Abstract：Root-cut-grafting seedlings of cucumber（Cucumis sativus L.）were used as material，
the scions were treated with 5 concentrations of NAA solution. Through measuring seedlings indexes，
namely：survival rate，morphological parameter，vigor indexes，root activities etc，the effects of 5
NAA concentrations on the quality of root-cut-grafting seedlings were studied．The results showed that
the survival rate of grafting had been raised by NAA treatment，it could reach up to 94% for 40 mg·L-1
NAA concentration．The quality of seedlings increased at first and then decreased with increasing
concentration of NAA solution during a certain range of 0-50 mg·L-1 concentration．When the
concentration reached 40 mg·L-1，all kinds of morphological and physiological indices had the best
performance．In conclusion，40 mg·L-1 NAA treatment could effectively promote the growth of
cucumber root-cut-grafting seedlings and improve their quality.
