dc.description.abstractIn areas with high levels of soil boron, symptoms of boron (B) toxicity often appear under droughts. This greenhouse study examined the interactions of B-toxicity, drought, and genotypes on barley (Hordeum vulgare L.) root growth, B-toxicity symptoms, B concentrations of straw, and yield. Plants were grown in tubes 65 cm tall. Three factors were studied: B, water supply, and genotypes. There were 2 B levels, B0 v. B50, in the subsoil (20-60 cm). There were 4 levels of water supply: no drought (control), and early, mid-season, and terminal drought. Two barley lines were compared: Sahara (B-toxicity tolerant) and BOL (drought tolerant, B-toxicity sensitive). Significant B-by-drought interaction was detected in straw B concentration, root growth in subsoil, and straw and biological yield for BOL. Mean root growth in the 40–60-cm soil section was much higher under mid-season drought than under the control. At B50, plants under drought had 1-fold higher straw B concentrations and more B-toxicity symptoms than the control plants. This is the first study to provide data to explain the frequent association of B-toxicity symptoms with droughts in the field. The results clearly showed that tolerance to B-toxicity, as well as drought, is needed in dry areas having high levels of subsoil B.en_US
