Imaging Capabilities @ APPL

• Visible RGB Camera (Morphology)
• 2 Types of Fluorescence Camera (chlorophyll fluorescence)
• Infrared Camera (Water Relations and Temperature)
• Hyperspectral Camera (Stress, Physiology, & Indices)
• Multispectral Camera (Water Content)
• 3D Laser Scanner (Architecture)
• Plants can be imaged at specific stages with a variety of stress inductions.
• Plants grown in other greenhouses or growth chambers can be brought to APPL to image during the time point of interest.
• Work with the Plant System Biology Group to enhance your research with equipment like the LiCOR 6800, the LiCOR-600, a PTR for Volatile Organic Compounds, etc.!
