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.

Transcriptional evidence of pluripotency during development of the leaf gall formed by grape phylloxera (Daktulosphaira vitifoliae)

New Phytologist, Volume 247, Issue 4, Page 1712-1726, August 2025.
Summary Galls are structures formed by plants in response to stimuli by parasitic insects. Because galls require altered gene expression to change cell fates, their initiation requires pluripotent or ‘reactive’ cells. We used RNA sequencing to test three hypotheses about potential sources of pluripotency in the leaf gall formed by grape phylloxera ...

Evaluation of the budbreak timing in walnut cultivars and breeding forms among the Kuban germplasm, and validation of the trait-related SSR-markers

Труды по прикладной ботанике, генетике и селекции
Background. Walnut (Juglans regia L.) is the most widespread species within the genus Juglans. Late spring frosts can significantly reduce its yield.

Genomic resources for crop wild relatives are critical for perennial fruit breeding and conservation

American Journal of Botany, Volume 112, Issue 7, July 2025.
Abstract Many perennial fruit crops are clonally propagated, resulting in uniform fruit quality but increasing vulnerability to pests, diseases, and climate change. In contrast, closely related crop wild relatives (CWRs) continue to evolve in response to these pressures and are a valuable source of adaptive traits.

Changes of Membrane Lipids in Apple Buds During Dormancy and Budbreak [PDF]

Journal of the American Society for Horticultural Science, 1990
The changes of membrane lipids in apple (Malus domestics Borkh. cv. Delicious) auxillary and terminal buds from August to April were determined. The predominant lipids were monogalactosyl diglyceride (MGDG), digalactosyl diglyceride (DGDG), phosphatidylcholine (PC), and phosphatidylethanolamine (PE).

Understanding Flower Frost Tolerance in Almond (Prunus dulcis): The Role of Phenology, Cultivar and Sugars Content

Journal of Agronomy and Crop Science, Volume 211, Issue 4, July 2025.
ABSTRACT Freezing temperatures during the flower and fruitlet stages are considered one of the most limiting factors for almond cultivation. Understanding the minimum temperature that reproductive organs can resist without damage is crucial for adapting the crop to different environmental conditions and for breeding cultivars with enhanced tolerance to

Determinants of the Southern Range Limit of an Infamous North American Forest Defoliator

Journal of Biogeography, Volume 52, Issue 7, July 2025.
ABSTRACT Aim Predicting climate driven species range shifts requires knowledge of mechanisms limiting species fitness under various climatic conditions. The traditional approach of modelling ranges of herbivorous insects by fitting environmental niche models to occurrence records is generally incapable of differentiating direct effects of climate on ...

Uncertainties in predicting the medium-term future occurrence of grapevine budburst in Europe: the role of phenological models and climate scenarios

OENO One
Budbreak plays an important role in the grapevine growing cycle and temperature is its main driver. Therefore, phenological models use two temperature-based approaches to simulate budbreak: a chilling-forcing scheme, which describes either endo- and eco-

Antecipação da colheita de caqui 'Costata' através da quebra de dormência com cianamida hidrogenada e óleo mineral Persimmon 'Costata' harvest advancement after dormancy breakdown by hydrogen cyanamide and mineral oil application

Revista Brasileira de Fruticultura, 2004
No município de Araponga, Estado de Minas Gerais, foi estudada a possibilidade de antecipar a colheita do caquizeiro 'Costata', e obter preços mais elevados no mercado através da quebra de dormência artificial. A cianamida hidrogenada nas doses de 2,4; 7,
