Other claims from this paper (11)
- Observation An inhibitor occurred in seed coats and embryos of both peach cultivars.
- Observation Inhibitor concentration decreased during stratification.
- Observation Embryos retained more inhibitor than seed coats.
- Association Seed germination increased as inhibitor concentration fell.
- Observation Chromatography tentatively identified the inhibitor as ABA.
- Observation A bound inhibitor was present in both cultivar seed parts.
- Observation Bound inhibitor concentration rose in embryos during stratification.
- Observation High-chilling peach cultivar contained more ABA than the low-chilling cultivar.
- Observation High-chilling peach cultivar contained more bound inhibitor than the low-chilling cultivar.
- Intervention effect Applied ABA reduced germination of stratified seeds without coats.
- Intervention effect Combined GA and BA synergistically promoted dormant seed germination.
