The study reveals the effect of natural dyes Curcuma longa (rhizome) and Nyctanthes arbor-tristis (corolla tube) on various plant tissues under fluorescence microscopy. The results indicated that the auto-fluorescence was seen in some of the tissues of unstained monocot and dicot stem sections. The use of Curcuma longa dye along with different chemical mordants leads to various colors and intensity of fluorescence under different excitation filters (violet 400-450; blue 450-500; green 500-570; yellow 570-610 and red 610-7
