Web12 de abr. de 2024 · On day 10, salinity stress was introduced by using 150 mM salted water. Typically, under high-salt conditions, the transpiration of the plant would be reduced because of the reduction of water absorption from roots as a result of the osmotic pressure difference between soil and root . Web21 de abr. de 2024 · Most studies with plants growing in concentrations of NaCl above 100 mM find that Na + and Cl – increases in roots are only 50–65% of that needed for osmotic adjustment and only at 50 mM NaCl do the increases in ions provide 90% of the osmotic adjustment (Fig. 2; Table S3 ).

"WebOsmotic pressure is defined as the measure of the tendency of a solution to take in pure solvent. It is maximum in halophytes as they have high concentration of salt thus they have large number of solutes which makes the solution osmotically active and increases the osmotic pressure.
