STRUCTURAL AND FUNCTIONAL-ORGANIZATION OF ASSIMILATIVE APPARATUS OF ARBORETAL PLANTS IN VIEW OF GAS RESISTANCE

The physiological and anatomical aspects of arboreal plant resistances under industrial air pollution by gaseous nitrogen and sulphur compou nds were studied. Unlike sensitive plants, resistant ones are characte rized by a high activity of reducing the disturbed structure and funct ion, by a high resistance of regulatory cellular systems. Activation o f tile synthesis of proteins, amino acids. pigments, acid-soluble phos phoric compounds, change saturated-unsaturated fatty acids ratio. plas ticity of optic and photosynthetic leaf structures raise the gas resis tance.
