Sibelle Santanna is a PhD student from the Universidade de Sao Paulo in Brazil. She studies seed physiology at the Escola Superior de Agricultura Luiz de Queiroz in Piracicaba. Sibelle will spend 9 months at he OPGC assessing seed quality in different species of Phlox. The research will focus on comparisons of tests for seed viability such as germination and tetrazolium chloride; it will also examine seed dormancy and methods to efficiently overcome it for rapid germination.
