Pavement induced soil warming accelerates leaf budburst of ash trees [PDF]
Urban Forestry and Urban Greening, 2016 Abstract Urban greening is becoming increasingly popular in cities around the world, which is leading to the planting of more and more trees in paved areas in urban environments. However scientifically it is not well understood how pavement may impact tree greening efforts.

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

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 ...

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 ...

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.

Climatic determinants of budburst seasonality in four temperate‐zone tree species
New Phytologist, 1999Several physiological processes controlling tree phenology remain poorly understood and in particular bud dormancy. Many studies have emphasised the action of chilling temperatures in breaking dormancy. However, the effect of the preceding summer temperatures has rarely been investigated although there is some evidence that they may be involved in the ...

Phenological timings of leaf budburst with climate change in Japan
Agricultural and Forest Meteorology, 2008Phenological timing of leaf budburst in plants is important for growth, since early budburst timing extends the growth period of the plant. We estimated the effect of climate change on the phenological budburst timing of four trees throughout four sites in Japan, a region with few studies on this topic.

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.
