Why Does Early-Season Herbivory Affect Subsequent Budburst?
Ecology, 1999Delays in budburst in the year following herbivory have previously been attributed to a defensive response to early-season herbivory or localized resource deficien- cies (resource availability hypothesis) limiting bud development. We carried out field ex- periments to test the resource availability hypothesis as well as the crown architecture ...

Budburst phenology of white birch in industrially polluted areas
Environmental Pollution, 2007Effects of environmental contamination on plant seasonal development have only rarely been properly documented. Monitoring of leaf growth in mountain birch, Betula pubescens subsp. czerepanovii, around a nickel-copper smelter at Monchegorsk hinted advanced budburst phenology in most polluted sites. However, under laboratory conditions budburst of birch

Automated sensor for flowering and vegetative budburst
2013 IEEE Sensors Applications Symposium Proceedings, 2013We describe a sensor for measuring budburst and blossom in plants and trees. A pair of plastic optical fibers is placed behind a bud. One fiber carries modulated light to the bud and the other fiber carries reflected light to detector electronics. When the plant's bud opens, the amount of reflected light changes.

Predicting the Timing of Budburst in Temperate Trees
The Journal of Applied Ecology, 19921. Four models for predicting budburst in northern hardwood trees, based on response to spring warming alone, or with the response to spring warming modified by winter chilling and photoperiod, were compared. An historical, 18-year budburst record, and artificial datasets with budburst dates generated according to each of four conceptual models, were ...

Rootstock effects on budburst and flowering in kiwifruit
Scientia Horticulturae, 1994Abstract Effects of five Actinidia rootstocks on budburst and flowering characteristics of ‘Hayward’ kiwifruit scions were examined. Compared with a standard clonal Actinidia deliciosa rootstock, clones of Actinidia hemsleyana, Actinidia eriantha and Actinidia rufa increased ‘Hayward’ flower numbers per cane by 110%, 73% and 30%, respectively.

A Unified Model for Budburst of Trees
Journal of Theoretical Biology, 2000Accurate plant phenology (seasonal plant activity driven by environmental factors) models are vital tools for ecosystem simulation models and for predicting the response of ecosystems to climate change. Since the early 1970s, efforts have concentrated on predicting phenology of the temperate and boreal forests because they represent one-third of the ...

Climatic Warming, Spring Budburst and Forest Damage on Trees
The Journal of Applied Ecology, 1986SUMMARY (1) If future C02-induced warming of 2 'C increased the incidence of warm springs, of the type that have occurred in Britain during this century, then warming would induce earlier blossoming and budburst in many temperate trees, with an increase in the risk of subsequent damaging frosts.

Bayesian calibration of the Unified budburst model in six temperate tree species
International Journal of Biometeorology, 2011Numerous phenology models developed to predict the budburst date of trees have been merged into one Unified model (Chuine, 2000, J. Theor. Biol. 207, 337-347). In this study, we tested a simplified version of the Unified model (Unichill model) on six woody species.

Tree roots lack dormancy and can advance budburst when warmed
2023The initiation of tree growth in spring is typically linked to leaf-out. Bud dormancy drives budburst timing while dormancy of tree roots has largely remained unexplored, although the latter can shape below-ground growth and carbon dynamics. As roots experience different temperatures from buds, their dormancy dynamics and growth timing can differ and ...

Moderate chilling requirement controls budburst for subtropical species in China
Agricultural and Forest Meteorology, 2019Abstract It is well known that spring phenology has advanced in temperate regions over the last few decades in response to climate change. However, we understand much less about climate-driven changes in phenology within subtropical and tropical regions, where the timing of events is less predictable and has not been well-studied.
