Physiological and Technical Aspects of Cactus Pear [Opuntia ficus-indica(L.) Mill.] Double Rellowering and Out-of-Season Winter Fruit Cropping
2007
Abstract A commercial cactus pear plantation in Sicily, Italy was manipulated to induce late cropping. The spring flush of flowers and cladodes were removed as was the second induced bloom of flowers and cladodes. The third induced bloom was harvested for a late out-of-season crop of cactus pear (Opuntia ficus-indica Mill.). The double removal induced a third flush of flowers and cladodes during late August with a fruit production that ripened the following winter (to March). The number of flowers per fertile cladode was halved after the double removal and the length of the fruit development period increased from 100-120 days to 160-190 days for the out-of-season crop.

The effect of different amounts of cladode removal on reflowering of cactus pear (Opuntia ficus-indica(L.) Miller)
1994
SummaryThe removal of the spring flush of flowers and cladodes at bloom promotes reflowering in cactus pear. Studies were conducted to investigate the influence of different amounts of spring flush cladode removal (100%, 75%, 50%, 25%, 0%) on cactus pear reflowering. A positive linear correlation between the severity of spring flush cladode removal and the degree of reflowering was found. Primary (spring flush) and secondary (second flush) cladodes showed the same fertility in the year after formation. Two year old cladodes showed a significantly lower fertility and have only a marginal effect on plant yield.
Life Cycle Impact Assessment applied to cactus pear crop production for generating bioenergy and biofertiliser
2020
Among the potential uses of cactus pear, the generation of bioenergy (biogas) and biofertiliser (digestate), from the Anaerobic Digestion (AD) of cladodes and fruits, is surveyed in this paper. Data for Life Cycle Impact Assessment (LCIA) was drawn from a farm located in Roccapalumba (Palermo, Sicily, Italy), where three cultivars were cultivated: 1) yellow pulp cultivar; 2) red pulp cultivar; 3) white pulp cultivar. LCIA was applied to six scenarios: 1) current dry crop; 2) current irrigated crop; 3) dry crop for fruit and bioenergy production; 4) irrigated crop for fruit and bioenergy production; 5) dry crop for bioenergy production; 6) irrigated crop for bioenergy production. According t…
EVOLUTION OF ENDOGENOUS GIBERELLINS AT DIFFERENT STAGES OF FLOWERING IN RELATION TO RETURN BLOOM OF CACTUS PEAR (OPUNTIA FICUS-INDICA (L.) MILLER)
1998
Abstract The effect of flower emasculation, flower injection with paclobutrazol and the complete removal of the spring flush of flowers and cladodes on the changes in GA 3 concentration at different stages of bloom in flowers and fertile cladodes of Opuntia ficus-indica has been determined. Throughout the bloom period, the concentration of GA 3 was higher in intact flowers and the cladode than in flowers emasculated or injected with paclobutrazol. With the onset of blooming, GA 3 started to accumulate both in the flower and in the fertile cladode, and the highest concentration was measured at full bloom in the flower and in the cladodes whose flowers were not removed. Flower emasculation or…
El equipo lítico del asentamiento prehispánico de Atacames, Ecuador
2010
Se estudian los objetos líticos, domésticos y/o ceremoniales, de un yacimiento prehispánico ecuatoriano, Atacames. Comenzó a ser desarticulado por los españoles que se dirigían hacia la conquista del Perú (en el verano de 1527 los nativos fueron atacados). De aquella población han llegado a este tiempo numerosos vestigios, excavados y estudiados por los miembros de la Misión Arqueológica en Ecuador. (A)
Molecular analysis of the fungal microbiome associated with the olive fruit fly Bactrocera oleae
2015
Abstract A molecular approach was used to investigate the fungal microbiome associated with Bactrocera oleae a major key pest of Olea europea , using the ITS2 region of the ribosomal DNA (rDNA) as barcode gene. Amplicons were cloned and a representative number of sequenced fragments were used as barcode genes for the identification of fungi. The analysis of the detected sequence types (STs) enabled the identification of a total of 34 phylotypes which were associated with 10 fungal species, 3 species complexes and 8 genera. Three phylotypes remained unresolved within the order Saccharomycetales and the phylum Ascomycota because of the lack of closely related sequences in GenBank. Cladosporiu…
Una cabaña neolítica en los Picos de Europa
1996
La comunicación da cuenta de los trabajos realizados en la cabaña de la Calvera. Se describen los resultados de la excavación de una cabaña neolítica enmarcada en las investigaciones del conjunto megalítico de la Peña Oviedo (Camaleño, Cantabria). Se discuteu las diferentes estructuras, las industrias -microlíticas, macrolíticas y cerámica-, la función y la relación espacial y cronológica de la cabaña de la Calvera con las estructuras de la Peña Oviedo. In this paper the excavation of a neolithic house at La Calvera is reported The paper describes the results of the excavation of a neolithic house carried out within the Peña Oviedo (Camaleño, Cantabria) project. This report discusses the bu…
Poblado dirigido de Caño Roto J.L. Íñiguez de Onzoño, A. Vázquez de Castro Madrid 1956
2009
I Poblados dirigidos di Madrid, la cui stagione d'oro dura approssimativamente un anno, da luglio del 1956 allo stesso mese del 1957, vengono realizzati in aree periferiche rispetto al centro urbano, normalmente occupate da baracche o da abitazioni di fortuna, e prive di ogni tipo di pianificazione e urbanizzazione.

Phylogenetic relationship among genera of Polymorphidae (Acanthocephala), inferred from nuclear and mitochondrial gene sequences.
2013
Abstract Acanthocephalans of the family Polymorphidae Meyer, 1931 are obligate endoparasites with complex life cycles. These worms use vertebrates (marine mammals, fish-eating birds and waterfowl) as definitive hosts and invertebrates (amphipods, decapods and euphausiids) as intermediate hosts to complete their life cycle. Polymorphidae has a wordwide distribution, containing 12 genera, with approximately 127 species. The family is diagnosed by having a spinose trunk, bulbose proboscis, double-walled proboscis receptacle, and usually four to eight tubular cement glands. To conduct a phylogenetic analysis, in the current study sequences of the small (18S) and large-subunit (28S) ribosomal RN…
