With the use of “Arbotom®”, an acoustic ultrasound tomography complex, the evaluation of the state of trunk wood tissue of trees C. torulosa, C. arizonica, C. sempervirens var. stricta and C. macrocarpa has shown that these species are characterized by a significant differentiation in the pore fungi damage degree. A low rate of phytogenic damage is observed in C. torulosa. The trunk wood tissues of C. marcocarpa are characterized by the highest rates of phytopathogenic degradation. It has been specified that the species in vegetative phase are the most vulnerable to the adverse effect of pore fungi. The negative impact of pore fungi is one of the most significant factors decreasing the vegetative functions and limiting the longevity of Cupressus genus' species under the conditions of the southern coast of the Crimea (SCC). The phytopathogenic damage of wood tissue and the formation of trunk tissue rot have an effect on the implementation of the bioenvironmental program of growth and development of a plant, reducing the time scale of passing certain ontogenesis stages.
