| Abstract: | The cuttings from 3-year-old mother plant of Picea pungens were chosen to investigate their rooting ability and the optimized combination of rooting agent.Besides,the effect of different cutting conditions on the rooting of different varieties of P.pungens was studied systematically.The results showed that the callus formation of P.pungens cutting started at10 days after cutting,and after 30 days they began to root,and the peak period of rooting was 4070 days after cutting,and 80 days after cutting the root... |
| Keywords: | Picea pungens variety cutting condition rooting process rooting rate |
