Improving Siberian larch seed germination rates

  • Author(s) / Creator(s)
  • The flotation technique was used to segregate non-viable from viable Siberian larch (Larix Sibirica Ledeb.) seeds using water as the floating media. The non-viable seeds floated while the viable ones sank. Without stratification, the average percent germination of the floating and sunken seeds were 4.2% and 71.0% respectively. Percent germination of the sunken seeds increased from 37.2% before segregation to approximately 70.0% after segregation. Cold stratification for two weeks at 5°C before germination showed no significant difference in the average percent germination between the stratified and unstratified seeds.
