Helianthus annuus morphological diversity and the associated high-resolution images available in HeliantHOME. (A) Assorted selection of H. annuus inflorescences images taken from top (left panel) and bottom (right panel) showing morphologic diversity; (B) Example of the measurements performed for each single inflorescence using Fiji; (C) Measurements recorded using Fiji for leaf traits; (D) Example of a high-resolution scan of a leaf section used to detect trichome density (E) Assorted selection of leaf images as an example of the morphological diversity observed in the wild; (F) Assorted selection of primary branches sections as an example of the amount of variation observed; (G) Close up for two different branches and description of the measured traits; (H) Scanned image obtained for each single individual of eight randomly selected seeds. (I) Assorted selection of seeds showing variability observed in the wild for this trait. (J) Screenshot from HeliantHOME images section, example showing for each individual (in this case IDs: ANN0801 and ANN0802 (i) the first three inflorescences both from top/bottom (camera captured); (ii) a single young, fully expanded leaf at anthesis both adaxial and abaxial sides (scanned); (iii) lateral image of the whole young plant before flowering (camera captured); (iv) image captured from above of the whole young plant (camera captured); (v) section of primary branch (scanned); (vi) random selection of 8 seeds coming from a cross within members of the same population (scanned at 2400 dpi high resolution) and (vii) 2400 dpi high resolution scan of a section of the abaxial side of the same leaf recorded in ii).
