National audienceRose plants ( Rosa hybrida cv Sonia) were grown in rockwool in 2 heated greenhouses: 1 control (referred as the low relative humidity (RH) greenhouse) and 1 with RH control (high RH greenhouse). Two electrical conductivity (EC, expressing salinity) rates were applied: high (EC of drainage water around 3.8 mS cm-1) and low (EC of drainage water around 1.8 mS cm-1). In both cases, the drainage rate was kept above 40% of the supplied water. The water potential at stomatal closure (ψfer) and the cuticular transpiration rate (Ecut) were measured throughout the season on phenologically identical leaves. ψfer was not affected by RH or EC. It increased from spring to early fall, recovering partly from early fall to winter. These va...
