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.

CONVERSION OF BOUND TO FREE WATER IN ENDODORMANT APPLE BUDS
Proton Density and T2 maps were created throughout the dormant season in `Anna' and Northern Spy′ apple cultlvars. The percentige of oixels with 15-25 ms T2 time increased from 30% in both cultlvars at the beginning of dormancy to 80 and 72% respectively, by the end of dormancy. The conversion in `Anna' was rapid and in `Northern spy was slow.

Dormant Flower Buds Actively Accumulate Starch over Winter in Sweet Cherry
Temperate woody perennials survive to low temperatures in winter entering a dormant stage. Dormancy is not just a survival strategy, since chilling accumulation is required for proper flowering and arbitrates species adaptation to different latitudes. In

Abstract Conventional agriculture in the US Midwest has accelerated crop productivity but also contributed to undesirable environmental issues. Perennial groundcovers (PGCs), such as cool‐season grasses intercropped in the maize (Zea mays L.) interrow, have the potential to reduce soil erosion rates and mitigate nutrient losses.

Accurately predicting future phenology events in novel environmental conditions is a key challenge in modelling. Using first bloom observations of the Japanese Yoshino cherry across a temperature gradient, we calibrated process‐based and machine learning models at multiple locations and cross‐validated them to obtain the predictive performance for all ...

Photoperiod–Temperature Interactions in a Changing Climate: A Review of Plant Phenological Responses
ABSTRACT Aim Climate change is reshaping plant phenology and species distributions, especially in temperate and boreal ecosystems, where advances in spring events have already extended the growing season. While temperature has been the primary focus of many studies, the role of photoperiod—a stable, latitude‐dependent cue—remains underexplored.

Is GABA-shunt functional in endodormant grapevine buds under respiratory stress?
It has been suggested that a respiratory stress is part of the mechanism through which the dormancy-breaking compounds, hydrogen cyanamide (HC) and sodium azide, induce the release of buds from the endodormancy (ED) in grapevines. The accumulation of metabolites like succinate, alanine (Ala) and γ-amino butyric acid (GABA), together with the activation

Background and Aims Dormancy in grapevines (Vitis vinifera) is a critical adaptive strategy that enables vines to survive harsh winter conditions and is influenced by physiological and environmental factors. This study aimed to investigate the progression of endodormancy across different pruning dates and cultivars and to identify the key ...
