Abstracts:Used Phoebe boarnei and Phoebe zhennan as experimental materials,We studied the effects of different concentrations of 1 naphthyl acetic acid on transplant one year old seedlings of Phoebe boarnei and Phoebe zhennan in light matrix containers. The results showed that when the seedlings of Phoebe zhennan treated at the 1 NAA concentration of 100 mg/L,their survival rates which was 64% was the highest; when the seedlings of Phoebe zhennan treated at the 1 NAA concentration of 200 mg/L, their young leaves germination rate which was 24% was the highest; The average growth amount of Phoebe boarnei sprouts and new leaves increased with the increasing of the concentration of 1 NAA and the amount reached the highest at the concentration of 400 mg/L,The average growth amount of Phoebe zhennan sprouts and new leaves increased with the increasing of the concentration of 1 NAA and the amount reached the highest at the concentration of 400 mg/L.
