Other claims from this paper (15)
- Intervention effect Photosynthesis of entirely green leaves of oleander was greatly stimulated by high CO2 with no evidence of acclimation
- Intervention effect Photosynthesis of entirely green leaves of willow myrtle was greatly stimulated by high CO2 with no evidence of acclimation
- Intervention effect Dark respiration rates of green oleander leaves were lowered by high CO2
- Intervention effect Dark respiration rates of green willow myrtle leaves were lowered by high CO2
- Intervention effect Yellow portions of willow myrtle leaves had low photosynthetic activity that was stimulated by high CO2
- Intervention effect Dark respiration of yellow willow myrtle leaf portions showed little response to elevated CO2
- Intervention effect Green and yellow areas on variegated willow myrtle leaves had much lower dark respiration rates than completely green leaves
- Intervention effect The dark respiration difference between variegated and green oleander leaves was not evident
- Observation Yellow portions of oleander leaves showed little evidence of photosynthetic capacity
- Observation Yellow portions of oleander leaves had low photochemical efficiency as determined by chlorophyll fluorescence
- Intervention effect Variegation slowed overall plant growth compared with completely green plants
- Association The 3-fold biomass difference between fully green and variegated oleander was closely related to estimated net carbon gain per day by the canopy
- Observation Variegated plants developed about twice the leaf area ratio and specific leaf area of completely green counterparts
- Intervention effect The relative growth response to high CO2 was significantly greater in variegated plants than in completely green plants
- Observation Variegation averaged close to 50:50 green to yellow areas in both species
