Book excerpt: Since the Scots pine species is most important in Eurasia, it was considered necessary to involve authors from as many countries as was possible including Eastern Europe and U.S.S.R. During the 18th IUFRO World Congress in Ljubljana, Yugoslavia, in September 1986, details were worked out for the contents of this book.This book is a truly international effort, prepared in the traditional IUFRO spirit of selfless co-operation. In all, 24 authors from 9 countries are involved. Each chapter was reviewed by two editors from two different countries.

Book excerpt: S2Genetic and environmental components of variance for 2-year heights of offspring from inter- and intra-provenance matings in Scotch pine (Pinus sylvestris L.) were studied to determine which provenances and selection methods should be used in a program to improve ornamental and Christmas trees. The study represents 11 experiments (parental groups), consisting of families from 7 diallel matings minus selfs in 5 different provenances, 3 factorial matings between provenances, and 1 from open pollination. The seedlings for the 11 experiments were grown in pots and in a nursery for 2 years. Heritability estimates of 2-year height from inter- and intra-provenance matings tended to be larger on a family basis than on an individual basis, with the larger estimates being from nursery evaluations. In general, additive genetic variance was larger than dominance variance, although dominance variance increased in provenance hybrids. Nursery evaluation was preferred to pot evaluation of 2-year height because heritability estimates were larger and error variances were smaller for the experiments evaluated. Individual selection in the nursery within the German provenance seems to be the best method for improvement of 2-year height of the provenances evaluated in this study, although the rate of improvement in the Spanish provenance may be greater. Simple recurrent selection would be a good method for improvement of traits important to the Christmas tree producing industry. S3.

Available in PDF, EPUB and Kindle. Book excerpt: Genetic differentiation in phenotypic traits among populations from heterogeneous environments is often observed in common-garden studies on forest trees, but data on adaptive variation in Scots pine (Pinus sylvestris L.) in Scotland are limited. As a result, current seed transfer guidelines are based on earlier molecular marker studies and do not take into account environmental or adaptive genetic variation. An analysis of spatial variation in climate showed substantial differences in temperature and precipitation among the native Scots pine sites in Scotland. To investigate whether differentiation in response to environmental variation has occurred in Scotland, a glasshouse-based common-garden trial of ~3,360 seedlings from 21 populations and 84 open-pollinated families was established in 2007. At the beginning of the 2nd growing season, timing of bud flush showed evidence of genetic differentiation among populations, with those from cooler origins generally flushing earlier. Variation was also found among families within populations, suggesting that the trait is genetically controlled. Populations and families showed different levels of variability in this trait which could be partly due to variable levels of temporal climate fluctuation in different parts of Scotland. Chlorophyll fluorescence was used to examine drought response in three-year old seedlings from five populations on sites that experience contrasting levels of annual rainfall. It was found that the response was not related to rainfall, but possibly to more complex moisture variables that also take into account additional factors such as evaporation. Also, photosynthetic capacity in response to cold winter temperatures varied significantly among eight populations that were kept outdoors, and the largest reduction was seen in seedlings from the mildest, most maritime coastal site. The following spring, height growth and needle flush started earlier in seedlings from cooler locations. Earlier studies on genetic diversity of native pinewoods have shown high levels of selectively neutral variation in this predominantly outcrossing conifer, and a mating system analysis with a limited number of microsatellite markers supported this pattern. Together, these data suggest that despite significant historic population size decrease, environmental gradients have resulted in genetic differentiation among native pinewoods. In order to minimise the risk of planting poorly-adapted stock and to maximise the success of replanting programmes, it is important that the origins of planting stock are carefully considered in management guidelines for the species.
