Inner Areas between theories and practices. An ongoing laboratory

2022

The contribution proposes a reflection on the laboratories that are being formed in inner areas, and in which universities and researchers play a central role both from a technical point of view and in the advancement of theoretical reflection. The article is structured in four parts: it starts with a framework on inner areas as a place of fragility and opportunity, it moves on to the laboratory dimension that is triggered in the relationship with institutions, such as the university. It concludes with a reflection on the rooting dimension that the laboratory engenders in a territory.

Auxin application and cutting length affect rooting in Cuphea hyssopifolia stem cuttings

2017

The effect of cutting length and indole-3-buyric acid (IBA) application on adventitious root formation stem cuttings was studied in Cuphea hyssopifolia. Softwood terminal cuttings of a clone grown in Sicily were trimmed to three lengths (2, 4 or 6 cm) and inserted to a 1-cm depth in bottom heated plastic trays containing a humidified peat-vermiculite mixture 1:2 (v/v). To verify the cutting response to different auxin concentrations, cuttings were dipped to a 1.0 cm depth in a 500ppm or 1000 ppm IBA solutions for 10 seconds. Cutting percent survival was 100%. Regardless of cutting length, the highest rooting percentage was obtained with IBA at 1000 ppm (avg. 86.7%), whereas rooting signific…

Citrus biotechnology

2020

Agricultural crops that can better withstand the changing climatic and pathogen landscape have been produced through natural selection throughout the millennia and, in recent years, through the process of human-assisted plant breeding and selection. However, a lack of genetic diversity in many commercially cultivated crops (due to monoculture) has made them more vulnerable to biotic and abiotic stresses (Esquinas-Alcazar, 2005; Keneni et al., 2012). Citrus, belonging to the Rutaceae family, is one of the most important commercial woody fruit crops in the tropical and subtropical areas of the world. The origin of citrus is traced back to parts of tropical and subtropical Southeast Asia (Wu e…

Narrativa dei Caraibi nel nuovo millennio

2020

L’etichetta “Letterature franco-caraibica” utilizzata, per convenzione, dalla critica per indicare unitariamente la produzione letteraria in lingua francese della regione centrale del Continente americano è assai impropria. La regione dei Caraibi abbraccia, infatti, sia alcune delle isole dell’arcipelago delle Piccole Antille (Martinica, Guadalupa), sia l’isola di Haïti, che fa parte delle Grandi Antille, che la Guiana incastonata sulla costa orientale dell’America meridionale. Pur nella diversità dei movimenti ideologici e degli avvenimenti storici che si sono succeduti nella regione, le opere letterarie degli scrittori caraibici francofoni, nel loro insieme, hanno oscillato, e continuano …

The definition "Franco-Caribbean Literature" used by convention from the critique to indicate all the literary production in French of the central region of the American continent is very improper. The Caribbean region includes in fact the islands of Martinique Guadeloupe Haïti and the Guiana. Despite the diversity of ideological movements and historical events that took place in these countries the literary works of the Caribbean writers have fluctuated and continue to oscillate between two tendencies: that of rooting in tradition and that of escape from it. The writers show themselves open to comparison and dialogue with other literary and cultural traditions in order to create a narrative form that corresponds to the many inheritances of those composite populations. Here the cultural syncretism that has been created allows to recognize a common identity in the name of all that the West wanted to extinguish. The common denominator seems to be inverted in the contradictory result of courageous but dangerous encounters of curiosities that can lead to conflicts to exclusions.

Effect of rhizosphère bacteria and endomycorrhizal fungi on the growth of Christmas rose (Helleborus niger L.)

2010

International audience; Micropropagated and vegetative (by rhizome cuttings) propagated plants of Christmas rose ( Helleborus niger L.) were tested for their responses to the inoculation with microorganisms in order to optimize root growth and development. In our experiment, plants were inoculated with arbuscular endomycorrhizal fungi or/and Agrobacterium radiobacter . The investigation indicated that inoculation with A. radiobacter had significantly positive effect on growth and development of plants multiplicated by in vitro techniques as compared to the dual inoculation. This study indicates that, biotization can be beneficial to plant growth in in vitro plant production systems but inoc…

Micropropagation of Genista aetnensis [(Raf. ex Biv.)DC]

2015

Genista aetnensis [(Raf. ex Biv.)DC] is a large deciduous shrub or small tree native to the Italian islands of Sardinia and Sicily. Being winter hardy and characterized by high plasticity in altitude and ecology, the species is grown in gardens and landscaping, both for flower and for its attractive shape. Genista species are generally propagate by seed or semi hardwood cuttings. In this report an efficient in vitro technique for propagation of G. aetnensis was investigated. Multiple shoots were induced on nodal segments of a mature plant of Genista aetnensis . The Murashige and Skoog medium, augmented with different concentrations of benzyladenine either singly or in combination with indol…

Micropropagation of Metrosideros excelsa

2008

Multiple shoots were induced on stem segments of a 8-year-old plant of Metrosideros excelsa Sol ex Gaertn. ‘Parnel’. Axillary shoots produced on uncontaminated explants were excised, segmented and recultured in the same medium to increase the stock of shoot cultures. The Murashige and Skoog (MS) medium, augmented with different concentrations of 2- isopenthenyladenine (2iP) and indole-3-acetic acid (IAA), either singly or in combinations, as potential medium for shoot multiplication by nodal segments was tested. In the following experiment equal molar concentrations of four cytokinins [2iP, kinetin, zeatin and N6-benzyladenine (BA)] in combination with equal molar concentrations of three au…

Improved micropropagation in Polygala myrtifolia

2004

Stem segments from apical shoot tips of Polygala myrtifolia were used as primary explants to establish in vitro cultures. Axillary shoots produced on noncontaminated explants were excised and recultured in the same medium to increase the stock of shoot cultures. Equal molar concentrations of five cytokinins 2-isopentenyladenine (2iP), kinetin, zeatin, N6-benzyladenine (BA) and adenine were tested for ability to induce axillary shoot development from double node stem segments. The highest rate of axillary shoot proliferation was induced on Murashige and Skoog agar medium supplemented with 1.8 M BA. Seven indole-3-acetic acid (IAA) concentrations (2.8, 5.7, 8.6, 11.4, 14.3, 17.1 M) were t…
