Title
A DESEEDED AVENA TEST METHOD FOR SMALL AMOUNTS OF AUXIN AND AUXIN PRECURSORS
Folke Skoog The Journal of General Physiology 1937. doi:10.1085/jgp.20.3.311
Other claims from this paper (10)
- Method / resource The deseeded Avena method quantifies about ten times lower hormone concentrations than the standard method.
- Mechanism Longer assay time allows nearly all applied hormone to be utilized.
- Observation Deseeded plants have increased sensitivity to unilaterally applied low hormone concentrations.
- Mechanism Deseeding prevents auxin regeneration by removing material for auxin synthesis.
- Observation Auxin synthesis in the coleoptile tip and regeneration in the new physiological tip have identical mechanisms.
- Method / resource The deseeded method measured auxin in Avena primary leaves and coleoptile sections.
- Method / resource The deseeded method distinguishes auxins from substances activated by plants.
- Observation Reduced auxin synthesis in deseeded plants indirectly supports an auxin precursor.
- Observation An auxin precursor was isolated from the plant.
- Observation Precursors of hetero-auxin were demonstrated.
