Abstract:
Taking Scutellaria amoena as material,the effects of different concentrations of exogenous melatonin on the callus proliferation and the differentiation of adventitious buds of Scutellaria amoena were studied.The results showed that the supplement of melatonin at 0.1,1.0,10.0 and 100.0 μM in the MS medium remarkeblly improved the frequency of callus proliferation compared with the control (MS medium without melatonin).Same concentration of indole-3-acetic acid (IAA) in the medium exhibited similar effects,but a-naphthalene acetic acid (NAA) did not promote callus growth.Lower concentration (0.1 or 1.0 μM) of melatonin or IAA added in the medium could increase the differentiation frequency of adventitious buds from callus,however higher level of melatonin or IAA inhibited the bud differentiation.
