Abstract.The plantings state study in conditions of a high degree of the environment urbanization is of undoubted interest from the point of view of the development of scientifically based methods of work on the care of plantings and maintaining their decorativeness. Currently, there are a number of techniques that allow us to assess the condition of plants by visual (morphological) parameters. However, morphological indicators do not always fully characterize the plant condition which has a damage inside the trunk. The aim of the work was to identify the relationship between visual indicators of the plantings condition and the instrumental assessment results. Instrumental diagnostics of wood was carried out using an «Arbotom» acoustic ultrasound tomograph. The paper presents the old-age plantings of berry apple(Malus baccata (L.) Borkh.) morphological assessment results on the territory of the Petrovsko-Razumovskoye estate (Moscow), which is an object of cultural heritage of the Russian Federation. Studies using ultrasound tomography on apple tree culture are not described in the literature. A comprehensive study, including visual and instrumental analysis of the plantings condition was carried out for the first time. The study showed that all objects have extensive development of core and core-sapwood rot in the internal structure of trunks in the absence of external signs of destruction. The authors emphasize that a reliable assessment of the trees vital condition should be carried out comprehensively using a visual and instrumental method, this will provide an opportunity to carry out timely measures to support the plantings condition in order to avoid emergency situations.
