ABSTRACT
The investigations made by us about the micromorphology of the foliar surfaces of two species of gymnosperms in the industrial areas Bicaz (the Neamt District, Romania). The investigations of electronic microscopy (S.E.M.) made up at the level of necrotic and/or chlorosis surfaces (top, middle, basis) of the acicular leaves of Pinus sylvestris and Pinus nigra showed changes of the cuticular surface, their contortion, caused by the total disappearance of the parallelism between the cuticular prints, the chaotic setting of the stomata and their less dimensions, the presence of cuticular clefts, the closing of the ostiols with amorphous wax, which could be an indicator of the "suffering" of the leaf mesophyll in general. The analysis of the foliar surfaces by means of the S.E.M. revealed the role of the solid deposits of industrial origin in the phenomenon of partly defoliation or total one of the individuals, oftenly during the full season of vegetation.
