| Popis: |
This chapter gathers three species locally known for their multipurpose use whose natural forests were overexploited and intensively logged, both for the use of the wood and due to the advance of the agricultural frontier. Their natural ranges and disjunct distribution areas are described, as well as their economic relevance. The adjustment of molecular protocols for these non-model species is not trivial, and results are presented together with the initial studies for the genetic characterization of their natural populations through molecular markers. Domestication experiences including seed physiology, nursery, silviculture, breeding, and propagation techniques showed different advances in each species. Incipient breeding strategies for Cordia trichotoma and Handroanthus impetiginosus developed particular sampling procedures and massal selection in the natural stands. Vegetative propagation of the selected individuals is being performed for the establishment of clonal seed orchards. The potential of Anadenanthera colubrina var. cebil to be included in domestication programs in Argentina is discussed. Finally, the future steps in breeding and conservation programs are delineated. |
