Stabilizing mechanisms enable dioecious trees to maintain synchrony in spring budburst under climate warming.

New Phytologist
Climate change could reduce dioecious plant fitness if the phenology of males and females responds differently to temperature. However, the extent to which spring phenological responses to climate differ between sexes in wind-pollinated dioecious trees ...

Improving the budburst phenology subroutine in the forest carbon model PnET

Ecological Modelling, 2007
Abstract 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.

Variation in seedling budburst phenology and structural traits among southwestern ponderosa pine provenances

, 2020
We used a common garden study to investigate genetic variation in spring budburst phenology, growth, and structural traits of ponderosa pine (Pinus ponderosa Lawson & C. Lawson var.

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 ...

Artificial light reduced the temperature responsiveness of Ginkgo budburst

Journal of Plant Ecology
Urbanization-induced warming advanced the timing of spring budburst, impacting on urban ecosystems. However, how urban artificial light affects the spring budburst and its spatial variation within species distribution are less studied, especially ...

Rootstock effect on budburst of ‘Premier’ low-chill peach cultivar

Scientia Horticulturae, 2007
Abstract 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.

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

Climatic determinants of budburst seasonality in four temperate‐zone tree species

New Phytologist, 1999
Several 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 ...
