We investigated the individual and combined effects of elevated CO2 concentration and fertilization on aboveground growth of three poplar species (Populus alba L. Clone 2AS-11, P. nigra L. Clone Jean Pourtet and P. x euramericana Clone I-214) growing in a short-rotation coppice culture for two growing seasons after coppicing. Free-air carbon dioxide enrichment (FACE) stimulated the number of sh...

Propolis is the substance used by bees as a draught excluder and general purpose sealer for their hives. It usually consists of a mixture of pop­ lar bud exudate and beeswax [1]. Propolis balsam (a 70% alcohol extract of propolis which contains the bud exudate components) is a popular herbal medicine [2-4] containing a number of phenolic constituents with antimicrobial activity [4-6], Bees appe...

Phytoremediation is a promising technology to remediate carcass burial sites where deep soil layers are contaminated with nitrogen (N), phosphorus (P) and other potential contaminants by leachate. The current study was conducted to examine the remedial efficiency of two different woody plants, poplar (Populus euramericana) and willow (Salix alba), by employing the deep-planting technique for th...

The prediction of the modulus elasticity (MOE) five species different spectrum density woods, namely, Populus × euramericana I-214 (Poplar), Fagus sylvatica L. (Beech), Quercus pyrenaica (Oak), Paulownia elongata S.Y.Hu (Paulownia) and Pinus sylvestris (Scots pine) were examined through natural frequency vibration on cantilevered beams (transverse direction) ultrasound (longitudinal direction)....
