Fig. S1. Histogram plots for radiographic images of jojoba seeds, lot 1. The red line indicates the threshold determined by the Auto Threshold command in ImageJ software. Each image was composed of 25 seeds.

Fig. S2. Histogram plots for radiographic images of jojoba seeds, lot 2. The red line indicates the threshold determined by the Auto Threshold command in ImageJ software. Each image was composed of 25 seeds.

Fig. S3. Histogram plots for radiographic images of jojoba seeds, lot 3. The red line indicates the threshold determined by the Auto Threshold command in ImageJ software. Each image was composed of 25 seeds.

Fig. S4. Histogram plots for radiographic images of jojoba seeds, lot 4. The red line indicates the threshold determined by the Auto Threshold command in ImageJ software. Each image was composed of 25 seeds.

Fig. S5. Histogram plots for radiographic images of jojoba seeds, lot 5. The red line indicates the threshold determined by the Auto Threshold command in ImageJ software. Each image was composed of 25 seeds.
