Seedlings of the salt sensitive wheat cultivar C-306 evolved more ethylene than the salt tolerant cultivar Kharchia-65 under different levels of both chloride- and sulphate-dominated types of salinity. Pre-sowing seed soaking treatments with kinetin, gibberellic acid and to a lesser extent indole-3-acetic acid alleviated salt stress effects as apparent from seedling dry mass. Treated seedlings also evolved more ethylene both under saline and non-saline conditions. Ethrel did not affect seedling growth as well as ethylene production. Abscisic acid inhibited seedling growth and ethylene production under both types of salinity.

Keywords: abscisic acid; chloride-salinity; ethrel; gibberellic acid; indole-3-acetic acid; kinetin; sulphate-salinity
Subjects: abscisic acid, salt stress alleviation; chloride salinity, alleviation of stress; ethylene evolution, ABA; salt stress alleviation, Cl, SO4, growth regulators; sulphate salinity, alleviation of stress; Triticum aestivum; wheat, salt sensitive
