【 摘 要 】

The point of the present research was to find possible interrelations between the concentrations of SO 2 , NO xfrom the atmospheric air and S and N from leaves and needles of forestry species. The samples have been collected from six trees, from four stations of air quality control within Cluj-Napoca (CLU-1 - CLU-4). The samples have been collected at the end of September, 2011. One realizes the fact that the forestry species analyzed present considerable differences in their susceptibility to the risk of manifestation of physiological diseases function of concentration of gaseous pollutants in the atmospheric air. In monitoring station CLU-1, at speciesBetula pendulaone can observe the fact that even though none of the pollutants taken into consideration exceed the maximum allowable concentration in the ambiental air, as a result of the interaction between these factors (R = 0.997), the manifestation of the physiological diseases is favoured, foliar lesions being noticed. In station CLU-2, at speciesAcer pseudoplatanuswe can see that even though none of the pollutants taken into consideration exceed the maximum admitted concentration in the ambiental air, due to the interaction between these, the manifestation of physiological diseases is favoured. This can be observed macroscopically on leaves, lesions being seen on the foliar surface. In station CLU-3, at speciesJuglans regiaone notices the fact that even though none of the pollutants exceed the maximum allowable concentration in ambiental air, as a result of the interaction between these (R = 0.995), manifestation of physiological diseases is visible. In station CLU-4, at speciesPinus nigraone notices the fact that although neither SO 2nor NO xexceed the maximum allowable concentration in the air, as a result of the interaction between these two factors (R = 0.882), expression of physiological diseases in needles is favoured. This can be easily observed on the needles.
