Timeline of Leaf and Cambial Phenology in Relation to Development of Initial Conduits in Xylem and Phloem in Three Coexisting Sub-Mediterranean Deciduous Tree Species [PDF]

open access: yesForests, 2020
It is unclear how the anticipated climate change will affect the timing of phenology of different tree organs/tissues and thus the whole-tree functioning. We examined the timing of leaf phenology and secondary growth in three coexisting deciduous tree species (Quercus pubescens Willd., Fraxinus ornus L.

A Coupled Model of Hydraulic Eco-Physiology and Cambial Growth - Accounting for Biophysical Limitations and Phenology Improves Stem Diameter Prediction at High Temporal Resolution. [PDF]

open access: yesPlant Cell Environ
ABSTRACTTraditional photosynthesis‐driven growth models have considerable uncertainties in predicting tree growth under changing climates, partially because sink activities are directly affected by the environment but not adequately addressed in growth modelling. Therefore, we developed a semi‐mechanistic model coupling stomatal optimality, temperature

Tonoplast sucrose transporter SUT4-dependent sugar partitioning modulates phenological transitions and reproductive success in poplar. [PDF]

open access: yesPlant J
Significance Statement This field study demonstrates that the loss of SUT4, the most highly expressed sucrose transporter during cool seasons, disrupts phenology, growth, and fertility in poplar. Altered sugar and raffinose dynamics in the mutants, along with dysregulated stress and circadian clock genes, underscore SUT4's role in coordinating sugar ...

Radial growing, cambial activity, and phenology of tree species in a subtropical forest in Southern Brazil

open access: yesiForest - Biogeosciences and Forestry
Understanding the factors that affect cambial activity can provide historical documentation of events influencing plant growth and development. This study aimed to link cambial activity and diameter increment of native and exotic species in a floodplain ...

Cambial Activity and Phenology in Three Understory Species along an Altitude Gradient in Mexico [PDF]

open access: yesForests, 2021
The aims of this study were to evaluate the cambial activity and phenology of three species with different life forms (Alchemilla procumbens, Acaena elongata and Ribes ciliatum) along an altitudinal gradient and to establish which environmental variables (light, soil humidity and temperature) had the greatest influence on cambial activity and ...

Variation in Onset of Leaf Unfolding and Wood Formation in a Central African Tropical Tree Species

open access: yesFrontiers in Forests and Global Change, 2021
A diversity of phenological strategies has been reported for tropical tree species. Defoliation and seasonal dormancy of cambial activity inform us on how trees cope with water stress during the dry season, or maximize the use of resources during the ...

Response of model-based cambium phenology and climatic factors to tree growth in the Altai Mountains, Central Asia

open access: yesEcological Indicators, 2022
It is important to study the relationships between tree growth and phenology and climate factors in Central Asia for the sustainable development of forest ecology and the exploration of carbon sink potential in the region in a context of global change ...

Cambial growth season of brevi-deciduous Brachystegia spiciformis trees from south central Africa restricted to less than four months. [PDF]

open access: yesPLoS ONE, 2012
We investigate cambial growth periodicity in Brachystegia spiciformis, a dominant tree species in the seasonally dry miombo woodland of southern Africa. To better understand how the brevi-deciduous (experiencing a short, drought-induced leaf fall period)

Carbon and oxygen isotope fractionations in tree rings reveal interactions between cambial phenology and seasonal climate [PDF]

open access: yesPlant, Cell & Environment, 2018
AbstractWe developed novel approaches for using the isotope composition of tree‐ring subdivisions to study seasonal dynamics in tree–climate relations. Across a 30‐year time series, the δ13C and δ18O values of the earlywood (EW) cellulose in the annual rings of Pinus ponderosa reflected relatively high intrinsic water‐use efficiencies and high ...

Environmental Drivers for Cambial Reactivation of Qilian Junipers (Juniperus przewalskii) in a Semi-Arid Region of Northwestern China

open access: yesAtmosphere, 2020
Although cambial reactivation is considered to be strongly dependent on temperature, the importance of water availability at the onset of xylogenesis in semi-arid regions still lacks sufficient evidences.
