The steps in the Production Cycle are:
-
Establishment of field trials on forest growers’ land to compare performance of different varieties of radiata pine. Field trials take 4-6 years before providing useful data for ranking.
-
Placement of tissue samples from varieties under test in long-term storage using cryo-preservation (liquid nitrogen), to maintain juvenility.
-
Extraction of tissue of the few best selected Production Varieties from long-term storage.
-
Growth of these Production Varieties into motherplants in the laboratory, using somatic embryogenesis, tissue culture and greenhouse technology.
-
Planting of selected motherplants of Production Varieties in field/nursery conditions for the subsequent production of cuttings.
-
Setting of cuttings from motherplants in the nursery, either as bare root or individually containerised, as specified by the customer
-
Planting of cuttings, the end-products, on forest land.
