A DESEEDED AVENA TEST METHOD FOR SMALL AMOUNTS OF AUXIN AND AUXIN PRECURSORS

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.
Mechanism Deseeding prevents physiological aging.
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 An auxin precursor was isolated from the plant.
Observation Precursors of hetero-auxin were demonstrated.

Observation Straight combined wheat had a higher fraction of tough samples than stook or swath combined wheat.
Observation Of straight combined wheat samples, 18% were tough and 7% damp.
Observation Stook threshed samples had 10% tough and none damp.
