“…We further focused on cherry trees of the cultivar 'Summit' and here we report on data derived for the seasons 2014/15-2016/17. The cultivar 'Summit' was chosen due to the expected larger fruit size, of potentially 35 mm diameter, having attractive potential for practical cultivation resulting in high yields [26].…”

“…After changes of WC in the buds, the following increase of the NC at SG can be seen as an indication for stepwise rising sink activity by the initially translocation of essential elements, as well known for N [53]. On this basis, metabolism starts in general to increase and resulted subsequent in markedly assimilate accumulation, like FW and DW, which reflected the strong growth, differentiation and development of different organs of cherry flowers inside the bud, starting at GT (Table 1).…”

“…Of the two approaches, the former is often employed with the criteria to determine CR by allocating CR as when in-field chill accumulation leads to a 30-50% of bud break after 7 to 10 days in the forcing chamber (Hauagge & Cummins, 1991; Ruiz et al , 2007; Viti et al , 2010; Campoy et al , 2012; Castède et al , 2014). This criteria can vary by study with for instance, CR being determined using the emergence of only 3-4 flowers in the forcing chamber (Chmielewski & Götz, 2016; Götz et al , 2017).…”

13Evaluation of chilling requirements (CR) of cultivars of temperate fruit trees provides key 14 information to assess regional suitability, according to winter chill, for both industry expansion 15 and ongoing profitability as climate change continues. Traditional methods for calculating CR 16 use climate controlled chambers and define CR using a fixed budburst percentage, usually close 17 to 50% (CR-50%), without considering the productivity level associated to this percentage. This 18 CR-50% definition may underestimate the real CR of tree crops for optimal productivity. This 19 underestimation is particularly important to consider as winter chill accumulation is declining 20 in many regions due to climate change. In this work we used sweet cherry to analyse the 21 traditional method for calculating CR in many Rosaceae species (CR-50%) and compared the 22 results with more a restrictive, productivity focused method, with CR defined with a 90% bud 23 2 break level (90%, CRm-90%) close to the optimal budburst which assures productivity. Climate 24 projections of winter chill suitability across Europe using CR-50% and CRm-90% were 25 calculated. Regional suitability landscape was highly dependent on the method used to define 26 CR and differences were found for a wide area of the European geography, both cold and mild 27 winter areas. Our results suggest a need to use an optimal budburst level for the assessment of 28 CR for sweet cherry. The use of traditional methods to determine CR can result in an 29 underestimation of productivity CR with negative consequences for the fruit industry, 30 particularly as climate change advances. 31
