To investigate the effect of soaking with chitosan and proline levels under salinity stress on seedlings characters of wheat, a laboratory experiment was carried out at Central Laboratories in Central Administration for Seed Testing and Certification, Ministry of Agriculture, Egypt, during January 2019. The experiment was conducted in factorial experiment in randomized complete block design (RCBD) with four replications. The first factor included four levels of soaking with chitosan (0.00, 0.25, 0.50 and 0.75%). The second factor integrated with five levels of soaking with proline (0, 1, 5, 9 and 13mM). The third factor incorporated with four levels of salinity i.e. 0, 4, 8 and 12dSm-1 of NaCl. The results indicated that soaking in chitosan at 0.75% recorded highest values of seedlings characters, followed by soaking in chitosan at 0.50%. The highest values of seedlings characters were produced from soaking in highest level of proline (13mM), followed soaking in proline at 9mM. The highest values of seedlings characters were obtained from the control treatment (without salinity stress), followed by salinity stress at the level of 4dSm-1 of NaCl and then salinity stress at the level of 8dSm-1 of NaCl. It could be concluded that for maximizing seedlings characters of bread wheat Shandaweel 1 cultivar under salinity stress, it could be recommended to soaking with the mixture of chitosan at the rate of 0.75 or 0.50% and proline at the rates of 13 or 9mM for 6 h.
