The paper presents the results of leaf- and bud-biomass production for beech stands on plots with original stand density of various grades (0.3, 0.5, 0.7, 0.9). The plots resulted from cutting of various intensity by shelterwood cutting methods which represent the most wide-spread and typical way of natural regeneration. It follows from our results that the production of leaf dry-matter of the tested sample trees of the parent stand increased with increasing cutting intensity. It is true about each crown-third in the case of the codominant and subdominant trees. For dominant trees, the production dependence on stand density was proven only within the lower crown third. The production of buds was found to be distinctly dependent on cutting in the case of subdominant sample trees only. The production of the individual stands, calculated per 1 ha, decreased with increasing cutting intensity. This means that the opposite trend was found in the sample trees.
