The effect of methanol on quality characteristics of Canola (Hayola 402) under water deficit stress in Varamin region

To study the application of methanol on qualitative and quantitative characteristics under water deficit stress on canola an experiment was conducted as split plot based on RCBD with three replication at research field of Islamic Azad University Varamin branch in 2012. Experimental factors were water deficit stress in main plots (normal irrigation, drought stress at stemming phase, drought stress at pod phase) and methanol (no usage of methanol, spray 14% methanol, spray 28% methanol) as sub plots.Analysis of variance showed significant difference for MDA, DT for simple effect of irrigation, application of methanol and interaction irrigation and application of methanol. Interaction of normal irrigation and 28% methanol increased grain yield and it decreased CAT, MDA and DT. In fact Interaction of normal irrigation and 28% methanolwas the best treatment.In general, application of methanol under water deficit stress decrease oxidative stress destructive effects and it increase qualitative and quantitative characteristics of canola.
