| Abstract: | In accordance with the datum of the field test and investigation, taking factors analysis regarding Pinue elliotii seedlings as object a preliminary study has been made on quality of seedlings and classifications accordingly. The results are as follows: the factors score y1 and y2 are possibly the clas-sificatory index of Finus ellioltii seedlings, and the seedlings of various classifications have different physiological index. |
