Description
Summary:The responses in terms of seedling growth, biomass allocation and photosynthesis of Nouelia insignis Franch. and Terminalia franchetii Gagnep. to long‐term water stress were studied in a greenhouse experiment. Three‐month‐old seedlings were subjected to the following water supplies for about 79 days: 80, 60, 40 and 20% of field water capacity (FC). The results showed that, as water stress was increased, seedling height, leaf number, root length, specific leaf area (SLA), biomass production and stomatal limitation value (Ls) of both seedlings decreased, and water use efficiency (WUE) increased, and biomass allocation, the diurnal gas exchange and Pn‐PAR response curves also altered.
