The aim of this investigation was to improve salt tolerance abilities prior to rice crop harvesting, including proline accumulation, pigment stabilization, water use efficiency (WUE), photosynthetic efficiency, and growth, by using exogenous foliar-sprayed glycinebetaine (Glybet). Pathumthani 1 (PT1) is reported to be a salt-sensitive cultivar and it was selected as a model plant. The proline content of PT1 rice was enriched by 50 mM of foliar-sprayed Glybet, thereby maintaining WUE and pigment stabilization, leading to high photosynthetic performance in chlorophyll a fluorescence and CO_2 assimilation, and increasing plant height when the plant was exposed to 150 mM of NaCl salt …
