Abstract:: Taking 10，15，20，25，30，35，40，45，50 cm Dracaena sanderiana ‘Virens’ seedlings as materials，the effect of IBA treatment incision and 9 different lengths of seedlings on rooting and seedling etiolation were studied.The results showed that root fresh weight of seedling with IBA treatment reached significant differences compared to water;root number，root diameter，root length，root fresh weight，root dry weight，percentages of the whole leaves yellowing，half leaves yellowing and <3 cm yellowing leaves per plant of 9 different length of seedlings reached significant or very significant differences;Seedling length was highly significantly positively correlated to root number，root length，root fresh weight，root dry weight per plant，percentage of the whole leaves yellowing per plant，respectively.Taking into account the seedlings root number and seedling etiolation rates and cost，incision treated with 10 mg/L IBA for 24 hours and 30 and 35 cm length seedlings were the best.
