Genetic 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 کاملEssential 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 کاملElevation of night-time temperature increases terpenoid emissions from Betula pendula and Populus tremula
Volatile organic compounds (VOCs) are expected to have an important role in plant adaptation to high temperatures. The impacts of increasing night-time temperature on daytime terpenoid emissions and related gene expression in silver birch (Betula pendula) and European aspen (Populus tremula) clones were studied. The plants were grown under five different night-time temperatures (6, 10, 14, 18, ...
متن کاملجداسازی و شناسایی قارچهای همراه بذر درختان توس (Betula pendula, Betula litwinowii) در جنگلهای شمال کشور
توس (Birch) از درختان مهم جنگلهای شمال کشور است که در معرض انقراض قرار دارد. زادآوری طبیعی این گونهی با ارزش، به دلیل وجود عوامل محدود کننده ازجمله آفات و عوامل بیماری‌زا؛ به‌ویژه قارچها، با مشکلات فراوانی مواجه است. به‌منظور جداسازی و شناسایی قارچهای همراه بذر توس، بذرهای گونه pendula Betula از جنگلهای سیامرزکوه استان گلستان و بذرهای گونه Betula litwinowiiاز سنگده اس...
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...
