Essential Oil of Betula pendula Roth. Buds
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...
متن کاملPhysiological responses of Betula pendula Roth growing in polluted areas
Plant functioning is affected by drought, extreme temperatures, heavy metal pollution and other unfavorable environmental conditions. High intensity of stress factors can be lethal to sensitive organisms or significantly decrease their condition. Intensification of stress factors is observed especially in urban and industrial areas. During the vegetative season plants purify the air and soil, d...

متن کاملImpacts of elevated atmospheric CO2 and O3 on paper birch (Betula papyrifera): reproductive fitness.
Atmospheric CO2 and tropospheric O3 are rising in many regions of the world. Little is known about how these two commonly co-occurring gases will affect reproductive fitness of important forest tree species. Here, we report on the long-term effects of CO2 and O3 for paper birch seedlings exposed for nearly their entire life history at the Aspen FACE (Free Air Carbon Dioxide Enrichment) site in ...
متن کاملEffects of aluminium on the growth and mineral composition of Betula pendula Roth.
Aluminium (Al) is rhizotoxic and is often present in acidic soils at activities high enough to inhibit root elongation. The objectives of the present study were to assess the level of Al tolerance in different races of Betula pendula Roth (Silver Birch) and to investigate how growth and nutrient acquisition were affected by Al. A solution culture technique was employed which simulated natural s...
