Other claims from this paper (5)
- Method / resource Inside the chambers the mean air temperature was 1.2 °C higher than outside air.
- Method / resource Inside the chambers the relative humidity was 8% lower than outside air.
- Method / resource Crown photosynthesis of the rubber trees measured in the chamber ranged from 140 to 249 µmol s–1.
- Association Crown photosynthesis was significantly related to photosynthetic photon flux density, total leaf area and average net CO2 assimilation at leaf level.
- Method / resource The 13C labelling efficiency in rubber tree foliage ranged from 43% to 68%.
