Bezak: I´ARAMhTRI SPIRANCKVIH DRVNOGROMADNIH TABLICA ZA KRUPNO DRVO HRASTA Šumarski list br. 11 12, CXXV (2001), 635-640 The arithmetic mean of the form factor of model trees of sessile oak is 0,51987, and the value ranges from 0.42743 to 0.54132. Volume parameters of usable timber (above 7 cm) of common beech: d20500706 v= 0.000026285 h´M"m The arithmetic mean of the form factor of model trees of common beech is 0,51507, and the value ranges from 0.40506 to 0.53061. The paper highlights the need for further research, the justification of testing two-parameter volume tables with a special stress on management methods and the change of form factor. Key words: pedunculate oak (Quercus robur L.), sessile oak (Quercus petraea L.), common beech (Fagus sylvatica L.), two-parameter volume tables, usable timber PRETPLATA ZA ŠUMARSKI LIST U 2002.
