Estimation of voxel count. Voxel count derived from 3D point cloud represents overall volume of developing panicle. a Average voxel counts from all genotypes for a respective treatment (control and HNT) and time-point (week 1, 2, and 3) is shown. Box plot represents range, median and mean (red triangle) for the same. Means connected with similar letter are not significantly different from each other (Student’s t-test; p < 0.1). b Hierarchical clustering analysis of genotypes based on their voxel count in control conditions. c Voxel count for individual genotypes corresponding to cluster I–IV. Y-axis represent voxel count, x-axis indicate time-point (week 1, 2, and 3). C: control (blue line), HNT: high night temperature (red line). Box plot represents range, median and mean (red triangle) for the same. Means connected with similar letter are not significantly different from each other (Student’s t-test; p < 0.1)
