基质和生根剂对火力楠扦插生根的影00%peat soil and 65% peat soil+25%raft+10%perlite) and 3 different levels of ABT concentration (800、
500 and 333 mg/kg). The results indicated that substrate type, as well as the rooting agent concentration level
showed significant impacts on the cutting rooting of M. macclurei although these two factors did not interact with
each other significantly; 100% yellow soil was the optimal substrate and the lower ABT concentration was better
than the two higher levels. However, all the 3 rooting agents showed no effect on stimulating the cutting rooting
comparing with the control group which meant exogenous hormone was not necessary and the yellow soil was
effective for the cutting rooting of M. macclurei studied in our research.
Key words　ABT; rooting agent concentration level; yellow soil; cutting propagation; rooting rate
