Vliv zástinu na přírůst obnovy borovice lesní pod porostem / Canopy effect on the Scotch pine regeneration in understory

The Pinus sylvestris natural regeneration growth and site characteristics effect were evaluated in the area of VLS ČR, s. p. divize Mimoň-Doksy in september of 2015. The dendrometric parameters of seedlings as listed: the total height, the diameter, the last 5 years height increment, the crown diameter, the quality and vitality of plants and the branch angle) were measured at nine plots. Also microsite characteristics, such as: herbal layer composition, light conditions, litter horizons and distance to the nearest adult tree) were noted at these sites. The 416 seedlings were measured in total. The main site characteristic with significant effect on the mean increment was direct photosynthetical radiation (r = 0,47). Other significat factors were the total and the diffuse photosynthetical radiation, the canopy and the amount of small bushes in herbal layer. There can be also concluded that good light conditions have statistically significant effect on the quality of seedlings. Influence of other site characteristics was not statistically significant.
