|Plants are likely to be affected by simultaneous salinity and boron (B) toxicity stresses due to exposure to soils with high levels of naturally occurring salinity and B, or due to irrigation with water containing high levels of salts, including B. Inadequate information regarding the response of plants to the combination of excess B and salinity on plant growth and yield is available, and there is no consensus concerning mutual relations between salinity stress and B toxicity. Growth and yield of bell pepper (Capsicum annuum L.) were measured at different B and salinity levels in two greenhouse experiments. The results from these experiments and from published data for wheat, tomato and chickpea were analyzed according to the Abbott method to define the combined effect of B and salinity on plant growth and yield. Application of the Abbott method for the experiments on peppers generally implied an antagonistic relationship for excess B and salinity. In other words, toxic effects on growth and yield were less severe for combined B toxicity and salinity than what would be expected if effects of the individual factors were additive. Similar antagonistic characteristics were found using data from three of the five studies reported in the literature. The mechanism of relationships between B and salinity in plants is not clear and several options are discussed. Prominent among the possible explanations are reduced uptake of B in the presence of Cl and reduced uptake of Cl in the presence of B.
