QUALITY RESEARCH OF SCOTS PINE (PINUS SYLVESTRIS) CONES AND SEEDS

Abstract

In this paper, based on the literature analysis, several objectives were identified and addressed to determine the morphological differences of cones in different seed plantations and to calculate the seed yield from cones from different seed plantations. The cones analysed were collected from the seed plantations in Ukmergė, Trakai and Druskininkai and from the genetic nursery in Alytus. The cones were analysed in 2023 and 2024. The information in the literature on average cone weight and seed yield was found to be consistent with the results obtained during the analysis. In addition to this, analysis showed that the morphological characteristics of mature pine cones differ in different areas, for example, in Alytus and Druskininkai, the dominant group of pine cones were the pine cones from 5 centimeters length group, while in Ukmergė and Trakai - 4 centimeters group.
