leaf abscission is initiated and orchestrated by chaning levels of the plant hormone...... a) auxin b) abscisic acid c) gibberellin c) cytokinin e) ethylene I think it is auxin or absicisic acid. because those of it is talked about hormone. Absicsic acid is plant hormone involved in dormancy and responses to stress . Auxin is a plant hormone involved in various aspects of growth and development. I dont know which one will fix with the question and why?

    Earlier it was though that abscisic acid has a role in it but later it was found that auxins have major role in triggering leaf abscission.
