The effects of foliar application of methanol on growth and secondary metabolites in lavender
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 2
Abstract
Lavender, known as a medicinal and ornamental plant, is of universal importance mainly because of its high industrial consumptions. With the aim of evaluating the possible impacts of different levels of methanol on the growth and production of secondary metabolites in Lavender plant, the present study was carried out. Plants were foliarly treated with four levels of methanol (0, 10, 20 and 40%) five times with week intervals. the obtained results indicated that the application of methanol affected the photosynthetic pigments. the methanol of 10% and 20% had enhancing effects on chlorophyll contents whereas the observed changes between control and M40 group was not significant. the applied treatments of methanol had improving effects on the plant growth as it was shown with the higher leaf area, leaf fresh and dry mass in methanol treated samples where the most effective treatment was methanol of 20%. the foliarly supplied methanol led to the increased soluble sugar contents in comparison to the control. the promoted production of secondary metabolites, soluble phenolic compounds and essential oil contents, resulted from the application of methanol. The highest used amounts of methanol, 40%, did not have significant desirable effects; therefore it seems that the usage of fewer levels of methanol has better impacts on plant growth and productivity.
