Summary: | Unsuitable postharvest management is one of the most serious problems
that floriculture has to face. An option for reducing postharvest
losses is to use automatic systems for flower sorting and
classification, which yield consistent results, reduce costs and speed
up these tasks. The objective of this work was show the potential of
spectral reflectance to distinguish different postharvest development
stages of calla lily flowers, Zantedeschia aethiopica (L.) Spreng.,
aiming the use of this technology within automatic systems for flower
classification. The measuring equipment was a spectrometer connected to
a portable computer and configured for reflectance data acquisition in
the 400 to 1000 nm range. Based on the results, it was verified a
differentiation between the spectral reflectance curves of calla lily
flowers, with gradual decreases on the measured values according to the
increase of the senescence stages. Thus, the spectral reflectance has
potential to be used in the development of automatic systems for
postharvest classification of calla lily flowers. |
