Other claims from this paper (11)
- Intervention effect Begonia × cheimantha grown in full sun was more compact than plants grown under shade.
- Intervention effect Begonia × cheimantha grown in full sun flowered earlier than plants grown under shade.
- Intervention effect Begonia × cheimantha grown in full sun had shorter peduncles than plants grown under shade.
- Intervention effect Begonia × cheimantha grown in full sun had more flowers than plants grown under shade.
- Intervention effect Reducing the vegetative long-day period from 7 to 4 weeks had no effect on leaf damage in Begonia × cheimantha.
- Intervention effect Paclobutrazol-treated Begonia × cheimantha plants were shorter than untreated plants.
- Intervention effect Paclobutrazol reduced leaf damage in Begonia × cheimantha compared with untreated plants.
- Association Leaves of paclobutrazol-treated Begonia × cheimantha had a higher concentration of soluble protein and chlorophyll than untreated plants.
- Association Leaves of paclobutrazol-treated Begonia × cheimantha had enhanced activities of ascorbate peroxidase, DHA reductase and MDHA reductase compared with untreated plants.
- Recommendation Begonia × cheimantha should be grown under reduced light intensities.
- Recommendation Excessive height and leaf damage in Begonia × cheimantha should be controlled with growth retardants such as paclobutrazol.
