Pollen anomalies of Sukachyov's larch in various ecological conditions

Researches of pollen grains anomalies of Sukachyov larch (Larix sukaczevii Dyl.), growing in various ecological conditions are conducted. The received results reflect the negative influence of technogenic pollution on quality of pollen grains at investigated kind. Comparison of indicators of anomaly/fertilnosti of pollen with use of criterion χ2 testifies that distinctions between the trial areas from contrast ecological conditions are authentic at high significance values. The used cytologic method is very sensitive in an es-timation of adverse factors influence degree at ecosystems of Sukachyov s larch.
