Visual Grading and Quality of 1-O Northern Red Oak Seedlings
Past resebrch has used detailed measureme$s of various growth characteristics to determine seedling grades and quality of northern red oak nursery stock This study evaluates the effectiveness ofa visual grading process. similar + thosefound in commercial nursery operations, to distinguish high quality seedlings. Northern red oak (QuercJs rubra L.) seedlings were grown for I yr at two state nurs...
متن کاملEffects of Visual Grading on Northern Red Oak (Quercus rubra L.) Seedlings Planted in Two Shelterwood Stands on the Cumberland Plateau of Tennessee, USA
Artificial regeneration of oak has been generally unsuccessful in maintaining the oak component in productive upland forests of eastern North America. We tested visual grading effects on quality-grown northern red oak (Quercus rubra) seedlings planted in two submesic stands on the Cumberland Plateau escarpment of Tennessee, USA. Seedlings were grown for one year using advanced fertilization and...
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 کاملUrban environment of New York City promotes growth in northern red oak seedlings.
Urbanization is accelerating across the globe, elevating the importance of studying urban ecology. Urban environments exhibit several factors affecting plant growth and function, including high temperatures (particularly at night), CO(2) concentrations and atmospheric nitrogen deposition. We investigated the effects of urban environments on growth in Quercus rubra L. seedlings. We grew seedling...
متن کاملDo chestnut, northern red, and white oak germinant seedlings respond similarly to light treatments? II. Gas exchange and chlorophyll responses
Understanding differences in physiological and growth strategies in low-light environments among upland oak species may help managers address the challenges of oaks’ poor regeneration. Gas exchange and chlorophyll content were measured for northern red oak (Quercus rubra L.), chestnut oak (Quercus prinus L.), and white oak (Quercus alba L.) germinants grown at 25%, 18%, and 6% of full sun in on...
