Fig. 6: Leaf width and length responded similarly to environmental conditions in fields and indoor platforms.

a Relationship between leaf width and the cumulated light intercepted by plants during leaf widening. b Relationship between leaf length and leaf-to-air vapor pressure deficit (VPDla: mean of maximum daily values) during leaf elongation. Each point, one experiment and leaf rank. Leaf width and length values of four leaf ranks (8–11, circles, squares, diamonds and triangles, respectively) were corrected for leaf rank so equivalent values for leaf 8 are presented44. Blue dots: field, red dots: indoor platform. Black lines, linear regressions. In a, r = 0.83 (95% CI = 0.73-0.89), n = 64, df = 62, p-value < 2.2E-16. In b, r = −0.62 (95% CI = −0.78-0.40), n = 44, df = 42, p-value = 6.2E-06. Significance of the correlation coefficients was tested using two-sided t-test.
