Role of abscisic acid in regulation of wheat seedling growth under salinity stress

Role of abscisic acid in regulation of wheat seedling growth under salinity stress

Growth of wheat seedlings (Triticum aestivum cv. Mehran-89), in hydroponic culture, was affected by abscisic acid (ABA). Using salinity stress and exogenous ABA application [10*[-6] M] to enhance endogenous ABA level, the growth of roots was more suppressed than the growth of shoots. On the other ha...

Zusammenfassung:Growth of wheat seedlings (Triticum aestivum cv. Mehran-89), in hydroponic culture, was affected by abscisic acid (ABA). Using salinity stress and exogenous ABA application [10*[-6] M] to enhance endogenous ABA level, the growth of roots was more suppressed than the growth of shoots. On the other hand, norflurazon, which inhibitis ABA biosynthesis, reduced only the growth of shoots.
