Other claims from this paper (9)
- Observation Shoot growth continued after excision and shoot length increased considerably before roots emerged.
- Intervention effect Increase in dry weight was strongly dependent on light supply.
- Intervention effect Continued growth was dependent on supply of mineral nutrients to the rooting solution.
- Intervention effect Mineral nutrients had no or slight influence on the number of roots formed on cuttings from stock plants grown in fertilized soil, but the growth in length of the roots was dependent on the presence of calcium in the solution.
- Intervention effect Mineral nutrients had no or slight influence on the number of roots formed on cuttings from stock plants grown in fertilized soil, but the growth in length of the roots was dependent on the presence of calcium in the solution.
- Mechanism Root formation was dependent on photosynthetic products formed after excision.
- Intervention effect No roots were formed on cuttings kept in the dark.
- Intervention effect The number of roots increased with increasing irradiance given to the leafy part of the cutting.
- Intervention effect Light given to the basal part of the cuttings had a strongly inhibitory effect on the number of roots formed.
