#Unit 6. System Physiology – Plant

The treated seedlings show triple response , while untreated grow normally
ethylene response not generated, Both seedling grows normally
treated and untreated both seedlings show radial swelling, elongation of the epicotyl, and horizontal growth of the epicotyl
ethylene treated seedling shows radial swelling, elongation of the epicotyl and fruit ripening while untreated show inhibition of elongation of the epicotyl
