Anotace	The young even-aged plantation of Norway spruce was divided into two experimental plots differing in their stand density in 1995. In 2001 next cultivating high-type of thinning of 15% intensity in a reduction of stocking density was performed. Total aboveground biomass and its increment were obtained on the basis of stand inventory. The dynamic of LAI development showed a tendency to be saturated, i.e. the LAI value close to 11 seems to be maximal for the local conditions of the investigated plots. Remarkable stimuli (up to 17%) of LAI formation were started in 2002, i.e. as an immediate response to realized thinning. The data set of absorbed PAR and produced biomass in the period 1998–2003 were processed by the linear regression of Monteith’s model, which provided the values of the coefficient of solar energy conversion efficiency into biomass formation (ε). The differences in ε values between the dense and sparse plot after realized thinning amounted to 18%.
