Other claims from this paper (14)
- Intervention effect IAA stimulated Avena coleoptile base growth.
- Intervention effect Combined GA and IAA stimulation of coleoptile base growth was less than additive, without synergy.
- Intervention effect GA greatly stimulated first-leaf base growth.
- Intervention effect IAA inhibited first-leaf base growth.
- Intervention effect Low IAA concentrations nearly eliminated GA stimulation of first-leaf base growth.
- Intervention effect Including first internode tissue increased first-leaf base growth.
- Intervention effect Including first internode tissue had no consistent effect on coleoptile base growth.
- Intervention effect First internode tissue greatly increased GA stimulation of first-leaf base growth.
- Intervention effect First internode tissue did not influence the degree of IAA inhibition.
- Mechanism The authors propose an unknown growth factor from first internode tissue as necessary for GA action in the first leaf.
- Intervention effect The tested named compounds did not reproduce the proposed growth-factor effect in leaf tissue.
- Intervention effect Kinetin virtually eliminated GA stimulation of leaf growth.
- Observation First-internode extracts showed growth inhibitors and gibberellin-like substances.
- Observation The extraction and chromatography study did not isolate the postulated endogenous GA synergist.
