“…To determine the phenotypes of the four apricot genotypes, the bloom dates from 1999 to 2013 were recorded. Genotypes A1956 and A2137 reached 50% bloom after an average of 60 Julian calendar days and are hereafter referred to as "early blooming" (Audergon, 1993;Dirlewanger et al, 2012;Andreini et al, 2014;Quero-Garcia et al, 2016). Genotypes A660 and A1267 reached 50% bloom after more than 70 Julian days on average ("late blooming") ( Supplementary Figure 2A).…”

“…Although the vast majority of case studies have reported significant advances in flowering times over the years (Chmielewski et al, 2011;Chmielewski and Rotzer, 2001;Fitter and Fitter, 2002;Fu et al, 2015;Legave and Clauzel, 2006;Menzel et al, 2006;Parmesan, 2007;Parmesan and Yohe, 2003;Root et al, 2003;Wolfe et al, 2005), the literature includes a considerable number of records describing observations of flowering times that have remained unchanged or even experienced delays Elloumi et al, 2013;Fitter and Fitter, 2002;Kozlov and Berlina, 2002;Legave et al, 2013;Menzel et al, 2006;Yu et al, 2010). Recent studies have indicated that the response of plant phenology to temperature is more complex than simply an advance due to warming (Andreini et al, 2014;Chuine et al, 2016;Cook et al, 2012;Guo et al, 2015;Pope et al, 2014).…”

Temperatures are rising across the globe, and the UK is no exception. Spring phenology of perennial fruit crops is to a large extent determined by temperature during effective chilling (endo-dormancy) and heat accumulation (eco-dormancy) periods. We used the apricot flowering records of the UK National Fruit Collections (NFC) to determine the influence of temperature trends over recent decades (1960 to 2014) on apricot (Prunus armeniaca L.) flowering time. Using Partial Least Squares (PLS) regression, we determined the respective periods for calculating chill and heat accumulation. Results suggested intervals between September 27 th and February 26 th and between December 31 st and April 12 th as the effective chilling and warming periods, respectively. Flowering time was correlated with temperature during both periods, with warming during chilling corresponding to flowering delays by 4.82 d°C-1 , while warming during heat accumulation was associated with bloom advances by 9.85 d°C-1. Heat accumulation started after accumulating 62.7 ± 5.6 Chill Portions, and flowering occurred after a further 3744 ± 1538 Growing Degree Hours (above a base temperature of 4°C, with optimal growth at 26°C). When examining the time series, the increase in temperature during the chilling period did not appear to decrease overall chill accumulation during the chilling period but to delay the onset of chill accumulation and the completion of the average chill accumulation necessary to start heat accumulation. The resulting delay in heat responsiveness appeared to weaken the phenology-advancing effect of spring warming. These processes may explain why apricot flowering time remained relatively unchanged despite significant temperature increases. A consequence of this may be a reduction of frost risk for early flowering crops such as apricot in the UK.

“…Although recent studies have shown the value of a wide range of data 26,27 , most analyses for fruit tree crops are based on phenological data for a very limited number of experimental sites, and rarely include more than two cultivars within a species (e.g., refs 28,29). …”

“…Past research have shown the value of using heterogeneous records combined from different sites and cultivars for the evaluation of climate change response and phenology modelling approaches (e.g., refs 21,35–38). In particular, phenology models have been successfully tested and optimized using data sourced from different sites 27,38 . Therefore, we want to highlight the value of this dataset, combining data from various geographical sites and contrasted cultivars, for potential multi-environment analyses yet to be implemented.…”

Professional and scientific networks built around the production of sweet cherry (Prunus avium L.) led to the collection of phenology data for a wide range of cultivars grown in experimental sites characterized by highly contrasted climatic conditions. We present a dataset of flowering and maturity dates, recorded each year for one tree when available, or the average of several trees for each cultivar, over a period of 37 years (1978–2015). Such a dataset is extremely valuable for characterizing the phenological response to climate change, and the plasticity of the different cultivars’ behaviour under different environmental conditions. In addition, this dataset will support the development of predictive models for sweet cherry phenology exploitable at the continental scale, and will help anticipate breeding strategies in order to maintain and improve sweet cherry production in Europe.
