Abstract: In order to obtain high quality seedlings of Araucaria cunninghamii, the seeds were collected from 30—60 year-old robust mature trees. At the seedling stage, watering, fertilization, diseases and pests control were paid great attention. With the seedling height, root length and the ground diameter as the indexes, the 1-year-old and 2-year-old seedlings of A. cunninghamii were divided into three quality classes using the SPSS K-means clustering. The height and the ground diameter of the 1-year-old seedlings and third class of 2-year-old seedlings were too short to be outplanting. The first and second classes of the 2-year-old seedlings were suggested to be outplanting.
