    Abstract: Methods of developing plant somatic embryos include incubating the plant somatic embryos at a first temperature for a first period of time followed by storing the plant somatic embryos at a second temperature for a second period of time. The first temperature can be in the range of about 23° C. to 30° C. and leads to rapid plant somatic embryo growth. The second temperature can be in the range of about 8° C. to 15° C. and slows plant somatic embryo development. Plant somatic embryos developed in this manner and implanted in artificial seeds show germination rates similar to zygotic embryos implanted in artificial seeds.

    Abstract: Wood-based composites, and methods for their manufacture, are provided. The composites include oriented wooden strands and cured bonding resin connecting adjacent strands. The composites are relatively low-density, having an average dry density of the wooden composites of about 15-28 pounds per cubic foot (pcf). The unique composition of the composites provide improved structural and insulating (thermal and acoustic) properties when compared to traditional engineered wood products (e.g., oriented strandboard).

    Abstract: A tree harvesting system includes a loader and a delimber. A camera system mounted on the delimber permits an operator to view an interaction area between a delimbing saw or toping saw and the tree being cut while the operator remains safely in a cab of the loader. The camera system provides image data to a display system located in the cab of the loader, and the image data may be viewed and/or processed to provide information about the interaction area, physical data about the tree, or some combination thereof. Advantageously, the tree harvesting system may allow for more accurate saw cuts at a preferred location of the tree, which in turn may result in a higher dollar amount and more efficient distribution of sticks to the mills.

    Abstract: Methods for interplanting a primary crop and an energy crop include preparing a plantation site for planting the energy crop. Plantation sites may include a primary crop planted in a first row and in a second row, the first row being separated by an intermediate area. The intermediate area is divided into a center portion and two side portions (a first side portion and a second side portion). Methods include lifting a soil and plantation debris mixture from the intermediate area, and redepositing a soil component of the soil and plantation debris mixture primarily in the intermediate area.

    Abstract: Methods of forming crosslinked cellulose include mixing a crosslinking agent with an aqueous mixture of cellulose fibers containing little to no excess water (e.g., solids content of 25-55%), drying the resulting mixture to 85-100% solids, then curing the dried mixture to crosslink the cellulose fibers. Systems include a mixing unit to form, from an aqueous mixture of unbonded cellulose fibers having a solids content of about 25-55% and a crosslinking agent, a substantially homogenous mixture of non-crosslinked, unbonded cellulose fibers and crosslinking agent; a drying unit to dry the substantially homogenous mixture to a consistency of 85-100%; and a curing unit and to cure the crosslinking agent to form dried and cured crosslinked cellulose fibers. Intrafiber crosslinked cellulose pulp fibers produced by such methods and/or systems have a chemical on pulp level of about 2-14% and an AFAQ capacity of at least 12.0 g/g.

    Abstract: The present disclosure provides formulations that provide fire resistance when applied as a coating to a surface (e.g., the surface of a wood product). The compositions include an isocyanate, a brominated compound that is reactive with the isocyanate to form a polyurethane, an intumescent component, and a fire-retardant synergist. Wood products treated with the composition, as well as methods for applying the composition to a surface, are also provided.
