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 ...

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,

Frost Avoidance by Selection for Late Budburst in Picea sitchensis
The Journal of Applied Ecology, 19851) 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).

Rootstock effect on budburst of ‘Premier’ low-chill peach cultivar
Scientia Horticulturae, 2007Abstract To determine the effect of rootstock with different chilling requirements on the bud break of the low-chill ‘Premier’ peach cultivar (150 CH), the trees grafted on ‘Newbelle’ (150 CH) and ‘O’Henry’ (750 CH) seedling rootstocks were forced in a glasshouse after being subjected to 100, 200 and 300 CU chilling.

Budburst in Sultana grapevine as influenced by salinity and rootstock
Australian Journal of Experimental Agriculture and Animal Husbandry, 1979The 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 ...

Relationship between sugar maple budburst phenology and pear thrips damage
Canadian Journal of Forest Research, 1991The relationship between budburst phenology and damage by the pear thrips (Taeniothripsinconsequens (Uzel) (Thysanoptera: Thripidae)) to sugar maple (Acersaccharum Marsh.) foliage was investigated in two studies. In the first study, seedlings in cages were exposed to adult thrips at different stages of budburst.

Performance of several models for predicting budburst date of grapevine (Vitis vinifera L.)
International Journal of Biometeorology, 2009The budburst stage is a key phenological stage for grapevine (Vitis vinifera L.), with large site and cultivar variability. The objective of the present work was to provide a reliable agro-meteorological model for simulating grapevine budburst occurrence all over France.

Improving the budburst phenology subroutine in the forest carbon model PnET
Ecological Modelling, 2007Abstract The timing of leaf expansion in spring and leaf senescence in fall determines growing season length; hence leaf phenology is important in modelling carbon production. Previous work monitoring net ecosystem exchange using eddy flux technology found phenological timing to be a key factor determining ecosystem carbon balance.

Predicted changes in the synchrony of larval emergence and budburst under climatic warming
Oecologia, 1992The 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 ...
