Other claims from this paper (6)
- Mechanism The diffuse centromeric chromosome organisation of Cyperus eragrostis leads to inviable chromosome complements after seed irradiation.
- Observation After seed irradiation, complex configurations and numerous fragments persist to pollen grain formation in Cyperus eragrostis.
- Intervention effect At lower irradiation doses Cyperus eragrostis had low fertility.
- Observation M2 and M3 plants from lower irradiation doses showed reduced chromosomal abnormalities.
- Mechanism Severe selection among gametes and zygotes explains the reduced chromosomal abnormalities in M2 and M3 plants.
- Mechanism The diffuse centromere gives little advantage in survival from radiation damage in Cyperus eragrostis.
