Divergence in leaf and cambium phenologies among three temperate tree species of different wood types with special reference to xylem hydraulics [PDF]
Leaf and cambium phenologies are both important aspects of tree environmental adaptation in temperate areas. Temperate tree species with non-porous, diffuse-porous and ring-porous woods diverge substantially in the strategy of coping with freezing ...

Xylogenesis and phloemogenesis in the flesh of sweet cherry fruit are limited to early-stage development [PDF]
Water inflows into sweet cherry fruit occur via the xylem and the phloem vasculatures of the pedicel. The rates of these inflows are subject to marked changes during fruit development.

Wood, derived from plant secondary growth, is a commercially important material. Both cellulose and lignin assembly have been well studied during wood formation (xylogenesis), but heteroxylan biosynthesis is less well defined.

Asynchronous and correlations of radial growth between different lateral meristems in Abies forrestii var. smithii [PDF]
Understanding radial growth phenology is crucial in the comprehension of tree physiology and its susceptibility to climate change. Numerous studies have investigated the impacts of radial growth activity in stem meristems and environmental factors on ...

Tree Growth Under Climate Change: Evidence From Xylogenesis Timings and Kinetics [PDF]
Tree growth is one of the most studied aspects of tree biology, particularly secondary growth. In the Mediterranean region, cambial activity is mostly determined by water availability.

Long-Term Cambial Phenology Reveals Diverging Growth Responses of Two Tree Species in a Mixed Forest Under Climate Change. [PDF]
We 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]
Rapid 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 ...

Age‐dependent xylogenesis in timberline conifers [PDF]
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
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.

On growth and flow: hydraulic aspects of aboveground meristems. [PDF]
Summary 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,
