Ilie Covrig, Ioan Oroain, Antonia Odagiu, Petru Burduhos


The pine trees may support the consequences of the action of a series of various natural harmful factors, as break downs determined by strong winds, storms, or large amounts of snow, pathogens and mites’ attacks, and also anthropogenic harmful factors. The research was developed in Reghin Forestry District, arrangement unity Breaza 2, county of Mureş, in the year 2012. The biological material consisted of pine (Pinus nigra) trees, 40 years old. The following climatic and pine tree developmental parameters were monitored: temperature, humidity, and rainfall regimen, pine height, pine average diameter, and pine slenderness ratio. The experimental research emphasizes climatic conditions represented by an annual temperature of 9.27ºC, atmospheric humidity of 71.17%, and rainfall regimen of 5.48 mm. The averages of the diameter of the pine trees is of 11.76 m, of the height of 11.19 m, and of the slenderness ratio of 0.95, while the statistical analyze is repr4esentative. A strong positive correlation between pine trees’ diameter and height, of 88.70%, representative for 78.60% of the sample may be mentioned, ande between diameter and slenderness ratio, the correlation is equal to 0.452, representative t for 20.40%.
