   <abstract xml:lang="ru">
    <p>Исследованы реакции на озон поверхностных клеток листьев c голубой или серебристой окраской у растительных видов: василисника малого Thalictrum minus L, лоха колючего Elaeagnus pungens Thunb., ивы белой Salix alba L., облепихи крушиновидной Hippophae rhamnoides L., красного клевера Trifolium pratense L., клевера ползучего Trifolium repens L, райграса пастбищного Lolium perenne Engels. У них не отмечено заметных спектральных изменений. Показано, что поверхностные слои кутикулы и клеточной стенки этих растений содержали азулены. В спектрах поглощения листьев отмечены характерные для этих синих пигментов максимумы соответственно 580-585 нм и 608-610 нм, а в спектрах флуоресценции – 410 или 430-450 нм. Предполагается, что именно эти пигменты могут быть первичными мишенями для озона у видов с синей или серебристой окраской листьев, и их антиоксидантные свойства определяют низкую чувствительность к озону.  В этом случае синие пигменты служат защитным оптическим фильтром от ультрафиолетовой радиации и озона, образуемого с ее участием.</p>

    <p>Reactions to ozone of surface cells of leaves with blue or silver color in plant species: meadow-rue Thalictrum minus L., oleaster Elaeagnus L., white willow Salix alba L., buckthorn Hippophae rhamnoides L., creeping clover Trifolium repens L, red clover Trifolium pretense L., ryegrass pasture Lolium perenne Engels were studied. They had no noticeable spectral changes. It has shown that the surface layers of the cuticle and the cell wall of these plants contained azulenes. In the leaf absorption spectra, the maxima characteristic of these blue pigments of 580-585 nm and 608-610 nm, respectively, were noted, and in the fluorescence spectra – 410 or 430 nm. It has assumed that these pigments may be the primary targets for ozone in species with blue or silvery leaf color, and their antioxidant properties determine low sensitivity to ozone.  In this case, the blue pigments serve as a protective optical filter against ultraviolet radiation and ozone formed with its participation.</p>
