First year survival and growth of planting stock of various size on adverse sites

Creator:

Chetock, Jerome J.

Abstract:

First year survival of Douglas-fir seedlings outplanted in areas characterized by intense vegetative competition is heavily dependent on available soil moisture. To test this hypothesis, five distinct classes of Douglas-fir planting stock were planted on the south slope of McCulloch Peak in McDonald Forest in February of 1975. The stocking...

Design of an apparatus with controlled rates of temperature change for use in cold tolerance tests of conifers

Creator:

Wessell, William James

Abstract:

An apparatus was designed to permit freezing tests of needles and other tissue parts from coniferous trees under controlled rates of temperature change with time. The design is based on the principle of a balanced system of refrigeration demand and heat input to achieve a steady temperature state. The apparatus...

Root biomass studies of old-growth Douglas-fir

Creator:

Santantonio, Daniel

Abstract:

Root biomass studies were conducted in an old-growth stand of conifers in the western Cascades of Oregon. The root systems of three Douglas-firs (Pseudotsuga menziesii var. menziesii (Mirb. ) Franco) with diameters at breast height of 94, 110, and 135 cm were excavated and weighed to provide a basis for...

Evaluation of the oscilloscope technique for detection of dormancy and survival potential of coniferous seedlings

Creator:

Askren, Catherine Anita

Abstract:

Oscilloscope display of modification of a square wave signal passed through stem tissue was evaluated as a means of detecting depth of dormancy and survival potential of coniferous seedlings. Trace form did not change during release from deep dormancy in Douglas fir. This release was judged by observing speed of...

The long term effects of burning on plant succession

Creator:

Kraemer, James Fred

Abstract:

The succession of plants over a period of 25 years was analyzed on clearcut areas in the western Cascades of Washington and Oregon. Thirty-three paired burned and unburned plots were reexamined in 1975. Data were combined with records from prior examinations by Morris (1970). Cover trends of six major brush...
