Do Nonstructural Carbohydrates Contribute to Pecan (Carya illinoinensis) Secondary Budburst?
HortScience, 2023 Spring freeze is among the problems threatening pecan bloom and production. Pecan tree height and structure make them difficult to protect from spring freezes. Some cultivars can compensate because the secondary buds can produce healthy flowers if the primary buds freeze. The mechanism that precipitates secondary budbreak is unknown. Our results show a

Analysis of grapevine phenology in the region of Sremski Karlovci [PDF]
Journal of Agricultural Sciences (Belgrade), 2013 A comprehensive analysis of phenological timing and growth intervals for eight red and thirteen white wine grape cultivars in the region of Sremski Karlovci was performed using a long-term (1986-2011) data set.

Insufficient Chilling Effects Vary among Boreal Tree Species and Chilling Duration
Frontiers in Plant Science, 2017 Insufficient chilling resulting from rising winter temperatures associated with climate warming has been an area of particular interest in boreal and temperate regions where a period of cool temperatures in fall and winter is required to break plant ...

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 ...

Forecasting bark beetle early flight activity with plant phenology [PDF]
, 2016 Bark beetle outbreaks are a major threat to forest productivity, and a robust forecast of early flight activity is necessary for inhibition or mitigation of large-scale infestations.

Trends and uncertainties in budburst projections of Norway spruce in Northern Europe [PDF]
Ecology and Evolution, 2017 AbstractBudburst is regulated by temperature conditions, and a warming climate is associated with earlier budburst. A range of phenology models has been developed to assess climate change effects, and they tend to produce different results. This is mainly caused by different model representations of tree physiology processes, selection of observational

The variable effect of polyploidization on the phenotype in Escallonia [PDF]
, 2018 To induce new variation within the Escallonia genus, chromosome doubling was performed in E. rubra, E. rosea, and E. illinita, three important species within this genus of mainly evergreen woody ornamental species.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Frontiers in Plant Science, 2015 Many temperate and boreal tree species have a chilling requirement, that is, they need to experience cold temperatures during fall and winter to burst bud normally in the spring. Results from trials with 11 Pacific Northwest tree species are consistent
