Lipid peroxidation and seed emergency in progenies of the yellow passion fruit plant

The objective was to evaluate the percentage of emergency plantlets and lipid peroxidation in seeds of 29 half-sib progenies of yellow passion fruit (Passiflora edulis Sims.) after 24 months under storage. The experimental design was completely randomized, with four replications of 50 seeds each, from which the treatments were the progenies (1-29). The evaluation of the percent plantlet emergency was accomplished at 14 and 28 days after sowing. The lipid peroxidation of the seeds was expressed as malondialdehyde (MDA) content that was determined by the TBARS method. Approximately 21% of those half-sib progenies maintained the viability of their seeds for twenty-four months under storage. The results point out a remarkable genetic variability for vigor and emergency of the yellow passion fruit plantlets, with occurrence of individuals with high and other ones with low capacity to maintaining the physiologic quality of their seeds after storage.

Effect of GA3, KNO3, and removing of basal point of seeds on germination of sweet granadilla (Passiflora ligularis Juss) and yellow passion fruit (Passiflora edulis f. flavicarpa)

Passiflora seeds germinate erratically presenting difficulties for their handling in a greenhouse. The effect of removing of basal point of seeds (RB) and pre-imbibition of seeds of sweet granadilla and yellow passion fruit in 50, 100, 200, and 400 mg mL-1 solutions of gibberellic acid (GA3) or 0.1% KNO3 solution was studied. The experiment was conducted in greenhouses in La Plata, Colombia. Two accessions PrJ1 and PrJ2 of sweet granadilla were evaluated. There were calculated the final percentage of germination (PG), mean germination time (MGT), and the mean germination rate (MGR). The leaf area and dry mass of seedlings were measured 22 days after sowing (das); with this data, specific leaf area and relation root/shoot were calculated. In all cases, the highest germination percentages were achieved treating seeds with KNO3 (89, 92, and 87% for yellow passion fruit, PrJ2, and PrJ1, respectively), but the increase in MGR (3.3 germinated seeds per day) and the decrease in MGT (16 days) were only significant for PrJ1. RB had a significant reduction of PG in all cases (28, 12, and 33% for passion fruit, PrJ2 and PrJ1, respectively). With the increase in the concentration of GA3, PG was reduced for two accessions of sweet granadilla, for yellow passion fruit this trend was not clear, no treatment with GA3 showed significant differences with the control. Leaf area (24.07 cm2) and dry mass of seedlings (135 mg) were significantly higher than seeds previously treated with KNO3 only for PrJ1.The solution of KNO3 0,1% is recommended to improve the germination and initial growth of granadilla seedlings.

In vitro pollen germination and pollen viability in passion fruit (Passiflora spp.)

The use of Passiflora species for ornamental purposes has been recently developed, but little is known about pollen viability and the potential for crossing different species. The objective of this study was to evaluate the pollen viability of six Passiflora species collected from different physiological stages of development through in vitro germination and histochemical analysis using dyes. The pollen was collected in three stages (pre-anthesis, anthesis and post-anthesis). Three compositions of culture medium were used to evaluate the in vitro germination, and two dyes (2,3,5-triphenyltetrazolium chloride, or TTC, and Lugol's solution) were used for the histochemical analysis. The culture medium containing 0.03% Ca(NO3) 4H2O, 0.02% of Mg(SO4 ).7H2O, 0.01% of KNO3, 0,01% of H3BO3, 15% sucrose, and 0.8% agar, pH 7.0, showed a higher percentage of pollen grains germinated. Anthesis is the best time to collect pollen because it promotes high viability and germination. The Lugol's solution and TTC dye overestimated the viability of pollen, as all accessions showed high viability indices when compared with the results obtained in vitro.

Los beneficios de la Terapia con animales y naturaleza sobre las personas con diversidad funcional

El objetivo del proceso de investigación de mi Trabajo de Fin de Grado recae en los beneficios que tienen la naturaleza y los animales sobre las personas con diversidad funcional y más precisamente sobre las personas con trastorno mental. Lo que me motivó en esta investigación fue en primer lugar mi pasión por estos ámbitos y en segundo lugar porque conocía la existencia de dos proyectos magníficos. Uno en el Zoo de Barcelona (Proyecto de voluntariado de personas con Trastorno Mental grave con el Zoo de Barcelona) y otro en la protectora de perros y gatos (CCAAS : Centro Comarcal de Atención a animales de compañía). Para eso me he sumergido en estos proyectos para poder comprender el impacto que tenía la naturaleza y los animales sobre los usuarios. Han participado directamente cinco usuarios. He usado varias metodologías como la observación, el diario de campo, la fotografía y la entrevista semi-estructurada. Los resultados extraídos de la investigación muestran como existen beneficios y tienen un impacto positivo hacia las dimensiones bio-psico-social de las personas con trastorno mental. Las limitaciones del proyecto dependen de la voluntad de participación de cada usuario y a la naturaleza del estudio.

Passion for Ski Mountaineering and Relationship Quality: The Mediating Role of Team Cohesion

Vallerand and colleagues (2003) developed a dualistic model of passion, wherein two types of passion are proposed: harmonious and obsessive passions that predict adaptive and less adaptive interpersonal outcomes, respectively. The present study examined the mediating role of team cohesion between passion and relationship satisfaction and interpersonal conflict with teammates. We hypothesized that harmonious and obsessive passions would be positively and negatively related to team cohesion, respectively, which, in turn should be associated with high relationship satisfaction and low interpersonal conflict with teammates. Ski mountaineers (N = 559) participating in the "Patrouille des Glaciers" completed an initial questionnaire assessing harmonious and obsessive passions for ski mountaineering and team cohesion before the race. After the race, a second questionnaire was completed and assessed participants' relationship quality with teammates and team conflict during the race. Results from path analyses supported the hypothesized model. Future research directions are discussed in light of the dualistic model of passion and team cohesion literature.

Dial M for Murder: A Case of Passion Killing, Criminal Evidence and Sultanic Power in Medieval India

This paper considers the structures and applications of the criminal judicial system in the Islamic Later Middle Period as it developed in India under the sultans of Delhi (1200-1400 CE). A fundamental issue in crime and punishment is the relationship between sultanic power and religious authority. Particularly at stake in this relationship is the question of who can sanction the highest form of punishment, i.e. the death penalty (siyāsa). Contemporary historians and scholars in the study of religion investigating the relationship between sharīʿa and siyāsa to reveal the extent and limits of sultanic power show a system of governance that allowed for the delegation of authority, particularly in the area of the judiciary, from the sultan down to viziers and judges. Some scholars depict the relationship between the ʿulamāʾ and the sultan as a kind of stand off. The actual dynamics of legal jurisdiction were much more complex. This study proposes a new interpretive framework for understanding the relationship between political power and religious authority through a critical analysis of the criminal judicial system, law, and historical narrative. In particular, I consider a murder case described by Shams al-dīn Sirāj ʿAfīf in one of the most significant histories written in the later Delhi Sultanate, the Tārīkh-i Fīrūzshāhī.

Greek by Steven Berkoff (1980): The Risky Transformation of Sophocles’ Oedipus Rex into a Love Story

[eng] Can Sophocles’ Oedipus Rex really be transformed into a love story, as in Steven Berkoff’s drama entitled Greek? This article will show that, although Greek may be viewed by some critics as simply a provocative drama by no means intended to justify incest, directors, actors and critics in the end become enthralled by the powerful love story that ensues between Eddy and his wife and mother. This perspective reveals that Berkoff’s adaptation, intended to portray the social degradation of 1980s Great Britain, is in reality a quite risky proposition since it represents a flat denial of the tragic awareness of contemporary men and women. However, if this is the case, the audience, apart from enjoying the performance of Berkoff’s drama, might question, even from a non-fundamentalist perspective within the classical tradition, to what degree it makes sense to take inspiration from a text by Sophocles that precisely illustrates the great tragic awareness of the ancient Greeks.

Greek de Steven Berkoff (1980): L’arriscada conversió de l’Èdip rei de Sòfocles en una love story

[cat] ¿Podem convertir l’Èdip rei de Sòfocles en una història d’amor com ho fa Berkoff a Greek?. Tot i que alguns crítics llegeixen Greek només com un drama provocador que de cap manera intenta justificar l’incest, directors, actors i crítics resten finalment captivats per la impactant història d’amor entre Eddy i la seva esposa-mare. Això demostraria que l’adaptació de Berkoff, pensada per a il·lustrar la degradació social de la Gran Bretanya dels 80s, esdevé una proposta arriscada, car significa negar de fet la consciència tràgica dels homes i dones contemporanis. Tanmateix, si aquest és el cas, lectors i espectadors, a banda de l’indubtable plaer d’assistir a la representació de Greek, poden preguntar-se, fins i tot des d’una perspectiva no fonamentalista de la tradició clàssica, si té sentit inspirar-se en el text de Sòfocles, el qual mostra precisament la gran consciència tràgica dels grecs.

The love marriage : challenging Victorian myths in Anne Brontë’s 'The Tenant of Wildfell Hall'

La tesina analitza com Anne Brontë desafia el mite del casament romàntic a la novel·la The Tenant of Wildfell Hall. Argumento que aquesta crítica es fa mostrant les conseqüències nefastes d’un matrimoni (entre l’Arthur i l’Helen) basat en l’atracció i en la idea que una dona pot salvar un home de mala vida. Malgrat que la novel·la acaba amb un altre casament (entre l’Helen i en Gilbert), si s’analitza en detall es pot veure que presenta elements subversius. Per exemple, la seva unió està basada en igualtat intel·lectual i compatibilitat de caràcters, enlloc d’igualtat econòmica i social
