(In)determinacy in Woody Plants: Limits and Opportunities for Timing Growth in a Changing Climate
Tree growth is shaped not only by temperature and water availability, but also by intrinsic developmental programming that constrains when and how long meristems remain active. We use (in)determinacy—the continuum from fixed, preformed seasonal growth to more flexible, ongoing organ production—to predict how species will differ in risk exposure ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract The concept of growing degree days (GDDs) is commonly used to predict phenological events in plants, assuming that plants develop proportionally to the accumulated temperature. Two species‐specific parameters, TBase and t0 (minimum temperature above which and start date

Endodormancy release in Norway spruce grafts representing trees of different ages
AbstractStudies addressing endodormancy release in adult trees are usually carried out using twigs detached from the trees in the experiments. Potential problems caused by cutting the root–shoot connection when detaching the twigs can be avoided by using grafts as the experimental material. We studied the effects of chilling on the endodormancy release

Frost tolerance of pear cultivars was checked after artificial cold treatment in 2003-2005. Limbs collected during the endodormancy were exposed in a climatic chamber for 24 hours to —25; —28 °C, while those collected in the ecodormancy were kept at —15 ...

Bud dormancy evolution in apple genotypes with contrasting chilling requirements
This work evaluates how thermal regimes with constant or oscillating temperatures affect the onset and overcome of endodormancy in apple buds with low (‘Castel Gala’) and high (‘Royal Gala’) chilling requirements.

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Chilling of Endodormant Peach Propagules: II. Initial Seedling Growth [PDF]
We observed initial peach [Prunus persica (L.) Batsch] seedling growth after endodormant (ED) seeds (`Johnson Elberta') had been stratified for five durations (20 to 60 days) at eight constant temperatures (0 to 18C). Seedling growth increased and became more normal when seeds were stratified

Dormancy Patterns of Apple Trees Grown in a Mild Winter Region: A Breakpoint Model Analysis
ABSTRACT Climate change poses a significant challenge to the production of temperate climate fruit trees, since the dormancy of these species is regulated by the chill and heat accumulation during winter and early spring. This study aimed to identify the dormancy evolution patterns of three apple cultivars (“Galaxy,” “Fuji Suprema,” and “Eva”) in a ...

Ice Nucleation and Freezing Consequences in Perennial Plants
ABSTRACT The precise location where ice forms in plants affects the physical constraint it exerts on the different biological compartments (cells, tissues, organs). It is therefore critical to understand where and how ice nucleates to predict the extent of low temperature damage.

Relationship Between Endodormancy and Cold Hardiness in Grapevine Buds
Endodormancy (ED) and cold hardiness (CH) are two strategies utilized by grapevine (Vitis vinifera L.) buds to survive unfavorable winter conditions. Each phenomenon is triggered by different environmental cues—ED by short-day (SD) photoperiod and cold hardiness (CH) by low temperatures.
