Fig 3. Slopes of the relationship between the length of growing season of five genotypes (Beaupre, Fritzy Pauley, Raspalje, Trichobel and Unal) in 2015 and mean January, July and annual temperatures experienced by the parent trees.

Mean weighted (bootstrapped) slopes are indicated by black points and error bars denote 95% confidence intervals (upper and lower) across 500 bootstrapped values. Error bars denote 95% confidence intervals. ‘Shorter’ means that growing season is shorter with increasing temperature and ‘Longer’ means that growing season is longer with increasing temperature.
