Abstract: The purpose of the study was to investigate the effects of several factors on rooting of cutting propagation of Picea balfouriana, including cutting types, cutting position, treatment times soaking by water, age of ortets, different individuals and plant hormones. The experimental results showed that there was difference of rooting percentage among different individuals. The rooting percentage of lignified branch was increased by plant hormone treatment, especially treated by IBA 500mg/kg one hour and 200mg/kg five hours respectively, whose rooting percentage were 88.1% and 81.0%. The rooting percentage and rooting number per cutting of young individuals was the same as mature individuals’. There was no different of rooting percentage among different cutting position. Meanwhile, the rooting course at Shangrila of Yunnan province was analyzed, all cutting have callus in 35d after cutting, 45~60d, 90~100d after cutting was the period of higher rooting percentage.
