Other claims from this paper (6)
- Intervention effect Co(2+) promoted elongation of light-grown cucumber hypocotyl segments.
- Intervention effect Blocking auxin transport at cotyledon bases eliminated Co(2+) growth promotion.
- Intervention effect Co(2+) prevented lateral swelling from supraoptimal IAA.
- Intervention effect Removing ethylene reduced the Co(2+) response.
- Intervention effect Co(2+) did not counteract inhibition by increased ethylene.
- Intervention effect At growth-promoting concentrations Co(2+) inhibited ethylene production in cucumber hypocotyl.
