| Abstract: | Abstract:Melia azedrach leaves extracts through supercritical fluid extract under orthogonal experiment affected the Chinese fir seeds germination differently. Bioassay results revealed: compared with alcohol control, extracts at parameter 1, 4, 7 stimulated the absolute germination rate and potential, radicle growth, plumular axis growth, fresh weight, dry weight at different levels; extracts at parameter 2, 3 stimulated the all germination index except radicle growth and axis growth; extracts at parameter 6 stimulated all but radicle growth and fresh weight; extract at parameter 8 stimulated only the germination potential. Among the three concentrations at the same parameter, extract of 100mg/kg at parameter 1, 4, 5, 7 stimulated the germination most, the following were 50mg/kg and 200mg/kg; extract of 200mg/kg stimulated most , the following were 50mg/kg and 200mg/kg. |
