From: Temperature control of shoot growth and floral initiation in apple (Malus × domestica Borkh.)
Time courses of shoot elongation growth (Panels a, c), and the accumulation of leaves (Panels b, d) for the leading shoot of apple trees of the cultivars ‘Summerred’ and ‘Discovery’ as affected by the indicated temperature treatments under natural light conditions at Ås, Norway, in the year 2016. The vertical lines at 6 weeks of treatment correspond to 13 July. Each point represents the mean of 10 trees for the first 6 weeks of treatment, and of 5 trees for the next 6 weeks
