Morphobiological foundations of the development of resisting ornamental crops

The article discusses alternative ways of protecting ornamental plants from stress factors of a biotic nature by increasing passive immunity when using environmentally friendly unconventional fertilizers as the main source of macro- and microelements and biologically active substances that differ in adaptogenic and immunomodulatory properties. The aim of the study was to assess the effect of a complex of biologically active substances and non-traditional fertilizers on the development of resisting of ornamental plants. The objects of the study were ornamental plants of the genus Rose, Tulipa and Gladíolus , which were used in landscaping urban ecosystems when creating landscape compositions. Sewage sludge (SS) of the municipal unitary industrial enterprise of the water supply and sewerage economy "Orelvodokanal", buckwheat family of LLC "Elita", vermicompost obtained on the basis of SS, buckwheat family and ash using earthworms from the Lumbricidae family were used as unconventional fertilizers. The study of the changes in the anatomical and morphological features of plants Rosa L., Tulipa L. and Gladiolus L. as a result of the influence of biologically active substances and non-traditional fertilizers was carried out using a biological microscope "Biolam S-13". The paper shows the change in the anatomical, morphological, physiological characteristics of ornamental plants in anthropogenic and cultural landscapes, which determines their ecological resistance to stress factors and harmful objects. The integration of environmentally friendly components in the cultivation of ornamental plants contributed to an increase in the thickness of the epidermis of Rosa L. leaves by 1.5 times; Tulipa L. - 1.4; Gladiolus L. - 1.6 times; leaf mesophyll thickness 1.9; 1.4; 1.6 times, respectively; leaf thickness of Rosa L. and Gladiolus L. plants by 1.2 times; Tulipa L. - 1.7 times. There is a significant increase in the osmotic pressure of Tulipa L. and Gladiolus L. plant cells by 26.8 and 28.3 kPa. Weak stomatal opening was noted in experimental variants Tulipa L. and Gladiolus L., as well as highly resistant cultivars Rosa L.
