Other claims from this paper (7)
- Intervention effect Culture vessel atmosphere volume strongly influenced pollen embryo induction and growth.
- Intervention effect The optimum frequency of embryo and plantlet producing anthers occurred at 15 ml per anther.
- Intervention effect The optimum plantlet number occurred at 5.5 ml per anther.
- Intervention effect The smallest atmosphere volume nearly eliminated embryo induction.
- Association Ethylene absorption effects depended on atmosphere volume and starting pollen stage.
- Intervention effect Ethylene absorption improved survival of induced embryos from anthers with pollen past first mitosis.
- Intervention effect Three days of silver nitrate treatment did not efficiently increase pollen plantlet yield.
