“…The effect of non-optimal chilling temperatures postponing the start of bud development has previously been shown by Bailey and Harrington (2006). Harrington et al (2010) also suggested that temperatures that are some degrees above freezing are the most effective in satisfying the chilling requirement for dormancy release, while higher autumn temperatures, as occurred in the greenhouse, would not be as effective.…”

“…3). The reason for using the Krutzsch index instead of scales specifically developed for Douglas fir (Thomson and Moncrieff 1982;Bailey and Harrington 2006;Harrington et al 2010) was that we had a special interest in comparing the early bud burst patterns of Norway spruce and Douglas fir, which are included in the Krutzsch index (stages 1 and 2) but not in the specific Douglas fir scales.…”

Key message The Douglas fir provenance Three Valley was found most suitable for planting in mid-Sweden. Greenhouse tests can most likely predict how different Douglas fir provenances will perform in the field. Abstract The need for species that will grow well through ongoing climate change has increased the interest in Douglas fir [Pseudotsuga menziesii (Mirb.) Franco] in Sweden. One of the most common problems seen in plantations of Douglas fir seedlings is damage caused by late spring frost, known to be highly correlated with the timing of bud burst. The objective of this study was to investigate spring-related bud development under Nordic conditions of seven Douglas fir provenances and to compare data with a local provenance of Norway spruce (Picea abies (L.) Karst). Results from a field trial and a greenhouse-based study were compared. The interior Douglas fir provenances exhibited an earlier bud burst than coastal provenances, both in the greenhouse and in the field trial. When comparing differences within the groups of interior and coastal Douglas fir provenances, no differences could be found. The local Norway spruce, only grown in the greenhouse, showed an intermediate bud development profile similar to the interior Douglas fir provenance Three Valley. We therefore suggest that Three Valley could be planted at the same locations as the investigated local provenance of Norway spruce in mid-Sweden. To avoid spring frost damage the Douglas fir seedlings need to be frozen stored and planted late in spring. Planting under shelterwood can also help protect the seedlings from spring frost damages. As similar results for bud development patterns of Douglas fir and Norway spruce provenances were obtained from the greenhouse and field trials, greenhouse tests could facilitate selection of provenances.

“…Wheeler et al (2000) argue, for example, that variance in temperature during critical stages of crop development could affect crop and seed yields. Harrington et al (2010) demonstrate that fluctuations between warm and cool temperatures are essential for predicting the date of budburst in Douglas-fir (Psuedotsuga mensiesii ) forests. Even midge (Chironomidae) emergence patterns are often strongly tied to diel water temperature variations (Ward and Stanford 1982).…”

Abstract. Alterations in variance of riverine thermal regimes have been observed and are predicted with climate change and human development. We tested whether changes in daily or seasonal thermal variability, aside from changes in mean temperature, could have biological consequences by exposing Chinook salmon (Oncorhynchus tshawytscha) eggs to eight experimental thermal regimes. Thermal variance impacted both emergence timing and development at emergence. Further, genetics influenced the magnitude of that response. Ecological implications include: (1) changes in thermal variability, independent of warming, have the potential to alter the timing of life history processes, (2) the commonly-used degree day accumulation model is not sufficient to predict how organisms respond to altered temperature regimes, and (3) there are likely to be genetic differences in how individuals and populations respond to future water temperature regimes.

“…However, the range of chilling temperatures required for an efficient release from endodormancy has not yet been clearly identified (Dantec et al 2014). Recent advances suggest that this range of chilling temperature is likely to be species-specific (Laube et al 2014) and may cover a broader spectrum than commonly assumed (Harrington et al 2010). Once endodormancy is released, warm temperatures have a clear positive effect on bud development during ecodormancy, with a warmer spring leading to an earlier budburst (Sarvas 1972;Sarvas 1974;Campbell and Sugano 1975;Lang et al 1987;Caffarra et al 2011b).…”

Abstract& Key message We demonstrate that, beyond leaf phenology, the phenological cycles of wood and fine roots present clear responses to environmental drivers in temperate and boreal trees. These drivers should be included in terrestrial ecosystem models. & Context In temperate and boreal trees, a dormancy period prevents organ development during adverse climatic conditions. Whereas the phenology of leaves and flowers has received considerable attention, to date, little is known regarding the phenology of other tree organs such as wood, fine roots, fruits, and reserve compounds. & Aims Here, we review both the role of environmental drivers in determining the phenology of tree organs and the models used to predict the phenology of tree organs in temperate and boreal forest trees. & Results Temperature is a key driver of the resumption of tree activity in spring, although its specific effects vary among organs. There is no such clear dominant environmental cue involved in the cessation of tree activity in autumn and in the onset of dormancy, but temperature, photoperiod, and water stress appear as prominent factors. The phenology of a given organ is, to a certain extent, influenced by processes in distant organs. & Conclusion Inferring past trends and predicting future trends of tree phenology in a changing climate requires specific phenological models developed for each organ to consider the phenological cycle as an ensemble in which the environmental cues that trigger each phase are also indirectly involved in the subsequent phases. Incorporating such models into terrestrial ecosystem models (TEMs) would likely improve the accuracy of their predictions. The extent to which the coordination of the phenologies of tree organs will be affected in a changing climate deserves further research.
