Development of Biomass Expansion Factors in Albania's oak forest stands

The results of the study of solid-volume/stacked-volume ratio, the relationship between heights and diameters, as well as the dimensional and qualitative structure of oak stems in mature and overmature forest stands are presented. Correlation analysis is performed and interrelations between taxation indicators are evaluated. Mathematical models of height, form factor and dimensional-qualitative structure of tree stems were developed, on the basis of which volume tables, a class scale of heights and tables of the dimensional and qualitative structure of tree oak stands were constructed. It was established that the percentage of output of coarse, medium and small merchantable wood, firewood and waste wood doesn’t significantly depend on the class of heights. Comparison of the developed standards with the current ones showed that the yield of commercial timber according to the results of the conducted study is 5% on average, and that of coarse commercial wood for stems with a diameter of more than 48 cm is 3-8% less than the current standards.

Statistical Indicators

Calculated statistical indicators of numerical equation coefficients indicate significance of obtained regressions for each TFC (FT). The resulting regression equation allows carrying out calculations for all oak forest TFC (FT) of Voronezh region, in the age range of stands from 10 to 300 years, for completeness – from 0.3 to 1.0, the share of participation of oak in the composition of forest stands from 1 to 10 units. Developed forst typological scales for natural seed oak forests can detect patterns of increase of growth in trophotopes and ecotypes and within ecotypes and trophotopes – by hygrotopes.

Abstract In this study, the biosynthesis of the plastid pigments chlorophyll a and b was examined for the most common shrubs in hornbeam-oak forest stands of the Western forest-steppe zone of Ukraine. The characteristics of the pigments’ biosynthesis were determined in terms of plant species, vegetation period and growth conditions (under canopy cover and out in the open). The gathered data on the changes of the pigment complex with respect to the examined variables confirms the sensitivity of plastid pigment biosynthesis to environmental factors.
