The essential oil of Betula pendula Roth. buds was obtained using both hydrodistillation and microdistillation techniques and their chemical compositions were analyzed using both gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Overall, more than 50 compounds were identified representing 80% and 92% for hydrodistillation and microdistillation, respectively. The main com...

The research presents the first results of aluminium speciation analysis in aqueous extracts of individual plant parts of Betula pendula and soil samples, using High Performance Ion Chromatography with Diode Array Detection (HPIC-DAD). The applied method allowed us to carry out a full speciation analysis of aluminium in the form of predominant aluminium-fluoride complexes: AlF(x=2,3,4)(3-x) (fi...

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...

South rear-edge populations of widely distributed temperate and boreal tree species such as birches (Betula pubescens Betula pendula) are considered particularly vulnerable to climate warming, at the same time, they constitute genetic reservoirs drought-adapted ecotypes. Here, we compared radial growth patterns responses climate, river, or reservoir flows a drought index (southernmost) (Toledo ...

Tree seedling flooding tolerance for 22 species was assessed under controlled field condi­ tions. Initial heights under control (freely draining soil, n = 20 per species) and flooded (stand­ ing water, depth = 10 cm, n = 20 per species) conditions were measured in March 1990. Sur­ vival, height and diameter growth were determined after 120 days. Recovery from flooding effects was assessed in th...
