Pollen Viability of Picea obovata Ledeb. under Technogenic Stress Conditions.

The pollen viability of Siberian spruce (Picea obovata Ledeb.) has been studied on the border of the city Krasnoyarsk, as well as under unpolluted growth conditions. This study has discovered the variability and correlation between the functional characteristics of pollens, as well as a low rate of development anomalies. The viability of pollen growth in forest ecosystems of the middle mountains of the Eastern Sayans (the northeastern border of the Krasnoyarskie Stolby national park) have decreased under pollution press. The great variety of pollen viability characteristics of the Siberian spruce pollen makes the high degree of flexibility and adaptability of species reproductive processes evident.
