“…Our results suggest that the color of the flowers can be used as a new taxonomic character in Alstroemeria and that var. maxima probably belongs to A. pulchra as originally proposed and not to A. magnifica [29]. Colorimetric studies were carried out also in A. presliana [30].…”

“…In Alstroemeria, the color of the flower has often been used in keys and descriptions [11,14,15,22,23], however, most of the time, the described color corresponds to a subjective perception of the same by the human eye. The color of the flowers is taxonomically significant in Alstroemeria [14,29,30]; the however, some species showed variability in the background color [30], because it depends on several ecological factors such as temperature and pH [31]. In order to describe objectively the color (mainly the background color) of the different tepals (external, upper internal and lower internal), the CIElab system [32] has been used in some species complexes of Chilean Alstroemeria [29,30] ( Figure 3).…”

The genus Alstroemeria encompasses approximately 80 species endemic to South America, with 2 centers of diversity (Chile and Brazil). In Chile, Alstroemeria represents one of the most diverse genera of vascular monocotyledons, comprising more than 50 recognized or accepted taxa (36 species, 11 subspecies and 10 varieties) from which ca. 82% are endemic to the Mediterranean zone of central Chile, one of the world's diversity hotspots. The taxonomy of the genus is very difficult due to the great variability of the vegetative and floral traits. Moreover, a number of taxa have been recently described and several nomenclatural changes have been proposed. In order to elucidate the taxonomy of some Chilean complexes of Alstroemeria, an integrative approach including morphology, colorimetry, cytogenetic, multivariate statistical analyses of morphological variation and DNA-molecular studies have been conducted. In this chapter, we review the literature concerning these approaches; a checklist of the species growing in Chile is provided including all published names, references to the original protologues, accepted names, synonyms and the biogeographic status (endemic or native) of the accepted taxa; maps illustrating the diversity of the genus in South America and its distribution in Chile were constructed.

Comparative karyotypic analysis and cytotaxonomy in the Alstroemeria ligtu L. (Alstroemeriaceae) complex of Chile

et al. 2015

Artículo de publicación ISISin acceso a texto completoDue to the variability in morphology and color of the flowers as well as the excellent post-harvest durability of Alstroemeria, many species are cultivated as ornamental and cut flowers. Alstroemeria ligtu L., endemic to Chile, has also been a source of artificial hybridizations for development of new cultivars. Cytogenetic studies provide clues for possible breeding programs and taxonomically useful data to clear up infraspecific relationships of Chilean native populations. Three subspecies are recognized within A. ligtu: subsp. ligtu, subsp. splendens Munoz-Schick, and subsp. simsii (Sprengel) Bayer. The objective of this paper is to characterize karyotypically these subspecies and to clarify their taxonomic status. Fourteen populations were collected throughout its distributional range. Chromosome number, karyotypic formulae, karyotypes, ideograms, intrachromosomal asymmetry index M-CA, and interchromosomal asymmetry index CVCL were calculated. All studied populations showed 2n = 2x = 16 chromosomes. Subspecies ligtu and simsii are clearly differentiated from each other in M-CA and together from subsp. splendens with CVCL. Intrachromosomal asymmetry index revealed two populational groups within subsp. splendens. These populations also differ in karyotypes formulae, habitat, soil type, and distribution. We concluded that a fourth subspecies should be described from populations located in the lower part of the cordillera de los Andes in the Region of Maule. Populations of higher elevations correspond to those already described as subsp. splendens.Fondecyt 113034
