Other claims from this paper (8)
- Association In light, kinetin-treated cotyledons had lower paramagnetic manganese and enhanced IAA oxidase activity.
- Association Paramagnetic manganese level was inversely correlated with IAA oxidase activity.
- Association In darkness, manganese and IAA oxidase activity did not have the correlation observed in light.
- Intervention effect Kinetin stimulated peroxidase activity in both light and darkness.
- Mechanism The authors infer that peroxidase brings about IAA oxidation in dark-grown kinetin-treated cotyledons.
- Mechanism IAA oxidation appears mediated by peroxidase and manganese in light but by peroxidase alone in darkness.
- Mechanism Increased IAA oxidase activity during kinetin-induced cotyledon growth is incompatible with auxin limitation by that activity.
- Mechanism Kinetin removed the inhibitory effect of light on IAA oxidase activity, possibly through synthesis of activators.
