Other claims from this paper (11)
- Intervention effect BAP inhibited lateral root elongation and formation.
- Intervention effect BAP stimulated swelling of root tips.
- Intervention effect Zeatin produced similar root growth effects.
- Observation Root growth effects occurred at concentrations down to 0.01 μ M.
- Observation Growth responses appeared after several hours of treatment and depended on treatment duration.
- Intervention effect BAP moderately increased ethylene production in root tips.
- Intervention effect Cobalt ions counteracted BAP-induced root inhibition and swelling.
- Intervention effect Silver ions partly reversed the BAP response.
- Mechanism The BAP-induced ethylene increase was too low to explain the root response.
- Intervention effect ACC lowered IAA content in root tips.
- Intervention effect BAP increased the amount of IAA per root tip.
