Fig. 9

Scan point height distributions (SHDs) and height levels of reference measurements. Colored lines show the SHDs for the different height levels derived by step wise cutting of the canopy (violet H1, blue H2, dark green H3, bright green H4, yellow H5, orange H6, red H7). Dashed lines with numbers stand for the average reference measurements of different plant parts. (1 height of the whole plant, 2 flag-leaf, 3 second leaf, 4 third leaf, 5 forth leaf, 6 ear-leaf, 7 ear). Data are shown for the maize genotypes ‘Bonfire’ (a) and ‘Poya’ (b). Overview of the different height levels derived by stepwise cutting of the canopy (c) (maize drawings adapted from http://www.openclipart.org); for details see Table 2
