The aim of this study id analysis the effect of methanol foliar application on the physiological traits of beans genotype under water deficit stress as a split plot design was conducted in a randomized complete block design in Safiabad Dezful Agricultural Research and Natural Resources and Center in 2018 and 2019 years. Water deficit stress was the main plots include four levels (25, 50, 75 and 100% of plant water requirement) and combined foliar aplication of methanol including 3 levels (control, 10 and 20%) and genotype treatment including two cultivars omidbakhsh 1057 And Mashhad was in sub-plots. The results showed that the interaction of water deficit stress and foliar application of methanol on ion leakage, chlorophyll a, carotenoids, leaf soluble carbohydrates and proline grains was significant at the 1% probability level. The lowest amount of ionic leakage observed under the interaction of 100% water deficit stress and 10% foliar aplication of methanol (25/23 μmos/cm) and The highest amount of ion leakage under the interaction of 25% water deficit stress and the without foliar aplication of methanol (control) (42.25 μmos/cm). The highest amount of chlorophyll a was observed in line 1057 under the 100% water deficit stress and 20% foliar aplication of methanol (0.19 µmol.g-1 FW). The highest concentration of carotenoids in line 1057 under the treatment of 100% water deficit stress (0.19 µmol.g-1 FW) and the highest amount of soluble carbohydrates under the treatment of 100% water deficit stress and 20% foliar aplication of methanol (50.83 µmol.g-1 FW) was observed.
