Experiment Design in Provenance and Progeny Trials
An interesting and frustrating aspect of the development of tree improvement in NZ concerns the design of the trials for provenance and progeny testing. The number of sites, experiment design, replication number and trees per plot are critical in forest experiments. This chapter deals mainly with the problems of the earlier provenance trials with their very large plots of up to 300 seedlings and with 1 to 3 replications of each provenance per site. All trials are listed in the Appendix with plot size, number of replications per site and number of sites for each species.
