Adaptative Strategy of Leaf Traits to Drought Conditions: Quercus aliena var. (bioone.org)
Between-site ITV of leaf traits was primarily driven by canopy structure and climate. (gc.ca)
Comparatively, environmental drivers explained only a small proportion of variability in root traits: these relationships were trait specific and included soil conditions (Root P), canopy structure (Root N) and neighbourhood composition (SRL, Root K). Between-site ITV was associated with increased environmental fit only for a minority of traits, primarily in response to climate (SLA, Leaf N, SRL). (gc.ca)

That all depends on whether tree growth is more limited by the amount of photosynthesis or by the environmental conditions that affect tree cell growth-a fundamental question in tree biology, and one for which the answer wasn't well understood, until now. (utah.edu)
A study led by University of Utah researchers, with an international team of collaborators, finds that tree growth does not seem to be generally limited by photosynthesis but rather by cell growth. (utah.edu)
We learned the basics in elementary school-trees produce their own food through photosynthesis, taking sunlight, carbon dioxide and water and turning it into leaves and wood. (utah.edu)
So trees get carbon from the atmosphere through photosynthesis. (utah.edu)
If the trees' growth is source-limited, then it's limited only by how much photosynthesis the tree can carry out and tree growth would be relatively easy to predict in a mathematical model. (utah.edu)
The researchers analyzed the data they collected, looking for evidence that tree growth and photosynthesis were processes that are linked, or coupled. (utah.edu)
When photosynthesis increased or decreased, there was not a parallel increase or decrease in tree growth. (utah.edu)

Leaf tissue analysis is the quantitative determination of the total mineral nutrient concentrations in the leaf. (ufl.edu)
Leaf analysis is a useful tool to detect problems and adjust fertilizer programs for citrus trees because leaf nutrient concentrations are the most accurate indicator of fruit crop nutritional status. (ufl.edu)
Leaf samples must be taken at the correct time of year because nutrient concentrations within leaves continuously change. (ufl.edu)
