X-Ray Vision!

Becky x-rayNorthwestern Ph.D. students Rebecca Tonietto and Paul Hartzog have been using our new X-Ray set-up to determine seed viability of all collections that are currently being accessioned into the seed bank. X-ray vision allows us to see if the embryos inside the seed are fully mature, or if there are insect larvae feasting on our precious seed.
