Специфічна трансформація тканин репродуктивних органів томатів (Lycopersicon esculentum Mill.) під впливом патогенних мікроорганізмів
Aims. The aim of our research was the study of transformation of tissues and cells of reproductive organs of tomatoes (Lycopersicon esculentum Mill.) in conditions of bakteriozis. Methods. For research we have chosen such kinds of tomatoes as “Zarnica”, “Myaghkaya”, “Nasten’ka”, “San’ka”, “Ephemer”, “Novichok”. Structural and functional reorganization in seeds and fruit buds we study using light and fluorescent microscopy methods. Anatomo histological studies of tissues we made according to standard statements. Results. We found that bacterial pathogenesis of tomatoes lead to the destruction in chloroplasts, nucleus and in other components. Under the impact of bacterium’s exometabolites in parenchyma of cover tissues of integuments, placenta and mesocarp of fruits form a viscous consistency secret - polysaccharide, which cause significant disturbance of protoplasts, induces the creation of cell walls, leads to chlorotic changes which are followed by necrosis of tissues. Conclusions. We suggested the transformations of tissues and cells of reproductive organs of tomatoes in conditions of bakteriozis divide into 6 main stages.
Key words: Lycopersicon esculentum Mill., cells components, bakteriozis.
