and season
All seedlings are susceptible to
salt injury to some degree. Germinants
and young seedlings are
particularly vulnerable because of
their succulent nature, whereas
older seedlings and other stock
types, such as transplants, are more
tolerant. Small-seeded or slowgrowing
species like spruces and
firs are often more susceptible
because they take longer to grow
out of the young, succulent stage.
Whereas the salt tolerance of
most agronomic crops has been established,
that of many species of
Pacific Northwest forest tree seedlings
has never been determined.
Most commercially produced
nursery stock should be considered
susceptible, however. Pine seed
