Long-term monitoring of Beech tree growth for quantifying relationships between the occurrence of tension wood, tree motion, and growth stresses
Bech trees is the most abundant broadleaf species in central Europe. The main wood quality problems affecting this species are red heartwood from one hand and growth stresses associated with tension wood on the other hand. Concerning the last point, recent research studies have been carried out during the FAIR project, “Growth stresses in beech”, and completed in 2001. In particular, they focus...
متن کاملTree Growth Visualization
In computer graphics, models describing the fractal branching structure of trees typically exploit the modularity of tree structures. The models are based on local production rules, which are applied iteratively and simultaneously to create a complex branching system. The objective is to generate three-dimensional scenes of often many realisticlooking and non-identical trees. Our goal, instead,...
متن کاملTemperature and tree growth.
Tree growth helps US forests take up 12% of the fossil fuels emitted in the USA (Woodbury et al. 2007), so predicting tree growth for future climates matters. Predicting future climates themselves is uncertain, but climate scientists probably have the most confidence in predictions for temperature. Temperatures are projected to rise by 0.2 °C in the next two decades, then by 1.5–3.5 °C at the e...
متن کاملRegenerative tree growth processes
We introduce regenerative tree growth processes as consistent families of random trees with n labelled leaves, n ≥ 1, with a regenerative property at branch points. We establish necessary and sufficient conditions on the growth rules under which we can apply results by Haas and Miermont to establish self-similar random trees and residual mass processes as scaling limits. This framework includes...
متن کاملAntagonistic Regulation of Arabidopsis Growth by Brassinosteroids and Abiotic Stresses
To withstand ever-changing environmental stresses, plants are equipped with phytohormone-mediated stress resistance mechanisms. Salt stress triggers abscisic acid (ABA) signaling, which enhances stress tolerance at the expense of growth. ABA is thought to inhibit the action of growth-promoting hormones, including brassinosteroids (BRs). However, the regulatory mechanisms that coordinate ABA and...
