  Biophotons are an ultra-weak emission of photons in the visible energy range
from living matter. In this work, we study the emission from germinating seeds
using an experimental technique designed to detect light of extremely small
intensity. The emission from lentil seeds and single bean was analyzed during
the whole germination process in terms of both the different spectral
components through low pass filters and the different count distributions in
the various stages of the germination process. Although the shape of the
emission spectrum appears to be very similar in the two samples used in our
experiment, our analysis is able to highlight the differences present in the
two cases. In this way, it was possible to correlate the various types of
emissions to the degree of development of the seed during germination.
