O Criador:: White, Timothy L., 1951-
Abstract:: This thesis is divided into three chapters. For all chapters, the experiments described deal with the responses of all or a subset of 72 wind-pollinated Douglas-fir families from 36 different locations in southwestern Oregon. Wind-pollinated seed was collected from each of two trees at each of the 36 locations. The...

O Criador:: Stevens, Roderick D.
Abstract:: From a preliminary 1969 foliar analysis, eight provenances were chosen from the sixteen included in a region-wide, reciprocal Doulgas-fir provenance study for further study of variation in foliar nutrition. In the fall of 1969 separate foliar samples were collected from ten trees per provenance at each of ten plantations ranging...

O Criador:: Griffin, Anthony Roderick
Abstract:: A sample of 181 wind pollinated families, representative of the range of environmental conditions occupied by Douglas-fir in northern California, was used as a basis for studying variation in early height growth, phonology, and seed characteristics. Seedlings were raised at Corvallis, Oregon, in a nursery trial designed to evaluate response...

O Criador:: Yang, Jenq-chuan
Abstract:: Genetic variability in natural populations of Douglas-fir was studied at molecular level by investigating the variations of some primary gene products, i. e. enzymes. Using the techniques of disc gel electrophoresis and biochemical staining, the isoenzyme patterns of leucine aminopeptidase, esterase and glutamate oxaloacetate transaminase are characterized in young seedlings...
