Plant Spectroscopy

It is known that shinning a UV light onto green plants will make the plants fluoresce in the red and blue-green range (You can use this ratio to tell how healthy a plant is). The sun also emits UV light and thus the trees must be fluorescing all day. My guess is that we can't observer the fluoresce with our eye because the light it too weak. But could we pick it up on a spectrometer?
