This study evaluated the expression of defense compounds by the secondary metabolism of Eucalyptus globulus plants subjected to attacks by the insect Ctenarytaina eucalypti (blue gum psyllid) and abiotic mechanical damage using gas chromatography with flame ionization detection (GC-FID) and mass detection (MS). The results show that both biological and mechanical attacks activated defense responses in the plants. We identified 34 compounds in the leaves of the treated plants. In the case of the plants damaged by C. eucalypti, four of the compounds differed from those of the control: three oxygenated monoterpenes (borneol, exo-2-hydroxy cineole and thymol) and one quinone (6-acethyl-flaviolin). In the case of the mechanical damage, five compounds differed from the control: three sesquiterpenes (alloaromadendrene, eremophilene, and caryophyllene-oxide), borneol, and 6-acethyl-flaviolin. According to the results, different compounds are biosynthesized when faced with biotic and abiotic inductions, indicating a certain level of specificity in the response of the plants to different types of damage.

This study evaluated the expression of defense compounds from the secondary metabolism of Eucalyptus globulus plants, subjected to direct and indirect stimuli by the insect Ctenarytaina eucalypti (blue gum Psyllid). Results showed that defense responses were activated in plants in all tested cases. Were detected and identified thirty-two compounds in the leaves of treated plants, of which five compounds differed with the control, and all are part of the chemical defenses from the plants, three of them were oxygenated monoterpenes (borneol, exo-2-hydroxy cineole and thymol), a aromatic carboxylic acid (benzoic acid) and a quinone (6-acethyl-flaviolin). The plants induced by volatile compounds and by indirect entomological manner, showed its capability to synthesize defensive compounds without a wound that promotes these responses. Were also found some constitutive secondary metabolites over expressed in the different inductions compared with the control.

The expression of defensive compounds derived from secondary metabolism in plants of Eucalyptus globulus Labill, and the persistence of these in vegetative propagation was evaluated by gas chromatography with flame ionization (GC-FID) and mass spectrometry (MS). The plants were induced by attack from the insect Ctenarytaina eucalypti ("blue gum psyllid") and by mechanical damage. Defense responses were activated in plants for the different types of tested induction. We identified four defensive compounds present in the leaves of plants induced in entomological form (β-terpineol, aromadendrene, caryophylleneoxide and eremophilene); all remained in the vegetative propagation. After mechanical induction, we identified three compounds (β-terpineol, aromadendrene and ledol), of which ledol and aromadendrene persisted in the vegetative propagation. Virtually all the compounds detected, in addition to persisting in the vegetative propagation, showed specificity for the induction type, whether entomological or mechanical, except for aromadendrene, which was expressed in both types of induction.

RESUMENEn este artículo se desarrolla inicialmente una propuesta teórica sobre la noción del "detalle" y su funcionamiento en el relato de fines del siglo XIX y comienzos del XX para proponer, enseguida su análisis en el cuento "La Ninfa" de Darío. Partiendo de algunas tesis sobre el poder disciplinario que muestran como "hace presa" en el cuerpo, descomponiéndolo, analizándolo, y rearmándolo en una verdadera "anatomía política del detalle" (Foucault), avanzamos mucho más allá para proponer que la erótica y la estética también anidan en el pormenor. Así sucede en el cuento "La ninfa" de Rubén Darío donde intentamos demostrar que la parodia del detallismo realista culmina en que la estética y la erótica del modernismo pueden ser consideradas una estética y erótica del detalle.Palabras clave: Rubén Darío, ninfa, detalle, óptico, háptico, parodia.1 Este trabajo corresponde al Proyecto N° 1121091 del Fondo Nacional de Desarrollo Científico y Tecnológico (FONDECYT), titulado: "De la "aceptación" a la resistencia: una anatomía del detalle disciplinario en la narrativa de los siglos XIX y XX." 154 ABSTRACTThis article starts by developing a theoretical proposal on the notion of "detail" and how it functions in the short story of the 19th and early 20th centuries, and then goes on to propose an analysis of this notion in Darío's short story "La Ninfa" (The Nymph). Starting with certain theses on disciplinary power which show how it "takes over" the body, breaking it down, analysing it and reassembling it into nothing less than a "political anatomy of detail", we go much further and propose that the erotic and the aesthetic also lurk in the detail. This occurs in Rubén Darío's short story "La Ninfa", where we try to show that parody of realist obsession with detail leads to the conclusion that the modernist aesthetic and erotic may be considered an aesthetic and an erotic of detail.
