Gross nitrogen retranslocation within a canopy of Quercus serrata saplings.
Nitrogen (N) retranslocation within tree canopies has been intensively studied and assumed to function as a one-way process (e.g., from older to newer leaves). However, recent studies have found that both N output and input occur in individual leaves, suggesting that 'gross' N retranslocation exists behind 'net' N retranslocation. In the present study, the amount and direction of gross N retran...
متن کاملCharacterizing fertility targets and multi-element interactions in nursery culture of Quercus rubra seedlings
We quantified and characterized fertility targets for nursery culture of container northern red oak (Quercus rubra L.) seedlings. Plants were supplied with a 15N-5P2O5-15K2O fertilizer at eight rates ranging from 0–150 mg N plant–1 and reared for 18 wk in a greenhouse. Plant growth and nutritional response to increased fertilization followed a curvilinear pattern depicting phases that ranged fr...
متن کاملGrowth, gas exchange, and root respiration of Quercus rubra seedlings exposed to low root zone temperatures in solution culture
Spring planting is standard operational practice in the Central Hardwood Region, though little is known about potential impacts of low root temperature (RT) common during spring on establishment success of temperate deciduous forest tree species. The effects of low RT on growth, gas exchange, and root respiration following winter dormancy were studied in 1-year-old northern red oak (Quercus rub...
متن کاملHay-scented fern (Dennstaedtia punctilobula (Michx.) Moore) interference with growth of northern red oak (Quercus rubra L.) seedlings.
We assessed the impacts of hay-scented fern (Dennstaedtia punctilobula (Michx.) Moore) and subsoil liming (CaO amendments) on root and shoot growth of greenhouse-grown, first-year, northern red oak (Quercus rubra L.) seedlings. Red oak seedlings and ferns were grown in reconstructed soil profiles of four common Pennsylvanian forest soils. When grown in the presence of hay-scented ferns, with or...
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...
