Abstract

The results are presented long-term (2005–2015) observations of the seed progeny condition of the Scots pine populations in the Gomel region. The purpose of the work is to study the influence of climatic factors on Scots pine seed material formation under permanent radiation exposure. It found that weather conditions exert a much higherimpact on the quality of seed progeny than radiation exposure, and the seeds formed under conditions of chronic irradiation characterized by a high level of interannual variability of viability indicators in the remote period after the Chernobyl accident.
