Long-Term Cambial Phenology Reveals Diverging Growth Responses of Two Tree Species in a Mixed Forest Under Climate Change. [PDF]
Glob Chang BiolWe studied how climate change affects tree growth by monitoring wood formation in Scots pine (Pinus sylvestris) and Pyrenean oak (Quercus pyrenaica) over 11 years. We found that warmer winters lead to earlier growth onset in pines, while oaks are more influenced by soil moisture. Hot and dry summers shortened growth in both species, but oaks maintained

Phenological Shifts in Wood Formation Tracked by Frost Rings Across Two Centuries. [PDF]
Glob Chang BiolRapid warming is reshaping plant phenology across ecosystems. We present an indirect retrospective approach to infer cambial phenology by analysing the timing and occurrence of frost rings in three Alpine conifers. We found that the cold spells responsible for frost ring formation typically involve temperature dropping below freezing for an average of ...

On growth and flow: hydraulic aspects of aboveground meristems. [PDF]
New PhytolSummary Water is essential for plant growth under both normal and stress conditions. Aboveground, two key meristems control plant development: the shoot apical meristem and the vascular cambium. Here, stem cell maintenance and cell differentiation are affected by hydraulic fluctuations across seasons, days, or even hours. Water fluxes, turgor pressure,

Age‐dependent xylogenesis in timberline conifers [PDF]
New Phytologist, 2007 Neither anatomical change nor physiological abnormalities have been observed in the cambia of older trees. However, different sensitivity and period of significant responses to climate suggest the existence of some age-related change in the patterns of cambial activity and/or wood cell formation. Here, weekly cambial activity and timing and duration of

Xylogenesis is uncoupled from forest productivity
Trees, 2021 Pinus leiophylla production of radially enlarging tracheids is bimodal with peaks in June and October. The production of thickening tracheids and NDVI were coupled. In drought-prone areas, xylem production and forest productivity are assumed to depend on the amount and timing of precipitation.

Transcriptomic Analysis of Multipurpose Timber Yielding Tree Neolamarckia cadamba during Xylogenesis Using RNA-Seq. [PDF]
PLoS ONE, 2016 Neolamarckia cadamba is a fast-growing tropical hardwood tree that is used extensively for plywood and pulp production, light furniture fabrication, building materials, and as a raw material for the preparation of certain indigenous medicines.

Differences in xylogenesis between dominant and suppressed trees [PDF]
American Journal of Botany, 2018 AbstractPremise of The StudyMost dendroecological studies focus on dominant trees, but little is known about the growing season of trees belonging to different size classes and their sensitivity to biotic factors. The objective of this study was to compare the dynamics of xylem formation between dominant and suppressed trees of Abies fabri of similar ...

Plastic bimodal xylogenesis in conifers from continental Mediterranean climates [PDF]
New Phytologist, 2009 *Seasonal radial-increment and xylogenesis data can help to elucidate how climate modulates wood formation in conifers. Few xylogenesis studies have assessed how plastic xylogenesis is in sympatric conifer species from continental Mediterranean areas, where low winter temperatures and summer drought constrain growth.

BMC Plant Biology, 2018 Background Adventitious roots (ARs) are often necessary for plant survival, and essential for successful micropropagation. In Arabidopsis thaliana dark-grown seedlings AR-formation occurs from the hypocotyl and is enhanced by application of indole-3 ...

Frontiers in Plant Science, 2016 Mediterranean tree rings are characterized by Intra-Annual Density Fluctuations (IADFs) due to partly climate-driven cambial activity. IADFs are used as structural signals to gain information on relations between environmental conditions and eco ...
