Increasing Chilling Reduces Heat Requirement for Floral Budbreak in Peach [PDF]

HortScience, 2011
Response to chilling temperatures is a critical factor in the suitability of peach [Prunus persica (L.) Batsch] cultivars to moderate climates such as in the southeastern United States. Time of bloom depends on the innate chilling requirement of the cultivar as well as the timing and duration of cold and warm temperatures experienced by the buds.

Assessment of influence of soil texture and salinity in pecan orchards of southern New Mexico and western Texas

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Pecans [Carya illinoinensis (Wangenh.) K. Koch] are a significant cash crop in the southwest of the United States, and soil properties, irrigation quality, and nutrient availability influence their production. This study was conducted in six orchards along the Rio Grande River in southern New Mexico and southwest Texas during the 2015 and 2016

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.

Shifts in leaf color during ontogeny do not affect herbivory in the tropical tree Lecythis pisonis (Lecythidaceae)

Plant Species Biology, Volume 40, Issue 5, Page 500-509, September 2025.
Leaf color has been rarely evaluated as an important trait influencing herbivory levels in tropical plant species. Cannonball trees (Lecythis pisonis) present pink young leaves that are smaller, softer and with less chlorophyll that progressively turn into green as the season progresses. When all three leaf colors are present in the plants, there is no

Hydrogen Cyanamide-induced Budbreak and Phytotoxicity in `Redhaven' Peach Buds [PDF]

HortScience, 1992
The effects of hydrogen cyanamide (H2CN2) on budbreak and phytotoxicity of l-year-old potted peach trees [Prunus persica (L.) Batsch. cv. Redhaven] over a wide range of concentrations at several stages of dormancy were studied. Endodormancy (180° GS; degree growth stage) began on 1 Oct.

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.

Interactive Effects of Light and Chilling on Peach Flower and Leaf Budbreak [PDF]

HortScience, 2011
Timing of budbreak in response to winter chilling is a critical factor in the suitability of peach [Prunus persica (L.) Batsch] cultivars to moderate climates such as that in the southeastern United States. Much of the research on chilling and dormancy has used excised cuttings or potted trees exposed to various treatments and forced under controlled ...

Gene Regulatory Changes Associated With Phenological Transitions in an Ecologically Significant Tree Species

Plant-Environment Interactions, Volume 6, Issue 4, August 2025.
Climate change is driving earlier spring leaf‐out across temperate regions, but the genetic mechanisms and environmental interactions underlying this variability are poorly understood. We conducted a controlled growth chamber experiment using excised northern red oak (Quercus rubra) branches, testing the influence of temperature and photoperiod on leaf

Seasonal and regional variation in budbreak and flowering of kiwifruit vines in New Zealand [PDF]

New Zealand Journal of Crop and Horticultural Science, 1994
Abstract Measurements of the timing and amount of budbreak and flowering in ‘Hayward’ kiwifruit were made over 4 years in six regions of New Zealand. There was a large variation in the vine attributes measured. The number of flowers produced/winter bud varied 5‐fold between the worst site‐year combination and the best.

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 ...
