pass through (in order)
Growth may be stimulated in lateral buds If the terminal bud is removed in pruning:
The growth rings of a tree: Visible because of the rapid growth rate of earlywood relative to latewood,
can be counted on to approximate trees age, can give information about
growth conditions in previous years.
Cambium layer of cells is responsible for outward growth and increased girth of tree.
Mycorrhizae are: A symbiotic relationship between fungi and roots.
Douglas-fir (Pseudotsuga menziesii) differs from balsam They are not in the same genus.

Opposite leaf arrangement is: When two leaves and/or buds are located at the same node on a twig.
Quercus rubra Scientific name of Red Oak.

Water will drain very slowly out of the planting hole. If a planting hole in a clay soil site is backfilled with sandy soil.
When soil is compacted: Total pore space and the percentage of macropores are reduced.
A characteristic of sandy soils in arid regions is: They tend to become alkaline, and salts build up due to the lack of heavy
rainfall.
When irrigating trees: Infrequent, deep soakings are preferable to frequent, shallow waterings.
Sandy soils: Have a higher infiltration rate than clay soils.
A soil is at field capacity when: Gravitational water has drained away.
With sprinkler irrigation: Less frequent waterings of longer duration will reduce the likelihood of salt
buildup, water hitting the soil surface can lead to crusting, application rates
that exceed absorption can lead to runoff.
In sites where poor drainage can be a problem, which Placing gravel in the bottom of the planting hole and backfilling with a sandy
