How 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 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 کاملVariable Budbreak and Insect Folivory of Gambel Oak (Quercus gambelii: Fagaceae)
Budbreak of individual ramets of clonal Gambel oak (Quercus gambelii: Fagaceae) was advanced experimentally to test the effects of altered timing of budbreak and hence, leaf age, on patterns of folivory. Early-season folivory by leaf-chewing insects was significantly greater on younger leaves of control ramets than older leaves of experimental ramets. However, differences in cumulative folivory...
متن کاملPhysiological and biochemical responses of Quercus brantii seedlings to water deficit stress
Water shortage is one of the most important environmental stresses in Mediterranean regions. Poor seedling quality may account for the failure of oak regeneration. To determine the best seed origin of Quercus brantii, we investigated on seedlings collected from 20 mother trees in the Zagros Mountain forests 700 to 2200 m altitudes above sea level. Seedlings from different altitudes were irrig...
متن کاملGrowth Characteristics of Ectomycorrhizal Seedlings of Quercus glauca, Quercus salicina, Quercus myrsinaefolia, and Castanopsis cuspidata Planted in Calcareous Soil
To verify the acclimation capacity of evergreen Fagaceae species on calcareous soil, we compared ecophysiological traits between Quercus glauca Thunb., Q. salicina Blume, Q. myrsinaefolia Blume, and Castanopsis cuspidata (Thunb.) Schottky as typical woody species from southwestern Japan. We also examined the inoculation effects of the ectomycorrhizal (ECM) fungi Astraeus hygrometricus and Scler...
