Light conditions in submountain beech stands in dependence on cutting intensity

Abstract

In 2001-2002 we ran a research on. light intensity on three individual research plots (RP) at the BEES Kremnické vrchy Mts, representing environment of submountain beech, stands. Our study followed with, measurements realised by Střelec in year 1990 in the same stands and under the same conditions. For all partial plots, our measurements confirmed the light intensity peaks presence during midday hours. The absolute maxima representing 56 klx were recorded on open plot between 12.00-14.00 h in time of full developed foliage. On the other hand, the lowest values - 0.022 klx. were obtained for the former plot with clear cut at 06.00 h, in period of full foliage. In period of full leafing, higher values were observed on the open and control plot, on the other hand, in period without foliage, higher values were recorded on the other plots.
