Other claims from this paper (13)
- Association Intercellular CO2 concentration (Ci) gradually decreased with increasing light intensity in both Hevea clones.
- Observation The highest leaf-air vapour pressure deficit was in leaves of the upper canopy.
- Observation The lowest leaf-air vapour pressure deficit was in the bottom canopy layer.
- Observation Water use efficiency of clone RRISL 211 was higher than that of clone RRIC 121 under tapping.
- Mechanism The higher WUE of RRISL 211 was attributed to its greater photosynthetic rates rather than lower transpiration rates.
- Association CO2 assimilation rate (A) was highly significantly correlated with gs.
- Association CO2 assimilation rate (A) was highly significantly correlated with Tr.
- Association CO2 assimilation rate (A) was highly significantly correlated with intensity of PAR.
- Association There was no correlation between PAR and WUE, so WUE remains approximately constant as PAR increases.
- Intervention effect In tapped treatments, tapping stimulated the photosynthetic rate relative to the transpiration rate.
- Association Latex yield responded positively to WUE and lvpd of top leaves.
- Association Latex yield had a negative correlation with gs.
- Mechanism In top leaves, reduced Ci increases the CO2 gradient and CO2 uptake for more photosynthesis, which increases latex yield.
