NUNEZ-COLIN, Carlos Alberto. Distribution and eco-climatic characterization of southern false serviceberry (Amelachier denticulata (Kunth) Koch) in Mexico. Rev. Chapingo Ser.Hortic [online]. 2010, vol.16, n.3, pp.195-206. ISSN 2007-4034.

The Southern false serviceberry (Amelanchierdenticulata (Kunth) Koch) is a fruit-bearing shrub native to Mexico, and there are not enough studies about the use, distribution, and diversity. This research aimed to make a distribution model and eco-climatic characterization as well as current and future models of suitable areas for cultivation of A. denticulata using Geographical Information Systems (GIS). The southern false serviceberry was distributed mainly in central Mexico. Three eco-climatic groups were found; group 1 showed climate C, group 2 climate A(C), and group 3 climate Bs. The most suitable regions of cultivation were Guanajuato, Queretaro, and Hidalgo. This research will serve as basis of planning the best conservation strategy of A. denticulata genetic resources and to design the correct way of collection. The three different climatic groups should have diverse germplasm, which is important collect from each group. The best regions to establish in vivo germplasm bank are northeast Guanajuato, central and southern Queretaro, and southern Hidalgo.
