Wood sampling

Whole tree sample based on

discs at 10, 30, 50, 70, and 90% of ht to 5cm DOB

Wood tested for:

Basic density Pulp Yield Alkali consumption Fibre length

Cores also taken at BH
NIR analysis (with ENSIS)

Clone trials

STP, 5TP, and 72TP designs

depending on plants available

60 clones in trials of at least 8

plants

Range of sites tested within

APFL planting limit of 120km of Albany

Improved seedling controls in

all trials

Joint trials with other

companies

Developing a breeding population

All clones are being

planted in a Breeding Arboretum and being

ut-crossed
Progeny trials will be

planted with this seed

Combination crosses

are also being made of good growing and good rooting clones

Germ-plasm exchange

with other companies
