| Abstract: | Catechin is associated with several functions in animal and plant systems, with little information available regarding its
role in plant growth. Low concentrations of catechin (50 and 100 μM) were found to enhance length of primary and lateral roots,
number of lateral roots, fresh and dry masses of shoots and roots, leaf area, water potential of leaf and root tissues, the
number of vascular bundles in the inflorescence, and leaf thickness in Arabidopsis thaliana ecotype Col-0. A significant increase in net photosynthetic rate, stomatal conductance and concentration of indole-3-acetic
acid was also observed in catechin treated plants. |
