GROWSCREEN 3D. A, Scaffold with acquisition system. The X displacement stage is mounted to the scaffold and carries the Y and X2 displacement stages. B, Camera surrounded by near-infrared light-emitting diode arrays. C, Overview image composed from 395 single images taken under near-infrared illumination. Some leaf discs are smaller or missing because of insufficient leaf area. D, Typical leaf disc floating in solution inside the well. The surface is slightly bent. E, Leaf numbers (counting from base, including cotyledons) and locations along the lamina (B, base; M, middle; T, tip) at which leaf discs were excised. F, Client application with superimposed information about leaf discs (plant identification number, treatment, leaf number, and location along lamina).
