Self-pruning of trees as a basis for the evaluation of the timber quality of Scots pine trees (Pinus sylvestris I.) growing on forest soils and former farmlands .The study made an attempt to determine the timber quality of pine trees derived from the former farmlands and typical forest soils on the basis of the stem self- pruning process of branches. The obtained results show a distinct difference in the degree and dynamics of the stem self-pruning of branches of pines developed in conditions of the former farmland and forest sites. The performed experiments covered just a small fraction of a wide range of issues associated with the quality of wood determined on the basis of the process of stem self-pruning of branches, especially in stands which developed in conditions of the former farmland. Further studies in this area are required.

The study was conducted on 28 growing female Wistar rats, fed ad libitum for 84 days with four different diets: preferred poor, preferred rich, recommended and Labofeed B. The diet intake, feed efficiency, weight/length ratio, serum TG, TC and HDL-C levels were determined. Results were verified statistically using one-way ANOVA and the Scheffe test. The poor preferred diet with predominating fruit and vegetables, in comparison to the rich preferred diet, containing sweets, lowered the risk of obesity and atherosclerosis. The recommended diet, based on the model food ration for girls aged 13-15 years, lowered the risk of these diseases too.
