Time-series root images of four wheat cultivars under three salinity treatments across the whole growth period

This dataset contains raw root images collected throughout the whole growth period of four wheat cultivars grown under three salinity treatments, with four biological replicates for each treatment–cultivar combination. Root images were acquired at approximately 5-day intervals from the early growth stage to the end of the growth period. The dataset is intended to support the analysis of temporal root growth dynamics and varietal responses to salinity stress. There are three main files: the original root system images, the segmentation model, and the segmented root system images. The file "Root pictures _wheat_rootbox_original.zip" contains the original root system image data; it does not include the full dataset due to its large size. Specifically, it omits the original images from the initial few observation time points, as these showed minimal change and are of less significance. The file "seg-model.pkl" is the segmentation model. The file "Root pictures _wheat_rootbox_seg.zip" contains the root system image data that has been segmented and extracted using the Root Painter software.
