The increase in global mean air temperature is likely to affect the soil temperatures in agricultural areas. This study aims to study the effects of winter soil warming on the responses of wheat to low temperature stress in spring. Wheat plants were grown under either normal or increased soil temperature by 2.5°C for 82 days in winter. The physiological and yield responses of the plants to a 2-day low temperature stress (4/2°C in the day/night) at jointing stage were investigated. After exposing to low spring temperature, the plants that had experienced winter soil warming showed lower leaf and root water potential, lower oxygen scavenging capacity and poor photosynthetic performance as compared with the plants grown under normal soil temperature during winter. WL plants had significantly lower sugar content in shoot than the CL plants, which might have contributed to their higher susceptibility to low temperature. In addition, winter soil warming exacerbated the negative effects of low spring temperature on grain yield.

“…Earlier studies show that spring events, such as leaf unfolding or needle flush, are particularly sensitive to temperature (Lechowicz, 1995;Sarvas, 1972Sarvas, , 1974. In accordance with our results on the after effect of the treatments in 2015, Fu et al (2012) found that Betula (Pagter, Andersen, & Andersen, 2015), and bud break is associated with low levels of soluble sugars (Lipavská, Svobodová, & Albrechtová, 2001). In this case, the enhanced temperature would have reduced the sugar concentrations, as was also seen in B. pendula seedlings (Riikonen et al, 2013), which could be the mechanism behind the temperature-forced bud break in 2014 and 2015.…”

“…It can be speculated that in addition to the carry‐over effect of the temperature treatment, the enhanced bud break in intact individuals in 2015 could have also resulted from the previous year high autumn temperature which might have influenced the subsequent bud burst. Elevated temperature can alter the sugar levels in buds (Pagter, Andersen, & Andersen, ), and bud break is associated with low levels of soluble sugars (Lipavská, Svobodová, & Albrechtová, ). In this case, the enhanced temperature would have reduced the sugar concentrations, as was also seen in B. pendula seedlings (Riikonen et al., ), which could be the mechanism behind the temperature‐forced bud break in 2014 and 2015.…”

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.

“…The CD accumulation then departs from that plateau in the autumn just before GDD accumulation ceases. Between these dates, T avg ≥ T base and vegetation defenses against freezing are limited while net primary productivity is generally dedicated to growth and reproduction [Schenker et al, 2014;Vitasse et al, 2014;Körner, 2015;Pagter et al, 2015]. Our resulting plateau-based growing season is several days longer than the frost-free season for the same year.…”

We assess long‐term climatological means, trends, and interannual variability around the western end of Lake Superior during 1984–2013 by using available weather station data. Our results focus on changes in basic and derived climate indicators from seasonal and annual temperature and precipitation, to the traditionally defined frost‐free season, to a novel definition of the climatological growing season. We describe seasonal and year‐to‐year climate variability that influences forest phenology, using an alternative growing season metric that is based on the warm‐season plateau in accumulated chilling days as an indicator of environmental triggers for vegetation growth and senescence. Our results indicate +0.56°C regional warming during our 30 year study period, with cooler springs (−1.26°C) and significant autumn warming (+1.54°C). The duration of the climatological growing season has increased +0.27 d/yr, extending primarily into autumn. Summer precipitation in our study area has declined by an average −0.34 cm/yr, potentially leading to moisture stress that impairs vegetation carbon uptake rates and can render the forest more vulnerable to disturbance. Many changes in temperature, precipitation, and climatological growing season are most prominent in locations where Lake Superior exerts a strong hydroclimatological influence, especially the Minnesota shoreline and in forest areas downwind (southeast) of the lake. Observed trends in lake temperature and ice phenology have also changed, coincident with a large‐scale climatological regime shift around 1998. A number of factors are likely altering forest phenology and the role of the forest in the climate system of this ecologically important and highly varied forest‐and‐lake region.
