Moreover, the change of color of the rind of some fruits occurs due to the accumulation of carotenides and antocianinas in the epidermis (Olmo et al., 2000; Agati et al., 2005). The technique of the fluorescence of clorofila was used by Lai et al. (2007) to analyze main metabolic the secondary ones produced in the epidermis of tomatoe fruits during the matureness, that had verified marcante change in the standard of pigment composition, with gradual degradation of clorofila and increase of the concentration of carotenides until the phase of complete maturation. Conclusion The species Prunus Lusitanica presented greater text of clorofila in all the measurements. Bibliography Baker, N.R. (2008) Chlorophyll fluorescence: Probe of photosynthesis in alive.
