Seed X-ray. Seeds being X-rayed at the Millennium Seed Bank,Wakehurst Place,Sussex,UK. The X-ray will reveal seeds that are infected with pests or diseases. It is also used to analyse the embryo and endosperm content,which affects germinating viability. The Millennium Seed Bank Project is an international effort aimed at safeguarding seeds from 30,000 species,representing 10 percent of all the world's flowering plants. Seeds arriving at the seed bank are checked for pests,diseases and viability using X-rays and germination tests. The seeds are then stored at minus 20 degrees Celsius. In 2007 the seed bank contained seeds from over 18,000 species spanning 126 countries,making it the largest wild seed collection in the world |
