| RESUMEN Alstroemeria L. es uno de los géneros de plantas chilenas más diversos y con un enorme potencial ornamental. Está representado por 35 especies, la mayoría distribuida entre los 28-38° S en la zona mediterránea de Chile central. Se reconocen 24 complejos, de los cuales 18 presentan problemas de conservación. Uno de estos complejos es Alstroemeria diluta E. Bayer. con dos subespecies: subsp. diluta y subsp. chrysantha Bayer. Alstroemeria diluta crece sólo en Chile; la subsp. diluta se distribuye desde los 34º15'S, en la Región de O'Higgins, hasta Cauquenes (36º00'S), en la Región del Maule y la subsp. chrysantha desde los 28º08'S, en la Región de Atacama, hasta Punta Curaumilla (33º05'S), en la Región de Valparaíso. Se realizó un studio comparativo... |

| Abstract Alstroemeria L. (Alstroemeriaceae) represents one of the most diverse genera of vascular plants in Chile. It contains approximately 54 taxa, 40 of which are endemic. The “complex” Alstroemeria magnifica is endemic to Chile, and it comprises four varieties: A. magnifica var. magenta, A. magnifica var. magnifica, A. magnifica var. sierrae, and A. magnifica var. tofoensis. It is distributed from Coquimbo to the Valparaíso Region. We analyzed karyotypes of 10 populations along its natural distribution. All the populations presented an asymmetric karyotype, with 2n = 16 chromosomes but with three different karyotypic formulae. Alstroemeria magnifica var. magnifica and A. magnifica var. sierrae presented the same karyotypic fomula, and A. magnifica var.... |

Cien. Inv. Agr. 41(2): 207-214. Critically endangered, Traubia modesta is endemic to Chile and belongs to the family Amaryllidaceae. In this research, a propagation protocol was developed for the in vitro cultivation of vegetative organs for this species. The twin scale explants were cultured in a Murashige and Skoog (MS) medium, supplemented with the growth regulators naphthaleneacetic acid (NAA) and 6-benzylaminopurine (BAP) in different concentrations. Plant preservative mixture (PPM) and polyvinyl pyrrolidone (PVP) were used as a biocide and an antioxidant,... |
