Title: Juvenility and serial vegetative propagation of Norway spruce clones (Picea abies Karst.).

Author: St. Clair, J.B.; Kleinschmit, J.; Svolba, J.;

Date: 1985

Source: Silvae Genetica. 34(1): 42-48

Publication Series: Miscellaneous Publication

Description: Effects associated with progressive maturation of clones are of greatest concern in clonal tree improvement programs. Serial propagation has been in use at the Lower Saxony Forest Research Institute since 1968 to arrest maturation in Norway spruce clones. By 1980 cuttings were established in the nursery that had been serially propagated from one to five cycles. This material was measured in fall 1983 for several characteristics thought to be indicative of maturation state. Serial propagation appears to have at least considerably slowed, and perhaps arrested, maturation processes in Norway spruce. From a practical point of view, there does not seem to be any restriction for repropagation at least up to the fifth cycle.

Keywords: Picea abies, vegetative propagation, juvenility, maturation
