It was found that spermidine (5mM) delivered to wheat seedlings through their roots prior to water stress affected the state of polysomes and ribosomes under water stress conditions, which was manifested in stabilization of 80 S ribosomes and in reduction of polysome fraction. Besides, it was observed that pretreatement with spermidine decreases RNase activity in plants exposed to water stress
