Other claims from this paper (8)
- Intervention effect Liquid-air treatment did not appear to injure secondary or true leaves of cotton.
- Intervention effect Liquid-air treatment caused double stems and hypocotyls in a large proportion of some flax strains, versus none untreated.
- Observation Other flax strains rarely formed double stems or hypocotyls after liquid-air cooling.
- Association The interval between freezing and planting had little effect on abnormality formation.
- Intervention effect Higher seed moisture before freezing reduced abnormal stems and hypocotyls.
- Intervention effect Freezing in CO2 snow-ether produced abnormalities more effectively than liquid air.
- Intervention effect Seeds at about 10-15 per cent moisture showed no abnormalities after CO2-snow freezing.
- Observation Breeding tests found that freezing-induced abnormalities were not inherited.
