Being the most abundant element on earth, aluminium has become one of the major restricting factors that affect the growth and development of plants. The first target of aluminium toxicity is the root apex which would in turn affect the overall growth of the plants. In this study, the effect of various concentrations of aluminium (Al) on the growth of Lobelia chinensis was determined. Nodal explants of L. chinensis were cultured on MS medium containing various concentrations of aluminium chloride (AlCl3) (0, 1.0, 2.5, 5.0, 7.5, 10.0 and 20 µM) with 1250.0 μM ion phosphate and pH was adjusted to 4.6. It was observed that both the growth of shoot and root decreased with the increasing concentrations of Al.
