Age- and size-related changes in physiological characteristics and chemical composition of Acer pseudoplatanus and Fraxinus excelsior trees.
Forest growth is an important factor both economically and ecologically, and it follows a predictable trend with age. Generally, growth accelerates as canopies develop in young forests and declines substantially soon after maximum leaf area is attained. The causes of this decline are multiple and may be linked to age- or size-related processes, or both. Our objective was to determine the relati...
متن کاملcomparison of lead uptake by four seedling species (acer cappadocicum, fraxinus excelsior, thuja orientalis and cupressus arizonica)
the phytoremediation capability in pb removal from the contaminated soils by three native seedlings species (acer cappadocicum, fraxinus excelsior and thuja orientalis) and one exotic species (cupressus arizonica) were compared. the seedlings were grown in pb contaminated soils at 0, 100, 200, 300, 400 and 500 mg kg-1 concentrations for 6 months (mar 21 to sept. 22, 2015), after which the bioma...
متن کاملCharacterization, localization, and seasonal changes of the sucrose transporter FeSUT1 in the phloem of Fraxinus excelsior
Trees are generally assumed to be symplastic phloem loaders. A typical feature for most wooden species is an open minor vein structure with symplastic connections between mesophyll cells and phloem cells, which allow sucrose to move cell-to-cell through the plasmodesmata into the phloem. Fraxinus excelsior (Oleaceae) also translocates raffinose family oligosaccharides in addition to sucrose. Su...

متن کاملlanguage learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
