Fig. 2

Correlation of traits derived from 3D reconstruction, 2D scanning and manual measurements of inflorescence-related traits. Using PI-Plat, developing panicles were imaged on weekly basis (week 1, 2, and 3). For a respective panicle, multi-view images were used for 3D reconstruction to extract voxel count. Also, 2D pixel count was estimated for developing panicle. Phenotypic traits from mature panicle were analyzed by flatbed scanner (projected surface area and seed count), and manual measurements (seed number and weight). Pearson correlation analysis for traits of primary interest is represented. Similar analysis for other extracted traits is listed in Additional file 5. Histograms and red line represent the distribution of each trait. p value for significant correlation is shown in red (***p < 0.001, **p < 0.01, *p < 0.1), n = 55
