Des tarifs de cubage globaux et des équations volumes à diamètre longueur variables ont été ajustés l’aide d’un système d’équations simultanées pour le chêne zéen (Quercus canariensis Willd.), en Tunisie. Les données utilisées proviennent 75 arbres échantillonnés dans la forêt localisée région d’Ain Sallem au Nord-Ouest du pays. La méthode d’ajustement adoptée est celle régression non linéaire ...

The genus Coolia A. Meunier 1919 has a global distribution and is common member of epiphytic dinoflagellate assemblages in neritic ecosystems. monotis the type species was only known for 76 years. Over past few decades, molecular characterization unveiled two complexes that group morphologically very similar species, so their limits are often unclear. To provide new knowledge on biogeography co...

Purpose of the study: to study effect oil pollution on morphological parameters cereal grasses: canary grass, timothy grass and meadow fescue. Tasks: assessment impact soils seed germination, growth development studied species by parameters; analysis variability indicators. Oil-contaminated high-moor peat was used as a substrate. Objects research: seeds Phleum pratense L, 1753, fescue Festuca p...

UNLABELLED Red Palm Weevil (RPW, Rhynchophorus ferrugineus Olivier) threatens most palm species worldwide. Until now, no studies have analyzed the gene regulatory networks of Phoenix canariensis (Chabaud) in response to RPW attacks. The aim of this study was to fill this knowledge gap. Providing this basic knowledge is very important to improve its management. RESULTS A deep transcriptome ana...

Article history: Received on: 08/09/2016 Revised on: 09/10/2016 Accepted on: 22/11/2016 Available online: 28/12/2016 Phoenix canariensis is a commonly grown, yet understudied, palm plant. The phytochemical screening of leaves and pollens revealed the presence of flavonoids, saponins, tannins, sterols and/or triterpenes. Quantitative estimation of constituents, revealed that the total polyphenol...
