Combined analysis of variance from 2017 to 2018 for catalase, ascorbate peroxidase, peroxidase, superoxide dismutase and polyphenol oxidase enzymes activity, as well as the H₂O₂, malondialdehyde and proline content, membrane stability and grain yield of L. iberica under different irrigation regimes and different concentrations of brassinolide (BR).

S.O.V. = source of variation; Y = year; L.W. = limited watering; B = brassinolide concentration; C.V. = coefficient of variation; df = degree of freedom; CAT = catalase; APX = ascorbate peroxidase; POD = peroxidase; SOD = superoxide dismutase; PPO = polyphenol oxidase; H₂O₂ = hydrogen peroxide content; MDA = malondialdehyde; PRO = proline; MS = membrane stability; and GY = grain yield. ^ns not significant; * significant at 5% probability level; and ** significant at 1% probability level.
