Genetic Considerations in Propagating Diverse Tree Species

Nursery managers are growing a wider diversity of plant species for ecological purposes. These activities may affect the adaptation, diversity, and performance of lots. Managers can exercise control by selecting and working with lots at different genetic levels: species, seed zone, seed stand, parent phenotype, and even individual tree genotype. Judicious mixing of genetic sources is a powerful tool to enhance the genetic diversity and evolutionary potential of plantations. Selection for specific juvenile traits in the uniform nursery environment can be very effective. The genetics of non-commercial tree species can be developed to a working level quickly using biochemical markers, common gardens, and knowledge from the major conifers. In general, the other species have more complex genetic structures and are more specialized in their site and cultural requirements.
