Emistim C and epibrassinolide improve water exchange, increase drought resistance, productivity of isoplasmic barley lines and of their nucleus- and cytoplasm donors under insufficient water supply conditions were shown. Less phytoregulator – susceptible genotypes have shown the highest resistance to water deficit. Emistim C increased an adaptive potential of barley plants to drought to a greater degree than epibrassinolide. In isoplasmic barley lines directionality of the phytoregulator effect on water exchange parameters depended predominantly on their nuclear genome donors and grain productivity per plant was maximum on the background of their cytoplasm donors
