Temporal changes in the proanthocyanidins to anthocyanins ratio during dormancy associate with bloom time variations in peach

open access: yesCurrent Plant Biology
Our previous research demonstrated that fall applications of ethephon, an ethylene-releasing plant growth regulator, delay bloom in peach, accompanied by changes in endogenous hormones, ROS, sugar metabolism, and transcriptomic profiles during bud ...

Comparative Proteomics of Potato Cultivars with a Variable Dormancy Period

open access: yesMolecules, 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 ...

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

open access: yesJournal 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

Hormonal Orchestration of Bud Dormancy Cycle in Deciduous Woody Perennials

open access: yesFrontiers in Plant Science, 2019
Woody perennials enter seasonal dormancy to avoid unfavorable environmental conditions. Plant hormones are the critical mediators regulating this complex process, which is subject to the influence of many internal and external factors.

Daylength effects on black spruce bud dormancy release change during endo- and ecodormancy

open access: yesFrontiers in Forests and Global Change, 2023
The effects of daylength on bud dormancy release varied throughout the dormant period in black spruce (Picea mariana (Mill.) B.S.P.) seedlings.

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

open access: yesAgronomy 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.

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

open access: yesGlobal 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 ...

Dormant Flower Buds Actively Accumulate Starch over Winter in Sweet Cherry

open access: yesFrontiers in Plant Science, 2018
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
