Abstract

Salinity is the most important abiotic stresses adversely affect the quality and quantity of crops, in which 20% of the world's irrigated agricultural lands are affected by salinity. Wheat is an oldest and the first crop used for bread making for human nutrition. To investigate the response of wheat root to NaCl stress, a susceptible, Arta, and resistance, Bam, wheat varieties were grown under both non-stress and stress conditions. Stress plants were exposed to 250 mM of NaCl based on a completely randomized design with four replications. After removing the roots from the soil and removing them from the shoot, the fresh and dry weight, length, volume, Numbers of main roots of each plant were recorded. Then the other roots were harvested and were immediately immersed in liquid nitrogen and stored at -80°C until used for proline measurement.

NaCl stress, proline content, morphological characteristic, root, wheat

Conclusion

We couldn't find significant effect on morphological characters of plants that are under the salt stress due to the short time duration and the effect of stress on morphological trait needs more time. A large number of plant species accumulate proline in response to salinity stress and that accumulation may play a role in defense against salinity stress. Proline content under salt stress is more increase in sensitive cultivar than resistance.
