Abstract

  It was found for decades that phytohormones have a prime role in modifying the plant growth. Especially, when these plants are exposed to biotic or abiotic stress. Verify this fact, this study examined the effect of salinity (0.0, 150 and 300 mM of NaCl) with different plant growth regulators (PGR), indole-3-acetic acid (200 ppm IAA) and/or Kinetin (200 ppm KIN). The pre-soaking effects of two plant hormones, IAA and KIN on wheat grains exposed to moderate and high NaCl levels were investigated. According to the results, an increase in salinity caused a progressive decrease in shoot and root lengths, fresh and dry matter yields and the reduction in the compatible compounds chiefly under the highest level of NaCl. While proline content and malondialdehyde (MDA) were increased. Meanwhile, salinity triggered an imbalance in endogenous phytohormones, including KIN and IAA. In our experiment, the application of IAA or KIN or even the combination between them can control the growth processes, improve the salt tolerance of the plant and promote its growth.
