 GrowTechnology
and Astec Global have
signed an exclusive agreement to promote and sell the
Seedanalyser (SA10) worldwide through Astec Global. The
Seedanalyser is developed by GrowTechnology B.V. Astec Global is
pleased that it can add the Seedanalyser to the list of its
commercial products.
The Seedanalyser can work complementary to the by Astec Global
developed Q2 machine. Both machines give different information
about the seed-lot quality.
It also fits in the Astec-Global philosophy to bring new
developments to the seed industry worldwide.
The Seedanalyser is developed for a quick evaluation of the seed
maturity in the field. It will give directly information about
the most optimal moment to harvest the seeds. Astec Global is
now testing the suitability of the Seedanalyser during the
cleaning process of the seeds.

Astec-Global) believe that the Seedanalyser can
be used in the future also in other parts of the
seed logistics. |

The measurement is based on
chlorophyll fluorescence. The technique is a very sensitive,
fast, non-destructive method for measuring chlorophyll in seeds.
Scientifically it has been shown that chlorophyll fluorescence
(CF) can be used as an effective indicator of seed ripeness: as
the quantity of chlorophyll decreases during seed maturation
ripe seeds contain smaller quantities of chlorophyll than
immature seeds.
During the measurement seeds are
irradiated with a specific wavelength of the light spectrum from
a laser. Chlorophyll emission corresponds with the amount of
chlorophyll present in the seeds. On the screen a graph of the
distribution in seed ripeness will be displayed.
