“…flush before high elevation provenances. A similar trend was also observed in provenance trials with other species, Fagus sylvatica L. in Polish and Finnish provenance trials (Chmura & Rozkowski 2002, Westergaard & Eriksen 1997.

“…Southern nurseries are much warmer than northern ones during the fall period. The nursery carryover effect was present in the stock planted in all common garden location as bud flush phenology depends not only on the present (growing) environment, but also on the environment in which the buds were formed (Westergaard & Eriksen 1997, Heide 1993. Based on the study by Westergaard & Eriksen (1997), low temperatures during bud formation of Acer platanoides L. resulted in a more shallow dormancy level, while Heide (1993) indicated that high autumn temperatures delay spring bud flush in Betula species.…”

“…Consequently, any nursery with an environment greatly different from the site of seed origin may alter seedling growth and development after planting (Campbell & Sorensen 1984, Hawkins 1998. Moreover, when northern provenances grown at southern nurseries are planted back in the north, their flushing phenology may be out of phase with that of the local populations because bud flush phenology depends not only on the present (growing) environment, but also on the environment in which the buds were formed (Westergaard & Eriksen 1997, Heide 1993. Therefore, study of nursery carryover effects is another factor needed to consider before developing any seed transfer guidelines.…”

“…However, recent data indicate that low temperatures control growth cessation and dormancy induction in these species independently of photoperiodic conditions Heide and Prestrud, 2005). In addition, temperature may affect the rate of dormancy acquisition and depth of dormancy in very different woody species (Westergaard and Eriksen, 1997;Junttila et al, 2003;Fennell et al, 2005;Svendsen et al, 2007). For example, high autumn temperatures during SD dormancy induction significantly increase the chilling requirement for dormancy release in alder [Alnus glutinosa (L.) Moench.]…”

Dormancy is an adaptive mechanism that enables woody plants to survive the freezing temperatures of winter. This complex process is characterized by the cessation of meristem activity, which is accompanied by winter bud set, extensive metabolic remodelling, an acquired high tolerance to cold and, in deciduous trees, by leaf senescence and abscission. The induction of dormancy occurs in response to seasonal environmental signals. In most woody plants, shortening of the photoperiod induces growth cessation, bud set, and some degree of cold acclimation. The subsequent drop in temperature then leads to a greater tolerance to cold and leaf fall. Experimental evidence indicates that the phytochrome system plays an important role as a day length sensor, and it has been recently reported that in poplar (Populus tremula x tremuloides), the photoperiodic control of dormancy induction is driven by a molecular mechanism that shares components with the mechanism of the photoperiodic control of flowering time in Arabidopsis. In contrast, the effects of low temperatures are less well understood. Nonetheless, it has been established that the chestnut (Castanea sativa Mill.) circadian molecular clock is disrupted both during winter and in response to cold, with presumable consequences on the general physiology of the plant. However, there is no direct evidence so far for its role in dormancy regulation.Additional key words: bud set, circadian clock, cold acclimation, endodormancy, photoperiodism, phytochrome. ResumenRevisión. Control molecular del establecimiento de la dormancia invernal en los árboles La dormancia es un mecanismo adaptativo que capacita a las plantas leñosas para sobrevivir a las bajas temperaturas invernales. Este complejo proceso se caracteriza por el cese de la actividad de los meristemos, y va acompañado del desarrollo de las yemas de otoño, de notables modificaciones metabólicas, de la adquisición de una elevada tolerancia al frío y, en las especies caducifolias, de la senescencia y abscisión de las hojas. La inducción de la dormancia responde a señales medioambientales. En la mayoría de las plantas leñosas el acortamiento del fotoperiodo induce el cese del crecimiento, la formación de las yemas de otoño y una moderada aclimatación al frío. Después, la bajada de las temperaturas induce una mayor tolerancia al frío y la caída de las hojas. La evidencia experimental indica que el sistema de los fitocromos juega un papel importante como sensor de la duración del día y recientemente se ha comprobado que el control fotoperiódico de la inducción de la dormancia en chopo ocurre mediante un mecanismo molecular que tiene elementos comunes con el que controla la transición floral en respuesta al fotoperiodo en Arabidopsis. La influencia de las bajas temperaturas es menos conocida. El reloj circadiano del castaño (Castanea sativa Mill.) se altera durante el invierno y en respuesta al frío, lo que debe tener importantes consecuencias sobre la fisiología general de la planta. Sin embargo, no hay todavía evidenc...

Boreal tree species are excellent tools for studying tolerance to climate change. Bud phenology is a trait, which is highly sensitive to environmental fluctuations and thus useful for climate change investigations. However, experimental studies of bud phenology under simulated climate change outdoors are deficient. We conducted a multifactorial field experiment with single (T, UVA, UVB) and combined treatments (UVA+T, UVB+T) of elevated temperature (T, +2°C) and ultraviolet‐B radiation (+30% UVB) in order to examine their impact on both male and female genotypes of aspen (Populus tremula L.). This study focuses on the effect of the treatments in years 2 and 3 after planting (2013, 2014) and follows how bud phenology is adapting in year 4 (2015), when the treatments were discontinued. Moreover, the effect of bud removal was recorded. We found that elevated temperature played a key role in delaying bud set and forcing bud break in intact individuals, as well as slightly delaying bud break in bud‐removed individuals. UVB delayed the bud break in bud‐removed males. In addition, both UVA and UVB interacted with temperature in year 3 and even in year 4, when the treatments were off, but only in male individuals. Axillary bud removal forced both bud break and bud set under combined treatments (UVA+T, UVB+T) and delayed both under individual treatments (T, UVB). In conclusion, male aspens were more responsive to the treatments than females and that effect of elevated temperature and UV radiation on bud set and bud break of aspen is not disappearing over 4‐year study period.
