Photocontrol of bud burst involves gibberellin biosynthesis in Rosa sp.

Journal of Plant Physiology, 2012
Light is a critical determinant of plant shape by controlling branching patterns and bud burst in many species. To gain insight into how light induces bud burst, we investigated whether its inductive effect in rose was related to gibberellin (GA) biosynthesis.

Simulation of forest tree species’ bud burst dates for different climate scenarios: chilling requirements and photo-period may limit bud burst advancement

International Journal of Biometeorology, 2016
This study investigates whether the assumed increase of winter and spring temperatures is depicted by phenological models in correspondingly earlier bud burst (BB) dates. Some studies assume that rising temperatures lead to an earlier BB, but even later BB has been detected.

Dormancy and bud burst in Sultana vines

2017
Dormancy and bud burst have been studied for sultana vines in the Murray Valley, Australia. The vines are in deep dormancy at the beginning of autumn and the intensity of dormancy decreases gradually during autumn and winter. Bud burst of cuttings taken during the dormant period occurs the more rapidly the higher the temperature at which they are held.

Dehydrins expression related to timing of bud burst in Norway spruce

Planta, 2008
Cold deacclimation and preparation to flushing likely requires rehydration of meristems. Therefore, water stress related genes, such as dehydrins (DHN), might play an important role in providing protection during winter dormancy, deacclimation and bud burst timing processes.

Varying temperature sensitivity of bud-burst date at different temperature conditions

International Journal of Biometeorology, 2019
The relationship between the rate of development (DR) of bud-burst and temperature may be nonlinear, which could lead to varying temperature sensitivity (TS) of budburst date under different climate conditions. In order to determine the functional form between DR/TS and temperature, we gathered twigs with flower buds of five woody plants (Malus ...

Acetylated H4 histone and genomic DNA methylation patterns during bud set and bud burst in Castanea sativa

Journal of Plant Physiology, 2009
The relationships between genomic DNA cytosine methylation, histone H4 acetylation and bud dormancy in Castanea sativa are described. Acetylated H4 histone and genomic DNA methylation patterns showed opposite abundance patterns during bud set and bud burst.

Prediction of bud burst in Douglas-fir by degree-day accumulation

Canadian Journal of Forest Research, 1982
A temperature threshold, starting date, and heat unit total are required for use of degree-days. The three parameters are not independent, the heat unit total depending largely on the threshold used. An iterative solution is presented to estimate these parameters for Douglas-fir (Pseudotsugamenziesii (Mirb.) Franco) bud burst from observations of ...

Photoperiod sensitivity of bud burst in 14 temperate forest tree species

Agricultural and Forest Meteorology, 2012
Abstract The timing of spring phenology of trees reflects a trade-off between a longer growing season and a lower risk for damage by late freezing events. Temperature is driving rates of development directly, but given the high inter-annual variability in weather, it is a poor environmental cue for the progression of the season and thus, the period ...

Studies on the sultana vine. II. The course of bud burst.

Australian Journal of Agricultural Research, 1955
Sultana vines were examined during bud burst for four seasons, and the date on which each shoot arose was noted. The shoots were later classified as fruitful, barren, or defective. The vines were pruned uniformly in the first season, and two pruning treatments were compared in the other three seasons. In all cases the mean time of bursting a t each bud
