Journal Title: Лісівництво і агролісомеліорація - Year 2015, Vol 127, Issue
Abstract
The features of Scots pine needles concerning their length, as well as the number, placement and size of resin canals are considered. The level of variability of morphological and anatomical features in the 15 stands from different soil and climatic conditions of Ukraine was assessed. It was found that an average length of the needles of trees in stands of natural and artificial origin is 65,8 to 79,1 mm and the number of resin canals is 11,4 to 16,0. The individual variability of both parameters in forest stands is the medium and high, while between the stands it is low. The tendency to increase the percentage of trees, which have the parenchyma and transitional types of resin canals in the samples, was determined in the direction of Polissja – Forest-Steppe – Steppe.
