Bert van Duijn is a physiologist and biophysicist, born in Noordwijk aan Zee in the Netherlands. He studied biology/biophysics at Leiden University (cum laude). In 1990 he obtained his Ph.D. from Leiden University (Department of Cell Biology and Department of Physiology) with a study on the role of membrane potential and ions in the chemotactic response of cellular slime molds. Part of the study was done at the Department of Botany of Kyoto University, Japan. After obtaining his Ph.D. he worked as a Post-doc in the Institute of Molecular Plant Science in Leiden on the role of ion fluxes in plant hormone signal transduction. In 1994 he started to work at the Amsterdam University Medical Centre (AMC) on the working mechanism of anaesthetics in cooperation between the Departments of Physiology and Anaesthesiology. By the end of 1996 he returned to Leiden to be part of the management of the Center for Phytotechnology (a cooperation between TNO and Leiden University) and the TNO Department of Applied Plant Sciences. Here, the focus is on Signal Transduction, Medicinal Plants, Seed and Plant Development. Since 15 years the TNO group has been reformed into the Research company Fytagoras BV, at which Bert is the chief scientific officer and member of the management team. Since 2006 he has been involved in teaching at University College Roosevelt and in 2008 he also became professor at Leiden University.  Bert is the Chairman of the “Advanced Technologies Committee” at the International Seed Testing Association (ISTA), and member of the ISTA Rules Committee.


Progress in our understanding of the physiological, molecular and morphological mechanisms and their interactions that determine the performance of seeds greatly relies on the availability of technologies that allow for the investigation of different aspects of seeds under various conditions. Hence, the progress in seed science is strongly related to technical innovations and their availability for application to seed. Digital techniques in combination with completely new technologies and  adapted existing technologies will contribute to new insights in seed science. Specially, non-invasive measurements on a seed allow for combining the obtained data with information of the performance of the same seed in germination and plantlet formation. This makes it possible to directly correlate embryo (and whole seed) status to seed performance. In addition, these technologies may provide tools for improved seed quality testing methods and protocols. In the presentation the basic background of a number of advances in “new” and digital technologies and their application to seeds will be discussed and illustrated. Focus will be on technologies that provide for non-invasive measurements on seeds.
