T hrough measuring the morphological and physiological indexes, the optimum concentration of NAA and nutrient solution for the five species of A raceae plants was found out. The results showed that the optimum concentration of NAA for M. obliq ue 耶Dwarf 爷 was 15 mg/L, w hile for other plants was 10 mg/L.
