How strict selection of the raw eddy-covariance data influences gpp estimation of a temperate beech forest Inra
Longdoz, B.; Gross, P.; Granier, A..
The data quality and the selection of the correct Eddy Covariance (EC) records become an important step in the CO2 flux determination procedure. An innovative combination of existing assessment tests is used to give a relatively complete evaluation of the net ecosystem exchange measurements. For the 2005 full-leaf season at the Hesse site, the percentage of bad quality data is relatively high (59.6%) especially during night-time (68.9%). This result strengthens the importance of the data gap filling method. The filtering used does not lead to a real improvement of the accuracy of the relationship between the CO2 fluxes and the climatic factors. The soil respiration spatial heterogeneity (on a site with relatively homogenous vegetation pattern)...

Model-assisted analysis of tomato fruit growth in relation to carbon and water fluxes Inra
Liu, H.F.; Génard, M.; Guichard, S.; Bertin, N..
This work proposed a model of tomato growth adapted from the Fishman and Genard model developed to predict carbon and water accumulation in peach fruit. The main adaptations relied on the literature on tomato and mainly concerned: (i) the decrease in cell wall extensibility coefficient during fruit development; (ii) the increase in the membrane reflection coefficient to solute from 0 to 1, which accounted for the switch from symplasmic to apoplasmic phloem unloading, and (iii) the negative influence of the initial fruit weight on the maximum rate of active carbon uptake based on the assumption of higher competition for carbon among cells in large fruits containing more cells. A sensitivity analysis was performed and the model was calibrated and evaluated...
