Parameters affecting shoot production and its rooting of cuttings from lodgepole pine hedges
New Forests: 1996 12:101-111
Abstract
By propagating lodgepole pine (Pinus contorta) cuttings in vivo,
we obtained after 7 growing cycles (ca 3.5 years) in a greenhouse,
sufficient number of cuttings from most families to establish clonal
progeny tests. Twenty-one full-sib families with approximately 20
clones per family were studied for five years. Years when cuttings were
set, families within latitude and clones within families differed
significantly in rooting percentages, with the variance components
4.2%, 8.2% and 9.5%, respectively. One way to get a frequent and
uniform rooting is to take cuttings from non-leading shoots since they
have higher rooting percentage than leading shoots. Neither total
length of the cuttings nor length of the primary needles were
significantly correlated to rooting percentage. With appropriate
management of the ortets and the cuttings during rooting, most clones
could be included in a cutting propagation program.
