Salinity significantly increased trisodium-8-hydroxy-1,3,6- pyrenetrisulphonic acid (PTS) uptake and decreased the K+/Na + ratio in salt-sensitive rice (Nipponbare) but did not markedly in salt-tolerant rice (Pokkali). Proline and glycinebetaine (betaine) suppressed the increase in PTS uptake and the decrease in the K+/Na+ ratio in Nipponbare, but did not affect PTS uptake or the K+/Na + ratio in Pokkali.
