Figure S1. Samples of the range of chillingresponses (% achievement of bud-stage 4) found in differentcultivars in the year 1 experiment. All records taken after45 days’ warming at permissive temperature.
Figure S2. Samples of the range of chillingresponses (% achievement of bud-stage 4) found in differentcultivars in the year 1 experiment. All records taken after45 days’ warming at permissive temperature.
Table S1. Blackcurrant germplasm used in experiments in each year.
Table S2. Parameters in equations 1–2estimated for achievement of bud-stage 2 after 45 days’ warming, estimated across data for all the cultivars in year 1 (first part of table) and for some representative cultivars (second part of table). Data for all lengths of chilling period are fitted together. The sums of squares (SS) are for 400 data points for the full models and 20 data points for the single cultivars.
Table S3. Effectiveness of varying temperature regimes (year 2), expressed as the percentage achievement of each of the four bud stages. Results are the averages of all cultivars used in year 2.
