HERNANDEZ-MARTINEZ, Miguel Ángel et al. Morphological variability by means of seed traits of populations of Amelanchier denticulata (Kunth) Koch, from Guanajuato, Mexico. Rev. Chapingo Ser.Hortic [online]. 2011, vol.17, n.3, pp.161-172. ISSN 2007-4034.

The Mexican serviceberry (Amelanchierdenticulata (Kunth) Koch.) is a fruit-bearing shrub belonging with to the family Rosaceae subtribe Pyrinae, which is native to Mexico. There are no studies to know its diversity and its reproductive system. Furthermore, for having an insight of the morphological variability, six populations of A. denticulata from Guanajuato, Mexico, were characterized by means seed traits. All the populations showed high intra and inter-population variability. The analyzed seed traits were discriminating to distinguish the different populations mainly by traits related to the seed size, followed by the seed shape traits. The apomixis degree is not clear on this species due to the high intra-population variability. However, more detailed studies are needed to conclude whether or not apomixis is present in A. denticulata.
