Representative growth profiling and harvesting. A) Representative surface plot of relative elongation growth rates (% change per hour,
vertical axis) plotted against the number of segments (defined by optical marker tags)
from the apex downwards, over the duration of the imaging period in 10â€‰minutes intervals.
The darker grey-shaded, nearest profile denotes the last 10-minute interval before
harvest, depicted in the greater detail in the right-hand scatterplot. B) Corresponding scatter plot of growth rates (% change in length per hour) against
distance from the stem base for specific segments. Segments are numbered from the
top of the plant downwards in the right-hand margin. The LOWESS regression curve follows
the best fit through the growth rate data for this plant over a given 10' interval.
Green dotted lines represented 65% confidence intervals for the LOWESS regression
curve. Closed-box/arrow indicates the stem position that matches the maximum growth
rate of the regression curve (segment 5), plotted as the right-most vertical dotted
line, while the open-box/arrow indicates the first position below the top of the stem
where the growth rate falls to zero (segment 10). C) Harvesting zones for young (YNG), maximum growth-rate (MGR), cessation (CSS), and
stem base (OLD) zones based upon LOWESS curve. See methods for description of zone
establishment. See Additional file 1: Figure S1 for complete set of 34 growth kinematic profiles.
