Bare Root Cuttings: Cuttings off a young radiata pine mother-plant, grown separately in the ground.

CellFor: CellFor Inc. Canada http://www.CellFor.com/home.html

Deployment Plan: Long-term plan of trialling and growing varieties of radiata pine tailored to individual customers’ needs.

Production Varieties: A group of trees with highly superior performance produced through production of genotypes selected in replicated field trials.

Cloning: The process of creating genetically identical copies of a single item.

Containerised Cuttings: Cuttings off a young radiata pine mother-plant, grown in individual small containers.

Control-Pollination: The process of pollinating a particular female with pollen from a particular male plant or tree.

Cuttings: Stem or shoot from plant, that grows to become second plant with same genetic makeup as original plant

DNA Fingerprinting: Scientific method aimed at identifying individuals (in this case, trees) based on their specific DNA base pair sequences.

Dothistroma Needle Blight: Pine tree disease, causing early shedding of needles, loss of foliage and health. The disease affects up to 20% of pine trees, but can be treated using fungicides.

Field Trials: The controlled and measured growing of a crop on land.

GEM: Genetic Evaluation Management system developed by ExSitez Ltd

Genetics: The scientific study of heredity, in particular how qualities or traits are transmitted from parents to offspring.

Germplasm: Germ cells and their precursors, serving as the bearers of heredity.

ha: Hectare

k: Thousand

kg: Kilogram

Loblolly Pine: Also called Pinus taeda. It is prevalent in the US, providing good fibre crops and valuable timber.

m: Million

m³: Metre cubed

Marker Aided Selection: Scientific method aimed at identifying genetic traits of individual (tree) as early as possible, using DNA sequences (markers).

Motherplant: The young radiata pine plants, grown in soil, to produce cuttings

pa: Per Annum

Propagation: Increasing/multiplying the numbers of plants through cuttings or seeds.

Radiata Pine: Also called Pinus radiata. It is prevalent in Chile, Spain, Australia and New Zealand, and is a versatile softwood tree usable for a range of end-products.

Seed: A compact structure from a flowering plant, containing an embryo with the capacity to develop into a new plant. Seeds have different genetic make up than either parent.

Seedlings: A plant grown from a seed.

Somatic Embryogenesis: Species-specific scientific process involving the production of many genetically identical plants from a single seed, with the initial step being splitting one embryo into two or more.

Tissue Culture: Growth of cells in the laboratory for scientific studies (also called in-vitro studies).
