The experimental data of model tree from temporal plots in the Northern Steppe of Ukraine were analyzed. The indexes of the average basic density of wood, bark and wood in the bark trunks of black locust trees were determined. The statistical analysis is carried out and the main biometric characteristic and the investigated indicators of the law of normality distribution was analyzed. In the course of statistical analysis, it was determined that the basic wood density and basic wood in the bark with tree age, diameter and height has direct correlation, and basic bark density – inverse correlation. The mathematical models for the estimation of the average basic density of the components of phytomasis of black locust trunks were proposed.
