Abrégé
A process for producing pellets or granules comprising fibres of a lignocellulousic material, for use as a feedstock in plastics manufacture, conveying in a dry or wet air stream and applying to the fibres a liquid formulation comprising one or more polymers, monomers, or oligomers, forming the fibres into a solid product, and breaking down the solid product to produce said pellets or granules. Typically the conduit conveys the fibres in a plant for manufacture of fibre board.

Abrégé
A process for producing a composite product comprising fibers of a lignocellulosic material or natural fibers and a plastics material utilizes a liquid or particulate binder formulation comprising a thermoset resin and a thermoplastic polymer, monomer, or oligomer. A composite product is formed for use as or in forming a feedstock in plastics manufacture may be broken down under heat and mechanical shearing in a plastics extrusion machine to release the major fraction of the fibers, or the product may be useful as an intermediate product in other form or as an end product.

Abrégé
The invention provides a method for identifying a tree with a genotype indicative of increased diameter growth, the method including detecting in the tree, or a sample derived from the tree, by direct or indirect methods, the presence of an allele of the dehydrin gene that includes an additional serine (S) residue in the casein kinase II (CKII)-hydrophilic charged domain of the dehydrin gene, relative to more commonly identified alleles, such as those disclosed herein. The invention also provides the isolated polynucleotides of such alleles, constructs, host cells, plant cells and plants comprising such polynucleotides. The invention also provided methods for producing plants with increased diameter growth, using the polynucleotides of the invention, and plants produced by the methods.

Abrégé
A process for producing a thermoformable fibre-plastics composite product comprising lignolcellulosic or natural fibres, particularly but not exclusively useful as an intermediate product in subsequent manufacture, comprises conveying the fibres in a dry or wet air stream and applying to the fibres a thermoplastic binding agent, and forming the fibres into a solid or semi-solid product such as a panel, which is thermoformable. In at least a preferred embodiment the process may be carried out in known plant for manufacture of medium density fibre board.
