Modelling individual tree diameter growth for Norway spruce in the Czech Republic using a generalized algebraic difference approach
base-age invariant approach Chapman-Richards function global parameters tree-specific parameters iterative nested regression National Forest Inventory
2017/6/26
Individual tree-based growth models precisely describe the growth of individual trees irrespective of stand complexity. These models are more useful than the stand-based growth models for effective ma...
Evaluation of the genetic diversity of selected Fagus sylvatica L. populations in the Czech Republic using nuclear microsatellites
DNA analysis European beech populations gene reserves genetic distance
2017/4/6
Fagus sylvatica Linnaeus (European beech), the ecologically and economically most important broadleaved tree species in the Czech Republic, was strongly reduced in the past. Today there are efforts to...
Comparison of growth development of micropropagated and generatively reproduced wild cherry (Prunus avium (L.) L.) on the Polná demonstration plot (Czech Republic) up to the age of 15 years
forest trees vegetative propagation in vitro clone testing field trials
2016/6/3
Four clonal progenies of wild cherry obtained using an in vitro technique and control progeny of generative origin were tested on the Polná research plot in southeastern Bohemia. Growth characteristic...
Use of nuclear microsatellite loci for evaluating genetic diversity among selected populations of Abies alba Mill. in the Czech Republic
simple sequence repeats silver fir populations genetic variability and differentiation genetic distance gene reserves DNA analysis
2015/8/27
The simple sequence repeats (SSR) method of DNA analysis was used to determine genetic diversity within and among silver fir (Abies alba Mill.) populations. Total genomic DNA was extracted from 250 Ab...
Sawflies (Hymenoptera: Symphyta) in the northeast of the Czech Republic with special regard to spruce forests
Malaise trap faunistics host plants abundance
2015/5/6
Sawflies were collected in the northeast of the Czech Republic using Townes type Malaise traps. Traps were placed in eleven young Norway spruce (Picea abies) forests during the period from 1998 to 199...

clonal test linear mixed models spatial analysis
2015/3/6
A 6-year-old clonal trial with 13 clones of wild cherry (Prunus avium L.) was evaluated during the summer of 2004 at 6 different sites in the Czech Republic. Observed traits were the stem height, stem...
