Structural and dynamical analysis of a root system.
Top row: images of a maize plant imaged between the first and ninth days after planting. Bottom row: images of a rice plant imaged between the seventh and eleventh days after planting. Left: decomposition into a seed area and branches distinguished by color. Center: the color-coded time function. Right: the color-coded branch hierarchy.
Fig 3.
A series of three 3D models mimicking a growing root system designed to facilitate the validation of our software.
The branches are labeled as in Table 1. The color-coded model at the far right illustrates the time function.
Table 1.
Comparison of traits measured by hand and computed with DynamicRoots.
Length, vertical depth, and radius are given in millimeters (mm), volume in cubic millimeters (mm3), angle in degrees, and tortuosity is dimensionless. The last column gives the average error of the DynamicRoots results compared to hand measurements.
Fig 4.
Volume dynamics of the root systems in Fig 2; maize at the top and rice at the bottom.
The colored segments within each vertical bar show the volume contributed by individual branches.
Fig 5.
The branching dynamics of rice plants during five consecutive days.
The shading distinguishes day- from night-time, highlighting that more branches are formed during day-time.
