The importance of maintenance respiration by living cells in the sapwood of subalpine conifers

Creator:

Ryan, Michael G.

Abstract:

Xylem conducting tissue or sapwood is an important storage organ for water, carbohydrates, and nutrients, and this storage helps trees accommodate environmental change. However, the living ray parenchyma cells in sapwood, which store the carbohydrates and nutrients, require energy for maintenance. I examined how sapwood maintenance costs vary among species,...

The estimation and significance of sapwood basal area in young Douglas-fir stands

Creator:

Dolan, Linda Sutliff

Abstract:

The relationship of sapwood basal area to basal area was examined on stands of young-growth Douglas-fir. Through non-destructive sampling, sapwood basal area was quantified on four different thinning intensities and one control (unthinned) treatment. Emphasis was on testing a sampling method and evaluating variations in the sapwood component as a...

Xylem cavitation in newly planted western hemlock (Tsuga heterophylla (Raf.) Sarg.) seedlings

Creator:

Kavanagh, Kathleen L., 1955-

Abstract:

Reforestation of Pacific Northwest forest-lands with western hemlock has been hindered by unexplained plantation failures. The purpose of this thesis is to provide information that will help in determining the cause of seedling damage and mortality. The studies focused on the relationship between xylem water potential, xylem cavitation and the...

Xylem discontinuity in Vitis vinifera L. berries

Creator:

Creasy, Glen L.

Abstract:

Several effects of xylem discontinuity in Pinot noir and Merlot grape berries were studied. There was a reduction in the amount of apoplastic dye (Eosin Y or azosulfamide) uptake through cut pedicels into soft versus firm berries, suggesting a reduction in maximal xylem flow at that time. Both greenhouse and...
