The paper presents results of measurements for tracheid lengths in annual growth rings in spruce wood classified as resonant wood. Annual rings came from the mature wood zone. Moreover, cellulose microfibril angle (MFA) was determined in the S2 layer of the secondary cell wall. This parameter was measured in tangential tracheid walls. Mean values of both tracheid lengths and MFA in the experimental annual growth rings showed slight fluctuations and the relationship of these values was described using a linear function.

The paper presents results of measurements for annual ring widths in reaction, opposite and lateral wood formed in the same vegetation periods in pine (Pinus sylvestris L.). In the compared wood tissues tracheid lengths was also measured. The widest annual rings were found in the reaction wood zone. In that area of the stem cross-section tracheids were by approx. 20% shorter than those located on the opposite side of the pith.

The aim of the present study was to establish the value of desorption stresses and the rate of their increase in the samples of juvenile and mature birch wood as well as in aspen samples of different physiological age. The stress value was calculated on the basis of the measurement of the force necessary to restrain shrinkage in the sample being dried. Additionally, moisture strain and mechanical-moisture strain (both real and apparent) were measured during the experiments. The samples were dried at temperatures of 30, 50 and 70°C. It was concluded that both the rate of increase and the absolute values of stress and strain are different in juvenile and mature birch wood. Also in aspen they depend on the physiological age of the wood tissue. Juvenile birch wood and the physiologically younger aspen proved more susceptible to strain caused by desorption stresses.
