Abstract

The results of pollen quality studies of 18 species of 37-year-old pines done in the pinetum of the Staropetrivske Forestry within the State Enterprise “Kyiv Forest Research Station” are presented. From the 29 planted species of the Pinus genus, only 20 have survived. All species of pine trees represented in the pinetum, “blossom”. The climatic conditions of the region contribute to viable pollen forming (65.9–99.8 %) with a small amount of abnormal pollen grains.

In germinating of pollen abnormalities were detected, namely two pollen tubes in almost all species of pine. The viability of pollen of introduced species of pine and the growth rate of pollen tubes are interconnected. Pollen quality is not a limiting factor for the development of high-quality seeds.

In the pinetum of the State Enterprise “Kyiv Forest Research Station”, introduced pine trees “blossom” successfully, but they do not form a sufficient number of full-grain seeds.
