| Leyland cypress, laurel oak and slash pine were grown for
18 months in plastic containers, in fabric containers or directly in the
field and then transplanted into field soil. There was no difference in
growth between field-grown and fabric container-grown trees for laurel oak
or slash pine, but field-grown Leyland cypress were taller than fabric container-grown
trees. Container-grown trees were smallest for all three species. Shoot:
root dry weight ratio was smallest on container-grown trees because little
of the root system is lost during transplanting compared to fabric and field-grown
trees. Ten weeks after transplanting, weight of regenerated roots on fabric
container-grown Leyland cypress and slash pine was greater than on field-grown
trees. Field-grown slash pine regenerated less root weight than trees produced
by other production methods. Production method did not affect root regeneration
of laurel oak. |
