Deciphering cork formation in Quercus suber
The family of Fagaceae, comprises about 900 species, among them the best-known group of this family is the oaks, genus Quercus, that are commonly used as timber or for cork production. Cork is produced by Q. suber, an evergreen oak with major economic and environmental importance for Mediterranean region, in particular for Portugal that is the leading producer of this material. Besides, the eco...
متن کاملPhylogeographical variation of chloroplast DNA in cork oak (Quercus suber).
BACKGROUND AND AIMS In the last decades, the geographical location of the centre of origin of Quercus suber (cork oak), a strictly western Mediterranean oak species, has been the subject of controversy. METHODS RFLP variation over the whole chloroplast DNA molecule and PCR-RFLPs over seven specific cpDNA fragments were analysed phylogeographically to reconstruct the evolutionary history of co...
متن کاملQuercus nigra and Quercus alba
lnvestigaltons into the nature of desiccation-sensitive, or recalcitant, seed behavior have as yet failed to identify exact causes of this phenomenon. Experiments with Quercus nigra L. and Quercus alba L. were conducted to examine physiological and biochemical changes brought about by seed desiccation and to determine if there were predictable changes in seed moisture content, m enthalpy (heat ...
متن کاملDrought-induced photosynthetic inhibition and autumn recovery in two Mediterranean oak species (Quercus ilex and Quercus suber).
Responses of leaf water relations and photosynthesis to summer drought and autumn rewetting were studied in two evergreen Mediterranean oak species, Quercus ilex spp. rotundifolia and Quercus suber. The predawn leaf water potential (Ψ(lPD)), stomatal conductance (gs) and photosynthetic rate (A) at ambient conditions were measured seasonally over a 3-year period. We also measured the photosynthe...
متن کاملEffects of abiotic and anthropogenic factors on the spatial distribution of Quercus faginea
11 12 Species distribution is usually explained by abiotic factors, particularly, climatic variables which 13 are often considered as the most important drivers of species distribution. Nevertheless, when 14 investigating the underlying causality in species distribution, the importance of those factors 15 together with the role of anthropogenic factors (land-use variables) must be considered. 1...
