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...
Production impacts of forest tree breeding on an example of Norway spruce
economic efficiency forest tree breeding growth Norway spruce production
2015/3/19
The present paper evaluates the height, diameter and stem volume of parental tree progenies. These Norway spruce progenies are compared with the control estimated from tables. The control was overperf...
Polyamines during somatic embryo development in Norway spruce (Picea abies [L.])
Norway spruce somatic embryogenesis putrescine
2015/3/16
Contents of free polyamines (putrescine, spermidine and spermine) were determined in different developmental stages of Norway spruce (Picea abies [L.] Karst.) somatic embryos by means of HPLC. Determi...
Tolerance of Norway spruce (Picea abies [L.] Karst.) embryogenic tissue to penicillin, carbapenem and aminoglycoside antibiotics
aminoglycoside antibiotics Norway spruce Agrobacterium tumefaciens
2015/3/16
Somatic embryogenesis is conveniently utilized for the preparation of Norway spruce (Picea abies [L.] Karst.) transgenic clones by means of Agrobacterium. The establishment of successful transformatio...
Differential success of somatic embryogenesis in random gene pool of Norway spruce
Norway spruce somatic embryogenesis Picea abies
2015/3/6
Somatic embryogenic cultures were established from proembryonal suspensor masses (PEMs) derived from mature seeds of Norway spruce. In this study we used more than 4,300 seeds of Picea abies from rand...

2015/3/5
Tree-level allometric functions for a precise predicting of stem, branch and leaf mass and surface area of three needle-shoot age classes were estimated from measurements of crown and stem dimensions ...
Structural diversity change and regeneration processes of the Norway spruce natural forest in Babia hora NNR in relation to altitude
Norway spruce virgin forest
2015/3/3
The research was focused on exploring the dynamics and forms of regeneration processes and structural
diversity of the Norway spruce virgin forest in Babia hora NNR in relation to altitude. In each ...
