We studied the influence of the pretreatment of wheat seedling (Triticum aestivum L.) with 0.4 μM 24-epibrassidinolide (EB) on the growth and hormone status of plants under the influence of 2% NaCl. The pretreatment with EB promoted the lowering of the extent of the damaging influence of salinity on the growth of seedling. The important contribution to the realization of the protective action of EB in the pretreatment of plants is probably that of its ability to lower the level of stress-induced abscisic acid accumulation and the decrease in the content of indole-acetic acid. At the same time, the cytokinin concentration in plants pretreated with EB under salinity was practically the same as in plants without stress. This fact combined with data about the ability of EB to induce the increase in cytokinin content in wheat, obtained before, allowed us to assume that the protective action of EB on plants is connected, first of all, with the prevention of the decrease in level of hormones of cytokinin nature under salinity. © Pleiades Publishing, Inc., 2010.
