Intrinsic fluorescence of Humulus lupulus (hops) glandular trichomes through development, using the Olympus Multi-photon FV1000 microscope.

Operating in two-photon excitation mode (720nm in wavelength), autofluorescence was captured in two emission channels, 420-460 nm (false-colour teal) and 485-540 nm (false-colour red).
