Quercus 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 کاملRegeneration Patterns of European Oak Species (Quercus petraea (Matt.) Liebl., Quercus robur L.) in Dependence of Environment and Neighborhood
Quercus robur L. (pedunculate oak) and Quercus petraea (Matt.) Liebl. (sessile oak) are two European oak species of great economic and ecological importance. Even though both oaks have wide ecological amplitudes of suitable growing conditions, forests dominated by oaks often fail to regenerate naturally. The regeneration performance of both oak species is assumed to be subject to a variety of v...
متن کاملHow Discrete Are Oak Species? Insights from a Hybrid Zone between Quercus Grisea and Quercus Gambelii.
The white oaks Quercus gambelii and Q. grisea overlap in distribution in New Mexico and Arizona. Within the region of overlap, there are numerous instances of contact between the two taxa. In some areas of contact morphologically, intermediate trees are common, whereas in others, morphologically intermediate trees are rare or absent. We describe a set of RAPD markers that distinguish between th...
متن کاملAcquisition of Ophiostoma quercus and Ceratocystis fagacearum by Nitidulids from O. quercus–Colonized Oak Wilt Mats
Oak wilt infection centers are initiated by overland spread of the causal fungus, Ceratocystis fagacearum (T. W. Bretz) J. Hunt, by insects (10). Sap-feeding beetles (Coleoptera: Nitidulidae) are considered a primary vector of the pathogen in the north central states (7,9). Successful transmission by sap-feeding beetles depends on several coexisting conditions, including (i) the availability of...
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...
