Claim · model-written summary
Low sulfur nutrition was associated with reduced cell wall deposition and consequent lower bulb firmness.
Verbatim
e0“At low S nutrition, which is limiting to the growth of onion bulbs, cell wall deposition is reduced, with a consequent decrease in bulb firmness”

Other claims from this paper (11)
- Intervention effect Onion bulb fresh weight increased as sulfur supply rose from 0.5 to 4.0 meq·L -1.
- Intervention effect Sulfur supply significantly affected onion bulb firmness.
- Intervention effect Onion bulbs at 0.5 meq·L -1 sulfur were significantly softer than bulbs at 4.0 meq·L -1.
- Intervention effect Bulbs at lowest sulfur had significantly less cell wall dry weight than at 3.0 or 4.0 meq·L -1.
- Intervention effect Varying sulfur supply did not affect total onion bulb sulfur.
- Intervention effect Varying sulfur supply did not affect free sulfate in onion bulbs.
- Intervention effect Varying sulfur supply did not affect sulfur content of onion cell contents or cell wall residue.
- Intervention effect Sulfur supply had only a minor effect on onion cell wall proteins.
- Intervention effect Sulfur supply had no significant effect on onion soluble solids concentration.
- Intervention effect Sulfur supply had no significant effect on onion soluble sugars.
- Mechanism Onion cellular sulfur composition was maintained at the expense of bulb growth.
