It was shown, that hormonal complex response under stress factor differs in plants organs. It was revealed, that in roots and rhizomes which are directly influenced by oil, there was a simultaneous accumulation of both ABA and IAA. It was observed the increased level of ABA leaves under condition of reduction of IAA content.
