Verbatim
e0“The auxin content (extractable and ‘diffusible’ auxin) of non‐sterile corn plants is much more increased by a tryptophan application than the auxin content of sterile plants”
e2“The epiphytic bacteria settling the shoot surface are responsible for this effect, since in special experiments the rhizosphere was separated from the tryptophan treatment”

Other claims from this paper (4)
- Intervention effect Tryptophan application much more increased the auxin content of non-sterile corn plants than that of sterile corn plants.
- Intervention effect The tryptophan effect on corn auxin content is independent of whether tryptophan is sprayed or supplied with the transpiration stream.
- Intervention effect Sterilized corn plants reinfected with epiphytic IAA-producing bacteria behave like non-sterile plants.
- Intervention effect Non-sterile corn plants superinfected with these bacteria strains have a still higher capacity to convert tryptophan to auxin.
