Epicormic Branching in Red Oak Crop Trees Five Years after Thinning
INTRODUCTION Epicormic branches are shoots arising spontaneously from adventitious or dormant buds on stems or branches of woody plants, often following exposure to increased light levels or fire (Helms 1998). Epicormic branches are considered defects on tree boles because they result in undesirable knots on trees, reducing the monetary value of logs and lumber (Stubbs 1986). U.S. Department of...
متن کاملCarbon partitioning and allocation in northern red oak seedlings and mature trees in response to ozone.
Northern red oak (Quercus rubra L.) seedlings and trees differ in their response to ozone. Previous work reported reductions in net photosynthesis, carboxylation efficiency and quantum yield of mature tree leaves, whereas seedling processes were unaffected by the same ozone exposure. To further characterize differences in ozone response between seedlings and mature trees, we examined carbon par...
متن کاملEvapotranspiration changes of reference Crop during the growth stages of apple tree in Urmia and Semirom cities
The evapotranspiration of the reference Crop is of particular importance due to the changes in climate parameters of temperature, sunlight, humidity and wind speed in combination. the purpose of this study is to investigate the effects of climate change on evapotranspiration of apple during the growing season.For this purpose, the ECMWF database has been used for observation data of Semirom ...
متن کاملThe Use of Tree Shelters with Northern Red Oak Natural Regeneration in Southern New England
he use of tree shelters with naturally established red oak seedlings was studied in southern New England mixedhardwood stands where deer browsing limited regeneration height growth. Seedlings of three size classes (basal diameters of 5 mm, 8 mm, and 15 mm) were cut off just above ground level during the dormant season to induce sprouting. Plastic tree shelters were placed over one group in each...
متن کاملOak mortality risk factors and mortality estimation
Managers are often concerned about oak mortality in maturing mixed-oak forests, but they often lack explicit information about mortality risk for oaks that differ in species, size, crown class, competitive status, and growth rate. In eastern North America, tree species in the red oak group (Quercus Section Lobatae) are typically shorter lived than those in the white oak group (Section Quercus),...
