Under climate warming, earlier spring phenology has heightened the risk of late spring frost (LSF) damage. However, the intricate interplay among LSF, spring phenology and photosynthetic carbon uptake remains poorly understood. Using 286,000 ground phenological records involving 870 tree species and remote-sensing data across the Northern Hemispher...

Late spring frosts, occurring after spring phenological events, pose a dire threat to tree growth and forest productivity. With climate warming, earlier spring phenological events have become increasingly common and led to plants experiencing more frequent and severe frost damage. However, the effect of late spring frosts after leaf-out on subseque...

Lammas growth of trees means the additional growth of the shoot after the growth cessation and bud set in late summer. In temperate tree species, lammas growth occurs irregularly and is often regarded as abnormal, disturbed growth. In subtropical tree species, however, lammas growth is a prevalent phenomenon, possibly due to the prolonged occurrenc...
Article
Physiological seed drop is a recognized phenomenon in economic forest, caused by the abscission of developing seeds due to intergroup competition for resources. However, little is known about the resource allocation dynamics in species exhibiting a biennial fruiting cycle, where interactions occur not only among seeds of the same year but also betw...

In studies of plant spring phenology, temperature sum models are traditional tools. They are used to quantify plant development in terms of accumulation of temperature-dependent developmental units, such as Growing Degree Hours, GDHs. A key parameter in these models is the threshold (or base) temperature, Tthr, representing the lower thermal limit...
Article
Winter rest and chilling accumulation play a crucial role in regulating the leaf-out and flowering of extratropical woody plants. Still, there is a lack of understanding regarding the potential rest condition of overwintered immature cones of coniferous trees and how the dormancy of different organ types responds to environmental cues. To address t...

Global warming has generally advanced the spring phenology of extratropical trees. In several cases, however, the advancing has levelled off, indicating a declining temperature sensitivity of phenological timing. The potential reasons for the decline have been actively debated, but no direct experimental evidence has been produced to support any of...
Article
Climatic warming is currently changing the spring phenology of extratropical trees, and this has several important effects on the trees and ecosystems. The major climatic cues regulating the spring phenology are winter chilling, spring forcing, and photoperiod. The interactions between these three remain largely unstudied because most studies conce...

Studies 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 in...
Article
Full-text available
Bud dormancy of plants has traditionally been explained either by physiological growth arresting conditions in the bud, or by unfavourable environmental conditions, such as non‐growth‐promoting low air temperatures. This conceptual dichotomy has provided the framework also for developing process‐based plant phenology models. Here we propose a novel...
