Abstract: 
The leaf cell wall (CW) chemical composition of three maize (Zea mays L.) hybrids (salt-resistant SR 03 and SR 12, salt-sensitive Pioneer 3906) was investigated in the first phase of salt stress (100mm NaCl) compared with the control (1mm NaCl) treatment to investigate whether changes in CW composition were responsible for shoot growth reduction. Salt treatment caused a strong inhibition in shoot growth with a concomitant increase in the ratio between CW dry mass (DM) and shoot fresh mass (FM) and a decrease in CW cellulose concentrations in all hybrids. NaCl caused a large increase in the concentrations of total and non-methylated uronic acid (UA) in salt-sensitive Pioneer 3906 and salt-resistant SR 12. The onset of the accumulation of non-methylated UA was delayed in SR 12, which indicates that this may be one reason for the better growth performance of this hybrid under salt stress compared with Pioneer 3906. It is concluded that a low accumulation of non-methylated UA in leaf CW may, among other mechanisms, contribute to salt resistance in the first phase of salt stress.
