Other claims from this paper (7)
- Intervention effect Late-winter ethephon retarded onion leaf growth.
- Association Bolting inhibition correlated significantly with bulb diameter at treatment.
- Association Bolting inhibition was greatest for bulb diameters of 0.9 to 1.6 cm.
- Observation Bulb diameter in late February or early March effectively predicted ethephon bolting reduction.
- Intervention effect When bolting was greatly reduced, ethephon increased harvestable bulb number and yields.
- Intervention effect When control bolting was low, ethephon decreased yield through lower average bulb weight.
- Intervention effect Ethephon lowered average bulb weight at harvest when control bolting was low.
