Other claims from this paper (4)
- Intervention effect Germination of Arabidopsis seeds could be delayed for up to 10 weeks with far-red light treatment.
- Observation Arabidopsis seedlings fixed in KFTs preloaded with glutaraldehyde were not adequately preserved for microscopy.
- Mechanism Poor seedling fixation was suspected to result from extended contact of glutaraldehyde with oxygen during storage on KFTs, which likely contributed to fixative oxidation.
- Method / resource The PVT modifications to the KFT fixation procedure (4 °C dark storage, 5% glutaraldehyde, nitrogen bubbling) improved the quality of microscopic images compared with the SVT procedure.
