The minimum temperature for budburst in Betula depends on the state of dormancy [PDF]
Tree Physiology, 2012 Vegis has put forward the theory that the range of growth-promoting temperatures changes during the induction and the release of dormancy. We have tested the response of buds of Betula pubescens Ehrh. and B. pendula Roth. on temperature during the induction and release of dormancy. Betula seedlings were exposed to dormancy-inducing high-temperature and

Representing explicit budburst and senescence processes for evergreen conifers in global models [PDF]
Agricultural and Forest Meteorology, 2018 Global ecosystem models lack an explicit representation of budburst and senescence for evergreen conifers despite their primordial role in the carbon cycle. In this study we evaluated eight different budburst models, combining forcing, chilling and photoperiod, for their ability to describe spring budburst, and one model of needle senescence for ...

Spatial and Temporal Trends in the Timing of Budburst for Australian Wine Regions
Australian Journal of Grape and Wine Research, 2022 Background and Aims. This research investigates spatial and temporal trends in budburst timing across Australian wine regions from 1910–2019. The potential drivers of these observed trends were then identified, including anthropogenic climate change and ...

Do Nonstructural Carbohydrates Contribute to Pecan (Carya illinoinensis) Secondary Budburst? [PDF]
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.

Evaluating chemicals for inducing budburst in peach orchard grown in subtropical conditions
Semina: Ciências Agrárias, 2022 The availability of chill hours influences the break dormancy, sprouting and production of temperate fruit trees in different regions. During the winter, the chilling requirements for growing peaches in subtropical locations are restricted, and certain ...

BUDBURST TIMING OF VALLEY OAKS AT HASTINGS RESERVATION, CENTRAL COASTAL CALIFORNIA [PDF]
Madroño, 2021 We studied the timing of budburst of valley oak (Quercus lobata Née) at Hastings Reservation, central coastal California. Similar to other taxa, budburst was advanced by warmer temperatures.

Frost hardening and dehardening potential in temperate trees from winter to budburst [PDF]
New Phytologist, 2017 Summary We investigated how deciduous trees can adjust their freezing resistance in response to temperature during the progress of the ecodormancy phase, from midwinter to budburst. We regularly sampled twigs of four different temperate deciduous tree species from January to the leaf‐out date. Using computer‐controlled freezers and climate chambers,

Bud-break promoters for the improvement of the budburst of pecan cultivars
Pesquisa Agropecuária Brasileira, 2022 The objective of this work was to evaluate the effect of different bud-breaking substances on the budburst of the Barton, Desirable, and Jackson pecan (Carya illinoinensis) cultivars.

Nepalese HorticultureBerry harvesting coinciding with the monsoon is the major problem of grapevine (Vitis vinifera L.) cultivation in Nepal. Nepalese viticulture is benefitted by advancing budburst and hydrogen cyanamide (HC) has the potential to break the bud dormancy in ...

Chilling rather than photoperiod controls budburst for gymnosperm species in subtropical China
Journal of Plant Ecology, 2021 The mechanisms regulating spring phenology have been extensively studied in angiosperm species. However, given that gymnosperms and angiosperms diverged 300 million years ago, phenology may be triggered by different cues in gymnosperm species.
