Studies on The Physiology of Dwarfism in Wheat: IV Effect of Gibbereslli Acid on Protein Metabolism

Further investigations into the physiology of dwarfism in wheat, revealed that GA₃ stimulated protease activity was observed only in those vari-ties which showed enhanced growth viz. G-306, Sonalika and Kalyansana, Increased proteolysis caused reduction in protein nitrogen. Changes in protease activity and protein nitrogen were not proportional to seedling age. The total nitrogen was practically unaffected by either gibberellic acid or seedling age. The triple dwarf Moti failed to respond to GA₃ in any of these attributes.
