Progress in the field of evolutionary forest ecology has been hampered by huge challenge phenotyping trees across their ranges natural environments, and limitation high-resolution environmental information. The GenTree Platform contains phenotypic data from 4,959 12 ecologically economically important European tree species: Abies alba Mill. (silver fir), Betula pendula Roth. birch), Fagus sylva...
Late-embryogenesis-abundant proteins (LEA) typically accumulate to high levels during seed dehydration and have an important role in the plant response abiotic stresses. Transgenic hybrid poplars of 9-year-old TaLEA lines showed adaptation drought saline–alkali conditions. The exogenous gene was expressed normally, T-DNA insertion sites were identified on different chromosomes. Improving surviv...
The phenanthrene-degrading activity (PDA) of Pseudomonas putida ATCC 17484 was repressed after incubation with plant root extracts of oat (Avena sativa), osage orange (Maclura pomifera), hybrid willow (Salix alba x matsudana), kou (Cordia subcordata) and milo (Thespesia populnea) and plant root exudates of oat (Avena sativa) and hybrid poplar (Populus deltoides x nigra DN34). Total organic carb...
In the last years the supercritical fluid extraction has been frequently used to obtain volatile oils from aromatic plants. In this work we have applied this technique to a different vegetable matrix: poplar (Populus nigra and MC) buds as it is known that they contain antioxidant compounds. The results of the supercritical extraction have been compared with those of the conventional soxhlet ext...
The flavonoids present in beeswax produced in “La Alcarria” region were analyzed by HPLC. Pinocembrin, pinobanksin, pinobanksin 3-acetate, chrysin, galangin and techtochrysin were detected as the main flavonoid constituents. This is the first detailed report on the flavonoids o f beeswax. These substances are already present when wax scales are secreted by bees. The same flavonoid compounds wer...
Under the present paper, authors have reposted finding of Sambucus nigra L. as new introduction in medicinal plans in the flora of "Valley of flowers'. Sambucus nigra L. Originally is an European plant and is very important for its medicinal potential, being used in various systems of medicine to cure number of ailments. In natural order Sambucus nigra L. belongs to family caprifoliaceae.
*Correspondence: J. Y. Zhu, Forest Products Laboratory, 1 Gifford Pinchot Dr., Madison, WI, USA e-mail: [email protected] Poplar NE222 (Populus deltoides Bartr. ex Marsh×P. nigra L.) wood chips were pretreated in a 390 L pilot-scale rotating wood-pulping digester using a dilute sulfite solution of approximately pH 1.8 at 160°C for 40 min for bioconversion to ethanol and lignosulfonate (LS). An est...
Phytoremediation of heavy metals is employed as a technological approach for a non-destructive remediation of contaminated soils. One of the most recently studied tree species used in phytoremediation applications are poplars. In this study, the one-year old rooted seedlings of Populus nigra L. used to decontaminate hexavalent chromium-contaminated soils. Five treatments of Cr (VI) supply (were...
در این بررسی چوبهای سبز و تازه قطع شده تبریزی (Populus nigra L. var. italica) به روش تیوب لاستیکی اشباع گردیدند. پس از قطع درختان و اندازه بری چوب، بلافاصله فقط سر قطور تیر به طول حدود 15 سانتیمتر پوست کنی شدند. یک سر تیوب لاستیکی در قسمت پوست کنی شده نیز قرار گرفته و با نوار لاستیکی محکم بسته شد. تیرها در حالت شیب دار قرار گرفتند به طوری که سر قطور تیرها حداقل 45 سانتیمتر بالاتر از سر باریک آن...
