Effect of Cinnamic Acid on Physiological Characteristics of Tomato Seedlings and Alleviation by Carbonized Maize Cob Application

doi:10.3969/j.issn.1000-7091.2012.05.027

Abstract

Abstract: We examined the effects of cinnamic acid on the growth of tomato seedlings,and its alleviation of applied carbonized maize cob was shown.The tomato seedlings were transplanted in the hydroponic system with perlite as substrate,and the biomass,photosynthesis,ultrastructure of root and MDA were investigated.The results showed that cinnamic acid inhibited the biomass,photosynthesis and chlorophyll contents of tomato seedlings.Deformation of the ultrastructures of root was observed and the MDA content was increased by the treatment of high content cinnamic acid.But the inhabitations were alleviated by applied carbonized maize cob.Carbonized corn cob can be used to prevent the plants from monocropping obstacles.

Key words: Cinnamic acid, Tomato, Autotoxicity, Photosynthesis, Ultrastructure, MDA Carbonized maize cob
