Abstract

Scots pine (Pinus sylvestris L.) is one of the most important tree species in European forests, characterized by high genetic variability and complex population structure. This research aimed to determine whether there is an interaction between the effects of provenance genetic structure and habitat conditions on the growth of Scots pine in two international provenance tests in Bosnia and Herzegovina, to chose the best provenances for both habitats. For this research, heights and root collar diameters of Scots pine plants on two provenance tests in Bosnia and Herzegovina were measured and the interaction between the effects of provenance genetic structure and habitat conditions for these two traits was estimated based on regression. Eleven provenances represented on both tests were researched. Provenance tests were established in 2012 on two locations with contrasted ecological conditions: Kupres and Žepče. By assessing the interaction between the effects of provenance genetic structure and habitat conditions on Kupres and Žepče provenance tests, two interactions for the height of plants (between Germany NJ2 and Italy I2 and between Austria A2 and Romania R1) and one interaction for the root collar diameter (between Austria A1 and Italy I2) were identified. The number of survived plants and their productivity is different for all provenances in both habitats, indicating that the adaptability of provenances is not only conditioned by their genetic constitution but also by habitat conditions. Considering the productivity of provenances and the number of survived plants in both habitats, Austria A1, Austria A2, Austria A3, and Poland P1 provenances showed the best adaptability. The results of this study can be used in the process of Scots pine breeding and for its conservation by in situ and ex-situ methods.

波黑种源国际试验中种源遗传结构与生境条件对苏格兰松生长影响的相互作用

樟子松（Pinus sylvestris L.）是欧洲森林中最重要的树种之一，具有高度的遗传变异性和复杂的种群结构。在波斯尼亚和黑塞哥维那进行的两次国际种源试验中，本研究旨在确定种源遗传结构和栖息地条件对苏格兰松生长的影响之间是否存在相互作用，以选择两种栖息地的最佳种源。在本研究中，在波斯尼亚和黑塞哥维那的两次种源试验中测量了苏格兰松植物的高度和根颈直径，并基于回归估计了种源遗传结构和生境条件对这两个性状的影响之间的相互作用。对两个试验中代表的11个种源进行了研究。2012年，在两个生态条件不同的地点进行了种源测试：Kupres和žepče。通过评估种源遗传结构和栖息地条件对Kupres和žepče种源测试的影响之间的相互作用，确定了两种植物高度的相互作用（德国NJ2和意大利I2之间以及奥地利A2和罗马尼亚R1之间）和一种根领直径的相互作用。两种生境中所有种源的存活植物数量和生产力都不同，这表明种源的适应性不仅受其遗传组成的制约，还受生境条件的制约。考虑到两种生境的种源生产力和存活植物数量，奥地利A1、奥地利A2、奥地利A3和波兰P1种源表现出最佳的适应性。该研究结果可用于苏格兰松的育种过程，以及通过原位和迁地方法对其进行保护。

期刊介绍： The primary aim of the SEEFOR journal is to publish original, novel and quality articles and thus contribute to the development of scientific, research, operational and other activities in the field of forestry. Besides scientific, the objectives of the SEEFOR are educational and informative as well. SEEFOR should stimulate intensive professional and academic work, teaching, as well as physical cooperation of institutions and interdisciplinary collaboration, a faster ascendance and affirmation of young scientific personnel. SEEFOR should contribute to the stronger cooperation between the science, practice and society, and to the overall dissemination of the forestry way-of thinking. The scope of the journal’s interests encompasses all ecological, economical, technical, technological, social and other aspects of forestry and wood technology. The journal is open for publishing research from all geographical zones and study locations, whether they are conducted in natural forests, plantations or urban environments, as long as methods used in the research and obtained results are of high interest and importance to South-east European and international forestry.
