Andrea B. Posted January 14, 2018 Share Posted January 14, 2018 Dave, remind me how you are making the fluorescence photos. Are you bringing the specimens indoors to a studio setting? Or are you shooting in the field (or garden) using a dark cloth? That blue fluor is so intense! Link to comment
DaveO Posted January 16, 2018 Author Share Posted January 16, 2018 Andrea, I admitted defeat long ago trying to do UVIVFL shots in the big outdoors so yes, they are all indoor dark room shots. Most of my UVIVFL images these days are cuttings taken from a garden grown plant unless I manage to kidnap it on the way to be planted in the garden I suspect the intense blue is lignin but I've never got around to finding a pure specimen of lignin.

Andrea B. Posted January 20, 2018 Share Posted January 20, 2018 I have lignin associated with tree bark in my head! So there could be lignin in these Verticordia flower petals/sepals? Link to comment
