Stratification unnecessary for germination of seeds of stokes aster [Stokesia laevis (J. Hill) Greene]

Lyn A. Gettys, Dennis J. Werner

Abstract


The goal of this study was to determine stratification and temperature requirements for germination of seeds of stokes aster [Stokesia laevis (J. Hill) Green]. No significant differences were noted between seeds that were unstratified and those that were stratified for 15,30,45, or 60 days at 4°C. In addition, no significant differences were found between seeds germinated at 15°C or 20°C after stratification. These data suggest that stratification is not necessary for germination of seeds of stokes aster, and that germination is equally successful at 15°C and 20°C.
