Douglas-fir bark : n-hexane-soluble and volatile materials

Creator:: Fang, Henry Hai-loong
Abstract:: Douglas-fir bark was extracted with n-hexane. A light-colored "wax-like" solid was recovered from the extract by evaporation of the solvent. Chemically intact sterol esters and ferulic acid esters were isolated from the "wax" without saponification or degradation as had been necessary in former investigations. The characterization of the intact esters...

Effect of light quality and periodicity upon germination of Douglas-fir seed (Pseudotsuga menziesii (Mirb.) Franco) and on growth of Douglas-fir seedlings

Creator:: Johnson, Le Roy Curtis
Abstract:: A study on the effects of light quality and periodicity on the germination of Douglas-fir seed and the growth of Douglas-fir seedlings was conducted. Interest was focused on responses that could be measured and observed without biochemical assay. It was found that .Douglas-fir seed,s would respond to red-light treatments by...

Ultrastructural study of the embryo during germination involving douglas fir (Pseudotsuga menseizii Franco) seeds

Creator:: Hsu, Kay Yong-Yong
Abstract:: The seeds of Douglas fir, a representative of the gymnosperm flora, were studied at six stages of germination to discern the structures of food reserves and to study ultrastructural changes occurring during germination in the embryo and resulting seedlings. The materials were fixed in three fixatives, dehydrated with ethanol series,...

Within-stem variation of respiration in Pseudotsuga menziesii (Douglas-fir) trees

Creator:: Pruyn, Michele L., Gartner, Barbara L., and Harmon, Mark E.
Abstract:: • A technique for measuring in vitro respiration was investigated to understand why rates were higher than those reported in vivo and to elucidate trends within mature Pseudotsuga menziesii (Douglas‐fir) trees. • Extracted increment cores were divided into 3–4 radial depths and a gas chromatograph was used to compare respiration...

Effect of thinning and fertilization on wood properties and intra-ring characteristics in young Douglas-fir

Creator:: Bodner, Josef
Abstract:: The purpose of this study was to determine if thinning, fertilization or a combination of thinning and fertilization had an effect on overall average specific gravity, modulus of elasticity, modulus of rupture, fiber length and intra-ring characteristics. Material for this experiment consisted of 7 trees randomly selected from each of...

Ultrastructure of parenchyma and sclereids in Douglas-fir [Pseudotsuga menziesii(Mirb.)Franco] bark

Creator:: Dougal, Edward Francis
Abstract:: Because Douglas-fir [Pseudotsuga menziesii(Mirb.)Franco] bark is a raw material produced in our renewable forests along with wood, an understanding of the ultrastructure of bark cells is of paramount importance if wood technologists are to utilize the bark to the fullest potential. The objectives of this study were to develop microscopic...
