. Selection differential is similar on both studied forest types, with selection intensity of 10% leading to increase of 6.3-8% in height and diameter of the trees.
