ArticleThe preservation of natural forests through the establishment of industrial wood production plantations via the new, fast growing Robinia pseudoacacia ‘Turbo Obelisk’ varieties and new cultivation technologies

No results found.After decades of research and development, Silvanus Forestry Ltd. and HungaroPlant Ltd. have successfully propagated the Robinia pseudoacacia ‘Turbo Obelisk’ variety group and developed the necessary cultivation technologies, specifically for intensive industrial wood production plantations. In comparison to the Hungarian and traditional black locust varieties and cultivation technology, industrial wood production plantations established with our variety group and using our cultivation technologies can produce twice as much timber yield and industrial timber yield, considering 15-year rotation periods. These parameters are comparable with the performance of the widespread Eucalyptus and Pinus plantations in the subtropics. Our varieties and cultivation technologies, however, are also usable in subtropical, temperate, as well as tropical climates. The outstanding yields achieved by the ‘Turbo Obelisk’ varieties and the extremely high industrial wood output can provide a significant contribution to the conservation and maintenance of natural ecosystems, whilst the CO2 sequestration per unit area per time is also several times that of natural forests. A particular advantage to emphasize is long term carbon sequestration due to the high percentage of industrial wood yield. Increasing the exceptional tolerance of black locust against drought, pollution and low-quality soils, our varieties are exceptionally suitable for the utilization of marginal agricultural areas, the agricultural utilization of which would otherwise create an economical loss. This can also significantly increase the advancement of less developed regions. In addition to plantation cultivation, it also provides a cost-effective solution for the establishment of protective forest belts, road-side plantings, quicksand fixation and soil renovation. Delicious honey production is also a possible revenue stream. The global exploitation of the research findings has begun, having already successfully established test plantations in China, India, and Pakistan, as well as in several European countries.

DocumentIsolation of DNA from preserved woods for identification of wood species through genetic analysis regardless of the age of wood production

No results found.Species identification of wood provides important information for archaeology, restoration of cultural assets, preventing illegal logging, and more. Wood species are usually identified based on their anatomical features with the use of a microscope. However, this method may not be able to distinguish between anatomically similar species or subspecies. To overcome this problem, wood species need to be identified at the molecular level using DNA sequencing. However, unlike living plant cells, wood is difficult to pulverize using a mortar, and DNA extraction from dried wood is challenging. To solve these problems, we propose a pretreatment method in which wood is pulverized using 60-grit sandpaper and hydrated with water for 2 days. Using this method, we were able to stably amplify the rpoB gene from the extracted DNA of Pinus rigida. In addition, sequence analysis of the rpoB gene revealed six single nucleotide polymorphisms (SNPs), which classified the rpoB sequences in the genus Pinus into five groups. Our data indicate that although these SNPs were not suitable for species identification, they can potentially be used to determine the origin of different wood subspecies or individual samples of wood.

ArticleForest plantations for wood growing in the European north of Russia
XV World Forestry Congress, 2-6 May 2022

No results found.The Russian Federation has accumulated quite a lot of experience in plantation forestry. An urgent issue of returning unused agricultural land to economic circulation can be solved by creating plantation crops on these lands, which contributes to the achievement of the Sustainable Development Goals on rational forest management, restoration, afforestation and reforestation (SDGs 2, 12, 15 and GFGs 1 and 2). Research on the creation of targeted forest plantations in the European North of Russia was carried out within the framework of a state assignment. Well-grounded conclusions on the choice of species for targeted plantation cultivation were made. Preference should be given to aboriginal species (Scots pine, European spruce). However, one of the promising fast-growing species suitable for the pulp and paper industry in temperate countries is Lodgepole pine (Pinus contorta Loud. var. latifolia S. Wats.), naturally growing in North America. Based on long-term research, the most suitable origins of Lodgepole pine were selected – located in regions of the most northern Canadian origin (Yukon), where it grows at the northern limit of the distribution of forest species. The advantage of Lodgepole pine over local coniferous species was revealed while growing on industrial forest plantations, where, by the age of 40-50 years, it forms 250-300 m3/ha of low-resinous wood, suitable for both sulfate and sulfite pulping and is 70% more productive than local spruce and pine. In the research process, the basic requirements for plantation crops in the European North of Russia were developed, under which plantations justify their purpose. One of the main innovative areas of research is the development of technology for creating forest plantations on lands that have come out of agricultural use.
