Fig. 1.

Diagram representing the ORYZA v3 model and the flow of mass and information between its different modules. The tied boxes represent process rates; the boxes represent state variables, and the circles, the intermediate variables. The dashed lines represent flow of information and the continuous lines represent flow of mass. The black lines and text indicated the processes which representation was modified with the new functions accounting for the salinity effect. LAI, leaf area index; N, nitrogen. (a)–(c) indicated the processes affected by the salinity effect namely soil solute content changing soil osmotic potential component and soil water tension (a), transpiration rate (b) and leaf photosynthesis (c).
