Zubrovska O. Lipids and cuticles secondary metabolites of trees foliage in the adaptation reactions under the actions of heavy metals.

It was investigated in the thesis features of physiological adaptation of different trees under the influence of industrial pollution containing excess heavy metals which is implemented via the intensity of lipid peroxidation, activity of lipase and change the components composition of the surface layer of the cuticle of foliage. It was established species-specific accumulation of heavy metals in the foliage of plants on various stages of morphogenesis. Experimental species were divided into three groups according to level of accumulation of zinc, nickel, lead and cadmium. It was found that compatible impacts of heavy metals induce the development of free radical reactions which is accompanied in increasing the level of primary peroxidation products and TBA-active compounds. It was revealed for the first time the variability of the composition and neoplasm’s / degradation of certain components of the surface layer of the cuticle which significantly affect the hydrophobicity and permeability of the cuticle and provide stability trees to pollution. It was shown for the first time the changes in the composition terpenoids.
