Transplant shock in stored and unstored 2+0 Douglas-fir seedlings : effect of initial root volume and soil water content

Creator:: Haase, Diane L.
Abstract:: Transplant shock was induced by applying a range of soil water contents to unstored and cold-stored two-yearold (2+0) bareroot Douglas-fir seedlings graded by root volume. Moisture stress had the greatest influence on morphological characteristics commonly associated with transplant shock. Terminal growth, lateral growth, stem diameter growth, and needle length increased...

The influence of ectomyorrhizae on drought tolerance characteristics of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) seedlings

Creator:: Dosskey, Michael G.
Abstract:: Douglas-fir seedlings were inoculated with different species of ectomycorrhizae-forming fungi in order to test the concept that ectomycorrhizae enhance the drought tolerance of seedlings and to investigate the mechanisms responsible for this effect. Seedlings were transplanted at age 6 to 8 weeks into pots containing pasteurized loam soil and inoculated...

The effects of nursery incurred tap-root wounds on growth of Douglas-fir seedlings

Creator:: Whiting, Elizabeth Cameron
Abstract:: Tap-root wounds frequently occur on seedlings during lifting in forest tree nurseries. Data are needed to clarify guidelines for culling wounded seedlings. Two-year-old bareroot Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were wounded by hand on the tap-root to lengths of either 3/8, 1, or 3 inches. Wounded seedlings were used...

Physiological and anatomical studies of several groups of Douglas-fir (pseudotsuga menziesii (Mirb.) Franco) seedlings which demonstrated differential survival potential under drought stress

Creator:: Heiner, Terry Charles, 1941-
Abstract:: Several hundred two year old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were planted in an enclosure designed to permit control of soil moisture. The seedlings came from five seed sources in southern Oregon and one seed source in northwestern Oregon. Mortality terminal and lateral budburst, and soil moisture were recorded...

Responses of Douglas-fir seedlings to various nursery handling and outplanting practices

Creator:: Graff, Joseph Edward
Abstract:: In study 111, four Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stocktypes (1-0, 2-0 standard nursery run and low density bareroot seedlings, and 1 year old container stock) were outplanted in a randomized incomplete block design to an old field in the Willamette Valley of Oregon in a factorial experiment t4 stocktypes...

Impacts of nursery processing on the survival, growth and physiology of 2+0 Douglas-fir seedlings

Creator:: Darbyshire, Robyn Lea Willey
Abstract:: This study compared three nursery handling processes from the time just before lifting to the time seedlings are placed in cold storage after grading, sorting, and packing at the nursery. The seedlings handled in these different ways were compared first in terms of the temperature and plant moisture stresses they...
