Main viruses in sweet cherry plantations of Central-Western Spain

Sweet cherry trees (Prunus avium L.) are susceptible to a range of diseases, but there have been no studies to date about the viral infection of sweet cherry trees in Spain. To determine the phytosanitary status of Spanish sweet cherry plantations, the incidence and leaf symptoms induced by Prune dwarf (PDV), Prunus necrotic ringspot (PNRSV) and Apple chlorotic leaf spot (ACLSV) viruses were investigated during 2009. Young leaf samples were taken from 350 sweet cherry trees, corresponding to 17 cultivars, and were analysed by double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA). To associate the leaf symptoms with the virus, 50 mature leaves from each infected tree were visually inspected during the summer. The ELISA results revealed that 72 % of sweet cherry trees were infected by at least one of the viruses. PDV occurred in all sampled cultivars and presented the highest infection rate, followed by ACLSV and PNRSV. A high number of trees showed asymptomatic, in both single and mixed infections. The leaf symptoms associated with the viruses involved generalized chlorosis around the midvein (PDV), chlorotic and dark brown necrotic ringspots on both secondary veins and intervein regions (PNRSV), chlorotic and reddish necrotic ringspots (ACLSV) and generalized interveinal chlorosis (PDV-PNRSV)

Sour and duke cherry viruses in South-West Europe

This study investigated the phytosanitary status of sour and duke cherry genetic resources in the Iberian Peninsula, and the incidence and leaf symptoms induced by the Prunus necrotic ringspot virus (PNRSV), Prune dwarf virus (PDV) and Apple chlorotic leaf spot virus (ACLSV). Young leaf samples were taken from 204 sour and duke cherry trees belonging to ten cultivars, and were assayed by DAS-ELISA. Samples positive for any of the three viruses were also tested by RT-PCR. To associate the leaf symptoms with virus presence, 50 mature leaves from each infected tree were visually inspected during the summer. The ELISA and RT-PCR results indicated that 63% of the cherry trees were infected by at least one of these viruses. PNRSV occurred in all cultivars sampled and presented the highest infection rate (46%), followed by PDV (31%) and ACLSV (6%). Many trees, (60 to 100%), were asymptomatic while harbouring single and mixed virus infections. The leaf symptoms associated with the viruses included chlorotic and dark brown necrotic ringspots on secondary veins and interveinal regions, for PNRSV, generalized chlorosis around the midveins, for PDV, chlorotic and reddish necrotic ringspots, for ACLSV, and generalized interveinal chlorosis, for mixed PNRSV and PDVinfections

Orientación profesional e igualdad de género en enseñanza no reglada

El objetivo general de la presente comunicación es presentar la estructura del importante módulo de igualdad de género diseñado para su aplicación en el Programa de Experiencias Mixtas de Formación y Empleo (EMFE) así como en futuras Escuelas Taller y Talleres de Empleo. Precisamente a partir de este programa EMFE impulsado por la Consejería de Empleo de la Junta de Andalucía se elaboró, se diseñó y planificó un módulo de igualdad de género a impartir con carácter obligatorio en este tipo de Programas (Enseñanza no reglada) incentivando prácticas educativas dotadas de continuidad y coherencia en un intento de contribuir a la mejora de la convivencia social con el compro miso de construir una sociedad más abierta, inclusiva y plural, que respete la diferencia, que garantice la libertad de expresión y fomente la igualdad real entre mujeres y hombres. Este hecho es el punto de partida del taller de Educación de género en la enseñanza no reglada, a la hora de poner en marcha sus estrategias de innovación e intervención para la consecución de la igualdad entre hombres y mujeres, desde el cual somos conscientes de la importancia que tiene la actuación para que el principio de igualdad para mujeres y hombres sea una realidad. El rigor con el que el taller incorpora el principio de igualdad queda patente en su línea de investigación-acción en la práctica.Eje 9: Educación y géneroFacultad de Humanidades y Ciencias de la Educació

Predicting the physicochemical properties and geographical ORIGIN of lentils using near infrared spectroscopy

[EN]Calibration statistical descriptors for both whole and ground lentils using Near Infrared Spectroscopy (NIRS), combined with fiber-optic probe, are presented and discussed. The models were developed for estimating the weight, size, total raw protein, moisture, total fat, total fiber, and ash. Standard methods were used to determine compositional parameters of 42 samples of different varieties of lentils. The calibration curves show a wide range of validity for all parameters. The results showed excellent predictability for the determination of weight, fiber, and ash in whole lentils. However, size, moisture, and total fat were predicted satisfactorily in ground lentils. The total protein content could be predicted for both whole and ground lentils. Moreover, NIRS and Direct Partial Least Squares (DPLS) were used to determine whether a sample of lentils belonged to the Protected Geographical Indication (PGI) “Lenteja de La Armuña” or not. The results showed that 95% of the samples were correctly classified as belonging to a PGI. This result demonstrates that this technique allows the differentiation of samples from nearby regions
