Figure 2From: Synchronous high-resolution phenotyping of leaf and root growth in Nicotiana tabacum over 24-h periods with GROWMAP-plantLeaf RGR patterns (a, c, e) and root velocity patterns (b, d, e) acquired simultaneously for N. tabacum seedlings under three different conditions for the root system. (a, b) Roots are growing in the dark at 22°C substrate temperature (control, n = 3). (c, d) Roots growing in the dark at 10°C substrate temperature (root cooling, n = 4). (e, f) Roots subjected to diel light–dark cycles at 22°C substrate temperature (root illumination, n = 4). Error bars are S.E.Back to article page
