Other claims from this paper (16)
- Intervention effect Root excision inhibited apical section growth and DNA synthesis.
- Intervention effect Root excision inhibited elongating section growth.
- Intervention effect Synthetic cytokinin restored apical DNA synthesis.
- Intervention effect Low gibberellin concentrations with cytokinin restored apical growth.
- Intervention effect Gibberellin alone restored elongating section growth.
- Intervention effect 5-fluorodeoxyuridine inhibited apical section DNA increase.
- Intervention effect 5-fluorodeoxyuridine did not inhibit control or gibberellin-induced elongating section growth.
- Observation Elongating section DNA labeling did not differ while gibberellin-induced elongation varied 50% to 73% above controls.
- Intervention effect Gibberellin stimulated DNA synthesis in apical tissue apart from elongation.
- Intervention effect Excised hypocotyl elongated maximally at 10(-6)m auxin.
- Intervention effect Higher auxin concentrations increased fresh weight and ethylene production.
- Intervention effect Higher auxin concentrations reduced elongation.
- Intervention effect Adding GA at higher auxin concentrations inhibited auxin-induced ethylene production by 50%.
- Intervention effect GA with higher auxin concentrations restored maximal elongation.
- Intervention effect Added ethylene inhibited elongation 30% at 2 mul/l.
- Intervention effect Up to 100 mul/l ethylene did not inhibit elongation with GA in the medium.
