abstract east azarbaijan province is one of the most important areas for poplar production and has the highest suitability of poplar plantation in iran. three species of poplar trees included populus alba, p. nigra and p. x. euramericana are planted and usually attacked by different pests in this province. melasoma populi l., archips rosana (l.) and pemphigus filaginis are some of important pes...

Complete Populus genome sequences are available for the nucleus (P. trichocarpa; section Tacamahaca) and for chloroplasts (seven species), but not for mitochondria. Here, we provide the complete genome sequences of the chloroplast and the mitochondrion for the clones P. tremula W52 and P. tremula x P. alba 717-1B4 (section Populus). The organization of the chloroplast genomes of both Populus cl...

Populus alba Villafranca clone was chosen for a proof of concept study to determine the potential uptake and accumulation of antibiotics by trees. Plants were grown hydroponically and irrigated with a recirculating Hoagland's nutrient solution (control) and Hoagland's nutrient solution fortified with erythromycin at 0.01, 0.1 and 1mgL(-1). After 3 and 28days of treatment, poplar plants were sep...

Intersectional crosses between species of sections Aigeiros (Populus deltoides, P. X euramericana or P. nigra) and Leuce (P. alba or P. tremuloides) are known to be reciprocally incompatible. The site of pollen tube arrest is on the stigma surface in pollinations between pistils of section Leuce and pollen of section Aigeiros; tubes failed to penetrate the stigma surface. In reciprocal matings,...

metal pollution has become one of the most serious environmental problems resulting from human activity. phytoremediation utilizes plants to uptake contaminants and can potentially be used to remediate metal-contaminated sites. the present study investigates heavy metal uptake (cd, cr, and ni) from soil by different organs of populus alba and morus alba. for this purpose, cd (40, 80, and 160 m...
