Study on relationships among seedling quality and survival rate, stocking percentage and growth

Effects of various seedling classes and root cutting treatments on the survival rate, stocking percentage and the growth of height and collar diameter in young stands of korean pine (Pinus koraiensis), mongolian scots pine (Pinus sylvestris var.mangolica),Dahurian larch (Larix gmelini), korean spruce (Picea koraiensis), anur cork tree(Phellodendron amurensis), manchurian ash (Fradinus mandshurica) and anur linden (Tilia amurensis) were studied in this paper. The results show that the survival rate, stocking percentage and the growth of height and collar diameter of the I class seedlings are better than that of the II and III classes seedlings. So it is very important to select I class seedlings for increasing the quality of afforestation.
