ALLEVIATION OF SALT STRESS BY PLANT-GROWTH REGULATORS IN TRITICUM-AESTIVUM L

Seedlings of the salt sensitive wheat cultivar C-306 evolved more ethy lene than the salt tolerant cultivar Kharchia-65 under different level s of both chloride-and sulphate-dominated types of salinity. Pre-sowin g seed soaking treatments with kinetin, gibberellic acid and to a less er extent indole-3-acetic acid alleviated salt stress effects as appar ent from seedling dry mass. Treated seedlings also evolved more ethyle ne both under saline and non-saline conditions. Ethrel did not affect seedling growth as well as ethylene production. Abscisic acid inhibite d seedling growth and ethylene production under both types of salinity .
