Frost Tolerance of Black Spruce Seedlings (Picea Mariana) during Budbreak [PDF]

HortScience, 1995
Spring frosts frequently cause significant damage to conifer seedlings during bud flushing and shoot elongation in forestry nurseries. To ensure adequate protection, levels of frost sensitivity must be known during these stages of development. Eight-month-old, containerized, black spruce seedlings were submitted to freezing temperatures of 0, –4, –6 ...

Multivariate models improve accuracy of genomic prediction for spring frost tolerance in Norway spruce

The Plant Genome, Volume 18, Issue 4, December 2025.
Abstract Warming spring temperatures increase the risk of frost damage to emerging Norway spruce (Picea abies) buds by advancing their spring phenology and increasing the frost event frequency. We present a field‐based electrolyte leakage assay to assess basal frost tolerance in newly emerging buds. Using this assay, we estimated genetic parameters and

Candidate genes associated with bud dormancy release in blackcurrant (Ribes nigrum L.)

BMC Plant Biology, 2010
Background The detrimental effects of mild winter temperatures on the consistency of cropping of blackcurrant (Ribes nigrum L.) in parts of Europe have led to increasing interest in the genetic control of dormancy release in this species.

National‐scale terrestrial biodiversity and ecosystem monitoring with essential biodiversity variables in Japan and Finland

Ecological Research, Volume 40, Issue 6, November 2025.
Essential Biodiversity Variables (EBVs) provide a standardized framework for monitoring biodiversity change in line with conservation targets. We assessed terrestrial biodiversity datasets for EBVs in Japan and Finland, and compared Japan's data availability with GEO BON and EuropaBON, identifying both unique strengths and gaps.

Effect of four formulations on the dormancy release of dormant buds and the subsequent development of shoots under typical vineyard conditions

Notulae Botanicae Horti Agrobotanici Cluj-Napoca
One of the key challenges of sustainable viticulture under climate change is the insufficient chilling necessary for dormancy release, leading to uneven budbreak and reduced productivity.

Can Fine‐Root Non‐Structural Carbohydrates Explain Seasonal Variations in the Respiration in Subalpine Forests?

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Fine root respiration drives root growth and resource acquisition in cold, nutrient‐poor ecosystems, yet its association with root phenology remains unclear. Non‐structural carbohydrates (NSC), stored as soluble sugars and starch are primary metabolites that play key roles in physiological functions.

Tonoplast sucrose transporter SUT4‐dependent sugar partitioning modulates phenological transitions and reproductive success in poplar

The Plant Journal, Volume 124, Issue 4, November 2025.
Significance Statement This field study demonstrates that the loss of SUT4, the most highly expressed sucrose transporter during cool seasons, disrupts phenology, growth, and fertility in poplar. Altered sugar and raffinose dynamics in the mutants, along with dysregulated stress and circadian clock genes, underscore SUT4's role in coordinating sugar ...

Chilling requirement of Ribes cultivars

Frontiers in Plant Science, 2015
It is usually thought that adequate winter chill is required for the full flowering of many temperate woody species. This paper investigates the sensitivity of blackcurrant bud burst and flowering to natural weather fluctuations in a temperate maritime ...

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.

Chilling and Budbreak in Lingonberries, Vaccinium vitis-idaea L.1

Journal of the American Society for Horticultural Science, 1983
Abstract Three seedling populations of lingonberries from Fairbanks, Alaska, Oulu, Finland, and the Pasvik River Valley, Norway were exposed to 0, 170, 344, 513, 681, 843, 1013, and 1185 hours of continuous chilling temperatures (4 ± 1°C) to determine chilling requirements necessary to satisfy rest.
