Wool from Merino sheep is an important component of the Australian economy. However, little is known of the mechanisms within the wool follicle that regulate fibre production. The aim of the research described here was to identify and characterise some of the genes expressed in the follicle.A highly expressed gene has been identified from skin and sequenced. The information obtained on this gene suggests that it might be of use in future transgenic studies. Two cDNA libraries were constructed.

[Truncated abstract] The core objective of this thesis is summarised by its title: “Understanding the World Wool Market: Trade, Productivity and Grower Incomes”. Thus, we wish to aid understanding of the economic mechanisms by which the world wool market operates. In doing so, we analyse two issues trade and productivity and their effect on, inter alia, grower incomes. To achieve the objective, we develop a novel analytical framework, or model. The model combines two long and rich modelling traditions: the partial-equilibrium commodity-specific approach and the computable-general-equilibrium

The transition from old-growth to second-growth British Columbia coastal Douglas-fir has resulted in reduction of log size and increased proportion of juvenile (core or crown-formed) wood. Determination of the zone of transition from juvenile to mature wood is critical to the definition of wood quality and timber value. Thirteen unpruned, two pruned second-growth, and two unpruned plantation-grown coastal Douglas-fir trees were sampled to analyze the hypothesis that the transition in relative density from juvenile to mature wood occurs at the base of the live crown.

Trembling aspen (Populus tremuloides Michx) is Canada’s most abundant poplar species; it is native, found nationwide, and is an ecologically and economically important hardwood species. As the demand for raw material continues to rapidly increase, there is an incentive to improve tree quality and growth rates through breeding, particularly in fast-growing species suitable for the Canadian landscape. Hybridization is considered one of the best options to accelerate tree productivity and improve wood quality. Two aspen species showing particular promise for hybridization with trembling aspen are

The terrestrial subsidies to the stream affect stream-living biota in several ways, some of which are well-known while others less so.

The potential consequences of poor tree selection are gaps created along row removals, which are necessary for access to harvesting operations.

The consequences of using low stocking density as a management tool to increase individual tree growth rate of silver birch, and thereby shorten rotation length, were investigated. Low stocking density was found to result in greater diameter and basal area increment but may also result in trees with larger branches, a shorter length of clear bole, and possibly a reduced total height. The rapid growth had little effect on wood properties. Grain angle was unaffected, longitudinal shrinkage increased slightly, but conversely transverse and volumetric shrinkage declined. Density was not affected d

<p>This report describes an annual line detection algorithm for the WoodEye quality control system. The goal with the algorithm is to find the positions of annual lines on the four surfaces of a board. The purpose is to use this result to find the inner annual ring structure of the board. The work was done using image processing techniques to analyze images collected with WoodEye. The report gives the reader an insight in the requirements of quality control systems in the woodworking industry and the benefits of automated quality control versus manual inspection. The appearance and formation o

Pine tree substrate (PTS) produced from freshly harvested loblolly pine (Pinus taeda L.) trees has potential for replacing or reducing the use of aged pine bark (PB) and peat moss as container substrates for horticulture crop production. The objective of this work was to determine the factors influencing nutrient availability in PTS compared to PB or peat substrates. Chapter two reports data on the response of japanese holly and azalea to fertilizer rate when grown in PTS and PB. This study demonstrated that an additional 2.4 kgâ m-3 of Osmocote Plus (15N-3.9P-10K) controlled release ferti
