STRATIFICATION UNNECESSARY FOR GERMINATION OF SEEDS OF STOKES ASTER STOKESIA LAEVIS(J. HILL) GREENE

摘要

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.
