Abstract The article presents the results of research in the pine plantations located in the green belt of the city of Astana, the dry steppe zone of Northern Kazakhstan, and in the research, the data on biomass and carbon content in various fractions of Scots pine were obtained. Assessment of morphometric parameters of the pine stands was carried out by measuring tree height and trunk diameter at breast height (DBH); to determine the carbon content, laboratory analytical methods were used. Samples were taken from each element of biomass (branches, trunk, leaves, and bark) of Scots pine, in triplicate. After that, the green mass was weighed on the analytical scales to within 0.001 g. The samples were then dried to a constant weight at a temperature of 65°C. In laboratory samples without mineralization, the content of carbon was determined using element analyser. Regression equations were used to calculate the biomass of stocks. To measure the taxation indicators and sampling of plantations, trial plots were laid in triplicate for trial plots, the height of plantations varied on average from 5.8 m to 8.4 m on the plotted trial plots, and the diameter of the trunk varied from 7.7 cm to 8.8 cm. The correlation between plant height and stem diameter was 0.745. As the studies of chemical composition in needles, bark, trunk and branches of pine trees showed, the amount of carbon was from 50.03 to 51.33%. Thus, the study of the chemical composition of the pine plantations showed that the greatest content of chemical elements, such as carbon, was in tree needles. The accumulation plantations of Pinus sylvestris L. in the green belt of the city of Astana were sequestrated 973.3 tons of carbon in the above-ground biomass varied from 2.9 to 4.8 t/ha.

Tracheid Length

Abstract Variation of tracheid length was studied within individual annual rings of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) from the pith to the bark. The material consisted of six Scots pine and six Norway spruce trees growing on sites of both low and high fertility. Microtome sections of 0.25 mm thick were cut from annual rings 7, 20 and 50 counted from the pith outwards, i.e., juvenile, transition and mature wood, respectively. After maceration, tracheid lengths were separately measured in each sample. In juvenile wood of Scots pine, tracheids were on average 17% longer in the latewood than in earlywood. However, in juvenile wood, the first formed earlywood tracheids were slightly longer than those in the middle of the earlywood zone. In the transition and mature wood of Scots pine, the increase in tracheid length was more gradual from earlywood to latewood, and no significant differences were found between earlywood and latewood. In Norway spruce, tracheids were 2–4% longer in the latewood than in earlywood. In general, tracheid length is highly variable within annual rings and the variation can differ from ring-to-ring even within the same tree.

The study makes an attempt to analyse the width of annual rings, the width of the latewood zone and the proportion of the latewood within juvenile wood along trunks of Scots pine (<em>Pinus sylvestris</em> L.) trees and to verify the hypothesis about the heterogeneous properties of juvenile wood in a single trunk. It was found that the above-mentioned macrostructural elements of wood structure showed a curvilinear correlation with the height of measurement points along the tree trunk. As the distance from the base of trunk increased, the width of the annual ring and the width of the latewood zone decreased, while the proportion of the latewood increased. These types of changes can affect positively physical and mechanical properties of wood tissue. It can be assumed that there is a mechanism which modifies properties of juvenile wood causing axial diversification of the analysed type of wood tissue. It is probable that axial heterogeneity results in advantageous changes in the mechanics of the tree trunk.
