Adventitious roots were induced from 2-month-old young leaves of In vitro grown plantlets of Morinda citrifoli on Murashige and Skoog (MS) medium supplemented with 1 mg l-1 IBA. Among the different concentrations of indole-3-butyric acid (IBA) and -napthaleneacetic acid (NAA) tested, 1 mg l-1 IBA was proven as the best auxin source for adventitious root induction under fluorescent light. Accumulation of hydrogen peroxide (H2O2) in induced root under different light showed a positive correlation with peroxidation of lipids and was observed higher under far-red followed by red plus blue light....
