Cutting Propagation of Picea koraiensis and Picea koraiensis var. nenjiangensis
With the outside net-house system,the softwood cutting propagation of Picea.koraiensis Nakai var.nenjiangensis and P.koraiensis at different ages were conducted.The mean rooting percentage of P.koraiensis Nakai var.nenjiangensis was 27.9％ and the mean number of adventitious roots were 6.2.The mean number of adventitious roots between Picea.koraiensis Nakai var.nenjiangensis and P.koraiensis were not significant.However,the rooting percentage of cutting from saplings of 40-59 a was significant compared with P.koraiensis,but it was not significant from saplings of 60-99 a.The result showed that the cuttings of P.koraiensis Nakai var.nenjiangensis presented significant age effect.
