The paper deals with height and density of woody rays per mm2 by bald cypress stems at two alluvial sites in Serbia (Veliko ratno ostrvo and Backa Palanka). Overall 6 stems (3 at one and 3 at another locality) were harvested. After that discs were made and they served for permanent anatomical preparations making. All necessary measurements were performed on these preparations. Inside each growth ring was selected 6 visible fields (3 at early- and 3 at latewood zone) and within all fields density of woody rays per mm2 was calculated. According to simple equation number of woody rays per mm2 was determined. As for height of woody rays, it was calculated by parenchyma cells counting. Researched bald cypress features were measured depending on 3 factors: cambial age, stem height and zone inside growth ring. As for relation between number and height of woody rays, there is obvious inverse - greater density of woody rays means they are shorter. The scope of the paper was to establish how height and number of woody rays per mm2 change depending on 3 observed factors - age, stem height and zone inside growth rings.
