Effect of Ecological Factors on the Accumulation of Fluorine by Larches, Larix gmelinii (Rupr.) Rupr. and L. sibirica Ledeb., in Eastern Siberia

The accumulation of fluorine in the trunk wood and branches of Larix gmelinii growing on soils with a naturally increased fluoride content and of L. sibirica growing in a zone affected by atmospheric emissions from an aluminum plant has been studied. Based on results of in vivo and in vitro experiments, it is concluded that larch trees manifest individual differences in their response to fluorine.[PUBLICATION ABSTRACT]
