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

Near-surface remote sensing of spatial and temporal variation in canopy phenology [PDF]
, 2009 There is a need to document how plant phenology is responding to global change factors, particularly warming trends. “Near-surface” remote sensing, using radiometric instruments or imaging sensors, has great potential to improve phenological monitoring ...

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 ...

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

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 ...
