16.3.2 Domestication Experience and Breeding Strategy
According to nursery trials, H. impetiginosus seeds germinate 7–10 days after sowing, with a germination capacity of 90%. In addition to this excellent germination
performance, the species had a great initial growth compared to other Handroanthus
species, reaching the field transplant size at 150 days, with a height of 37–40 cm
(Zapater et al. 2005).
Several experimental plots of the species have been installed in NWA; however
many are not documented. A 6-year-old plantation installed in Yuto Experimental
