摘要

Astract-For the first time for the Central Caucasus, a description of the qualitative parameters of the Scots pine, such as viability and anomalies of pollen grains, is given. The cytological analysis of the morphological damage to the pollen structure enabled us to distinguish six morphotypes of the cells in the study area. At the sites of survey, the occurrence of abnormal pollen grains varied insignificantly and comprised less than 10, except for the Elbrus sample (17). A correlation between abnormal changes in the pollen of the Scots pine and the elevation of its habitat was revealed. In the natural stands of the Scots pine studied, we registered the potentially high quality of the pollen; no correlation between qualitative parameters of the pollen of the Scots pine and the altitudinal gradient was revealed (r = 0.11 when p = 0.005).
