Other claims from this paper (10)
- Intervention effect Kinetin strongly retarded chlorophyll loss in broccoli leaves.
- Intervention effect Kinetin strongly retarded chlorophyll loss in Xanthium leaves.
- Intervention effect Naphthaleneacetic acid had little effect on chlorophyll loss in Xanthium.
- Intervention effect Concurrent naphthalene acetic acid markedly reduced the kinetin effect.
- Mechanism Interference with kinetin uptake or transport did not appear to explain the reduced effect.
- Association Broccoli young leaves responded to kinetin as much as old leaves.
- Association Naphthaleneacetic acid reduced kinetin effect more in young broccoli leaves than old leaves.
- Mechanism Authors inferred that preventing loss of critical material was more related to kinetin-delayed senescence than mobilization.
- Mechanism Kinetin may control multiple independent events delaying senescence.
- Mechanism Naphthaleneacetic acid may interfere with only one of the kinetin-controlled events.
