| Los síntomas de amarilleamiento y clorosis presentan alta incidencia en el Banco de Germoplasma de la Caña de Azúcar de Cuba. El objetivo de este trabajo fue determinar su asociación con fitoplasmas, Xanthomonas albilineans (Ashby) Dowson, los virus del mosaico y de la hoja amarilla. Para ello se seleccionaron del Banco de Germoplasma aquellos genotipos que manifestaron síntomas de amarilleamiento y clorosis de forma sostenida durante el ciclo de vida del cultivo. Se diagnosticaron ambos virus empleando la técnica Reverso Transcriptasa-Reacción en Cadena de la Polimerasa (RT-PCR), mientras que X. albilineans y fitoplasmas fueron estudiados por PCR anidada. Del total de muestras, ocho resultaron positivas al virus de la hoja amarilla, tres al mosaico, ocho... |

Luma chequen, a small tree or large shrub belonging to the Myrtaceae family, is endemic to South America and has medicinal, nutritional and ornamental potential. However, its native habitat is deteriorating gradually, and it is suffering from the effects of fragmentation that is being caused by the conversion of forest land to agricultural land and the natural expansion of monocultural plantations of exotic species, such as Pinus radiata. The purpose of this work is to develop an effective procedure for establishing in vitro cultures of the native Chilean species L. chequen. Aseptic nodal... |

| BACKGROUND: For the first time, a morphometric characterization of chaura (Gaultheria pumila) fruits has been conducted between natural populations growing in the Villarrica National Park, Araucania Region, Chile. Chaura is a native Ericaceae from Chile that produces aromatic and tasty fruits which could be of agricultural interest. RESULTS: To influence the decision for a further domestication of G. pumila, both the fruit sizes (indicator of productivity) and the nutritional properties of the fruits have been determined from different subpopulations. Samples were a total of 74 plants and 15 fruits per plant which were randomly harvested following its natural distribution around the Villarrica volcano. Altogether, fresh weight, shape, color, diameter in... |
