Other claims from this paper (5)
- Observation The 40% CuSO 4 and water filters had similar narrow band R:FR ratios.
- Observation The broad band R:FR ratio of the 40% CuSO 4 filter exceeded that of water.
- Observation Estimated phytochrome photoequilibrium was similar under water and 40% CuSO 4 filters.
- Intervention effect CuSO 4 chambers reduced final chrysanthemum height by about 30% relative to control chambers.
- Association Broad band R:FR correlated more closely with plant response than narrow band R:FR.
