Other claims from this paper (9)
- Intervention effect September-sown sugar beet intercepted 40% of radiation since mid-April, compared with 28% for October and 9% for April sowing.
- Intervention effect Autumn-sown plants were 20 fold heavier than spring-sown plants by early June, but the advantage declined with bolting.
- Mechanism Root growth slowed when assimilates were diverted to stem and inflorescence growth.
- Intervention effect Delaying autumn sowing from late September to mid-October delayed and reduced bolting frequency.
- Intervention effect Frequent cutting of bolting inflorescences improved root growth in bolters and non-bolters.
- Intervention effect Ethephon at 10000 mg a.i./l severely checked sugar beet growth and killed 55% of plants.
- Intervention effect Among surviving ethephon-treated sugar beet plants, 25–30% fewer bolted than untreated plants.
- Intervention effect Ethephon treatment reduced yield by 26–42%.
- Intervention effect Less concentrated ethephon doses did not affect bolting.
