Moderate chilling requirement controls budburst for subtropical species in China

Agricultural and Forest Meteorology, 2019
Abstract 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.

A Unified Model for Budburst of Trees

Journal of Theoretical Biology, 2000
Accurate 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 ...

Light pollution is associated with earlier tree budburst across the United Kingdom [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2016
The ecological impact of night-time lighting is of concern because of its well-demonstrated effects on animal behaviour. However, the potential of light pollution to change plant phenology and its corresponding knock-on effects on associated herbivores are less clear. Here, we test if artificial lighting can advance the timing of budburst in trees.

Budburst in Sultana grapevine as influenced by salinity and rootstock

Australian Journal of Experimental Agriculture and Animal Husbandry, 1979
The time to budburst in Sultana grapevine growing on its own root system, or else grafted to Dogridge, 161 3, Harmony, Ramsey (often incorrectly referred to as Salt Creek) rootstocks, was studied in plants that had been irrigated with 0, 12.5, 25, 50 or 75 mM solutions of chloride salts under glasshouse conditions during the previous growing season ...

Frost Avoidance by Selection for Late Budburst in Picea sitchensis

The Journal of Applied Ecology, 1985
1) The date of the budburst of lateral shoots on young Picea sitchensis (Bong.) Carr. trees can be estimated from mean daily temperatures using the model: T = a + b exp (rC), where T is day degrees > 5 IC accumulated from 1 February and C is number of chill days < 5 IC counted from 1 November (Cannell & Smith 1983).

Climatic Warming, Spring Budburst and Forest Damage on Trees

The Journal of Applied Ecology, 1986
SUMMARY (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.

Variation in the chilling requirement and budburst rate of wild Vitis species

Environmental and Experimental Botany, 2014
Cultivated grapevine (Vitis vinifera) is one of the most important agricultural fruit crops in the world and grapevines are often grown in environments very different than the Mediterranean climate from where they were domesticated. To meet the environmental demands of varied climate, grapevine breeders often utilize wild grapevine species for adaptive

WHY DOES EARLY-SEASON HERBIVORY AFFECT SUBSEQUENT BUDBURST?

Ecology, 1999
Delays 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 ...

Phenological timings of leaf budburst with climate change in Japan

Agricultural and Forest Meteorology, 2008
Phenological 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.

Predicted changes in the synchrony of larval emergence and budburst under climatic warming

Oecologia, 1992
The impact of climatic warming on the synchrony of insect and plant phenologies was modelled in the case of winter moth (Operophtera brumata) and Sitka spruce (Picea sitchensis) in the Scottish uplands. The emergence of winter moth larvae was predicted with a thermal time requirement model and the budburst of Sitka spruce was predicted from a ...
