Site influence on anatomical structure of bald cypress

The paper deals with length of tracheids of bald cypress at two alluvial sites in Serbia. Scope of the paper was to establish site inf luence (climate, soil, etc.) on mentioned anatomical feature and to quantify it, as well. Axial tracheid changes have been observed depending on three factors: cambial age, zone inside growth ring and stem height where sampling was performed. The paper established gradually increasing of axial tracheid length with cambial age and that did not depend on zone inside growth ring and stem height. There was also significant inf luence of the zone inside growth ring to axial tracheid length, while stem height where sampling was performed does not have significant inf luence. There was found relation between factors that determine site such as physical and chemical soil properties and climate from one and axial tracheid length from another side.
