Abstrakt
Experimental series at Polička I and Polička II were founded in forest region 16 – the Českomoravská vrchovina Mts. in 1964 in 53-year old Norway spruce stands as the parts of the fourth group of thinning series. The first series Polička I consists of two comparative plots with dimensions 50 m x 50 m, i. e. 0.25 ha each. Comparative plots 1k are control plots without designed thinning and comparative plots 2ú are the stands with thinning by positive selection from above. The second series Polička II consists of three comparative plots of the same dimensions. Except of control plot, it consists of two plots (3p and 5p) with thinning by negative selection from below. Presented paper is oriented on evaluation of basal area development, diameter structure and static stability of investigated stands during the 40-year period of observation.
