Relationships of climate change and tree ring of Betula ermanii
Based on the tree-ring growth characteristics of Erman’s birch (Betula ermanii charm.) and the relationships between it and climatic factors at elevation of 1950m, the sensitivity of tree lines in Changbai Mountain to climatic factors was assessed. The results indicated tree line forest in Changbai Mountain had an obvious sensitivity to climate factors. However, difference from other study sits...
متن کاملPhenotypic variation and leaf fluctuating asymmetry in isolated populations of an endangered dwarf birch Betula ovalifolia in Hokkaido, Japan
Betula ovalifolia is an endangered tetraploid that is restricted to two isolated sites, Betsukai and Sarabetsu, in Hokkaido, Japan. Among 50 ramets sampled along transect(s) in the each site, 45 genets in Betsukai and 49 in Sarabetsu were discriminated by simple sequence repeat (SSR) phenotypes. Multivariate patterns in seven measurements for leaf morphology and frequency distributions of fragm...
متن کاملDevelopment and evaluation of microsatellite markers for the critically endangered birch Betula chichibuensis (Betulaceae)1
PREMISE OF THE STUDY Microsatellite markers were developed and characterized for the critically endangered birch Betula chichibuensis (Betulaceae) to investigate the genetic structure of this species for conservation purposes. METHODS AND RESULTS Sixteen microsatellite markers with di-, tri-, and tetranucleotide repeat motifs were developed and optimized using MiSeq paired-end sequencing. Of ...
متن کاملGenetic transformation of silver birch (Betula pendula) by particle bombardment.
We used in vitro callus and shoot cultures as target material for genetic transformation of silver birch (Betula pendula Roth) by particle bombardment. Cultivation of in vitro shoot cultures before particle bombardment and a long selection period, combined with a high concentration of selective agent after bombardment, led to the production of transformed plantlets that were stable, and no esca...
