Dinâmica da dormência de gemas de dois anos de macieira 'Imperial Gala' em região de baixa ocorrência de frio Dormancy dynamics of two year old buds of 'Imperial Gala' apple tree in a region of low chill occurence

Revista Brasileira de Fruticultura, 2004
O objetivo deste trabalho foi determinar a dinâmica da dormência de gemas em ramos de dois anos de macieira 'Imperial Gala' com ou sem frio suplementar durante o outono e inverno, cultivadas em Porto Amazonas - PR, região de baixa ocorrência de frio.

The performance of growing degree day models to predict spring phenology of herbaceous species depends on the species' temporal niche

Functional Ecology, Volume 40, Issue 5, Page 1207-1220, May 2026.
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

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

Functional Ecology, Volume 40, Issue 5, Page 1251-1269, May 2026.
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.

Bud dormancy evolution in apple genotypes with contrasting chilling requirements

Revista Brasileira de Fruticultura, 2022
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.

Frost induced changes in enzyme activities and carbohydrate content in the spurs of some pear cultivars during the dormancy

International Journal of Horticultural Science, 2008
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 ...

Chilling of Endodormant Peach Propagules: I. Seed Germination and Emergence [PDF]

Journal of the American Society for Horticultural Science, 1993
We compared peach [Prunus persica (L.) Batsch cv. Johnson Elberta] seed germination (G) and seedling emergence (E) after various stratification (St) treatments. Treatments were arranged in factorial combinations of five St durations (20 to 60 days) at eight constant temperatures (0 to 18C) in

Summer‐dormant, perennial groundcover has minimal effect on plant‐available nutrients and no effect on maize yield

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
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.

Is GABA-shunt functional in endodormant grapevine buds under respiratory stress?

Plant Growth Regulation, 2013
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

Comparative Proteomics of Potato Cultivars with a Variable Dormancy Period

Molecules, 2022
The control of the duration of the dormancy phase is a significant challenge in the potato industry and for seed producers. However, the proteome landscape involved in the regulation of the length of the dormancy period over potato cultivars remains ...

Rethinking Model Transferability: Validity Domains as a New Approach to Delineate the Limits of Bloom Date Projections

Global Change Biology, Volume 32, Issue 3, March 2026.
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 ...
