Micropropagated Silver Birches (Betula pendula) in the Field – Performance and Clonal Differences
Micropropagated and seed-born silver birches (Betula pendula Roth) were compared for survival, height growth and occurrence of biotic damage (voles, hares, mooses, stem lesions and cankers) in fi eld trials in southern Finland. The material consisted of 11 clones and 10 different lots of seedlings growing in 10 fi eld trials, established in clearcut forest cultivation areas. The plants were 6–7...
متن کاملElevated air humidity affects hydraulic traits and tree size but not biomass allocation in young silver birches (Betula pendula)
As changes in air temperature, precipitation, and air humidity are expected in the coming decades, studies on the impact of these environmental shifts on plant growth and functioning are of major importance. Greatly understudied aspects of climate change include consequences of increasing air humidity on forest ecosystems, predicted for high latitudes. The main objective of this study was to fi...

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...
متن کاملExpression of senescence-associated genes in the leaves of silver birch (Betula pendula).
Development was monitored throughout the entire life span of silver birch (Betula pendula Roth.) leaves. The focus was on senescence-related changes in photosynthesis and gene expression. The youngest fully developed leaves were compared with older senescing leaves in two silver birch lines: the wild-type line R and a late-senescing line R3.1. Line R3.1 was found among transgenic lines produced...
