Abstract:

Dendroclimatology is one of the modern methods of paleoclimate reconstruction with high time resolution equal to one year. To date, to solve the problems of dendroclimatology, along with the chronologies of the width of annual rings, the chronologies of the parameters of the cellular structure and chemical composition of annual rings are used, which can correlate with climatic parameters no worse, and sometimes even better, than the width of annual rings. Therefore, an urgent task is to search for new parameters of the cellular structure, the chronologies of which could improve the reconstruction of paleoclimate. One of the poorly studied cellular parameters is the X-ray density of cell walls, the value of which reflects the total concentration of both organogenic elements and macro- and microelements necessary for the vital activity of a woody plant. The radiographic density of the cell walls of larch annual rings (Larix sibirica Ledeb.) is calculated by the author’s method using data of the density profile of annual rings and cell sizes of tracheids, such as the radial, tangential size of cells and the thickness of their cell wall. The main statistical characteristics of the radiographic density of the cell wall, its distribution within the annual rings, and the relationship with cellular parameters are considered. The analysis of the results shows the presence of a relationship between the radiographic density of the cell wall and its thickness, radial size of cells, cross-sectional area of ​​the cell and cell wall and the specific gravimetric mass of tracheids.

Keywords: radiographic density of cell wall, gravimetric density, cell wall of tracheids, annual rings, X-ray densitometry, cellular parameters, larch.
