Nucleus–nucleolus characteristics of Pinus brutia var. stankewiczii Sukacz. seeds were analyzed under conditions of the marginal part of the area and recreational load. Interpopulation polymorphism in the number of nucleoli and their size was detected in the cells of P. brutia var. stankewiczii seedlings from the southeastern coast of Crimea. For a population experiencing recreational load, an increase in the average area of nucleoli in the nucleus and a decrease in nucleus–nucleolus ratio was n
