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 کاملCytogenetic Characteristics of Weeping Birch (Betula pendula Roth) Seed Progeny in Different Ecological Conditions
The present study of cytogenetic characteristics in seed progeny of woody plants in stress and no-stress conditions is important for better arrangement of green spaces in cities and reforestation on anthropogenically polluted territories because it allows to select maternal trees producing seeds resistant to stress factors. The following cytogenetic characteristics of the root meristematic cell...
متن کاملTemperature dependency of bark photosynthesis in beech (Fagus sylvatica L.) and birch (Betula pendula Roth.) trees.
Temperature dependencies of stem dark respiration (R(d)) and light-driven bark photosynthesis (A(max)) of two temperate tree species (Fagus sylvatica and Betula pendula) were investigated to estimate their probable influence on stem carbon balance. Stem R(d) was found to increase exponentially with increasing temperatures, whereas A(max) levelled off or decreased at the highest temperatures cho...
متن کاملHormesis and Paradoxical Effects of Drooping Birch (Betula pendula Roth) Parameters Under Motor Traffic Pollution
Various plant indexes are used or recommended for bioindication. However, the nonmonotonic dose-response dependences (hormesis and paradoxical effects) of these indexes are insufficiently explored upon exposure to pollution. We studied the dependences of these Betula pendula indexes on the intensity of motor traffic pollution. Regression analysis did not reveal any dependence of chlorophyll and...
