Annotation The present study investigates the issue of morphological differences in cone and seed structure of Pinus sylvestris L. (Pinaceae) gathered in different natural habitat parts. The aim of the study was to determine distinguishing characteristics of P. sylvestris grown near the city of Chita and P. sylvestris grown on the territory of Tsasuchey pine forest (Transbaikal Territory). L. P. Sergievskaya, E. N. Kondratyuk considered P. Krylovii Serg. et Kondr species to be the main breed of Tsasuchey pine forest, and it differed from P. sylvestris by bigger cones and anatomical needle structure. L. F. Pravdin thought that these two species have considerable differences connected with the cone and seed structure. P. Krylovii is not considered to be a separate species in the latest works. The study of biometric parameters of the female cones and seeds of P. sylvestris grown near the city of Chita and on the territory of Tsasuchey pine forest provides evidence that they have some considerable distinguishing morphological characteristics. They are the following: P. sylvestris cone weight grown in Tsasuchey pine forest is 82 % more, the mass of 1000 seeds is 57 % more, they also have a 63 % increase in the seed thickness, 70 % of cones have f.reflexa-shaped apophysis.
