- Abstract
Maize is a major irrigated crop in Mediterranean areas and its typical intensive management may impact soil nitrous oxide (N2O) emissions. In these irrigated continuous maize systems, the legumes incorporation as well as adjusted nitrogen (N) fertilization might be interesting strategies to reduce soil N2O emissions. The objective of this study was to assess the impact of cropping diversification and different N rates on soil N2O emissions in flooded irrigated maize under Mediterranean conditions. To achieve this, two cropping systems (maize monoculture system, MC; and pea -maize rotation, MP) and 3N rates (unfertilized, 0N; medium rate, MN; and high rate, HN) were evaluated in a field experiment established in NE Spain during 2 years (2019; 2020). During the studied period, the N rate had a significant effect on soil N2O emissions, with a non-linear positive response of cumulative soil N2O emissions to N rates. In both systems, quick and high increases of soil N2O fluxes were observed immediately after the N application reaching 55 and 100 mg N2O-N m−2 day−1 in MC and MP, respectively. Both years, the pea phase of the MP rotation showed greater cumulative N2O emissions than the fallow of MC. However, N2O losses in the maize phase were similar (2019) or even higher (2020) in MC than in MP. Moreover, in both seasons, the MN treatments showed lower yield-scaled N2O emissions and N emission factor than the HN treatments, being this last lower than 1% in all cases. The results obtained showed that in irrigated Mediterranean conditions the replacement of a fallow by a legume, together with an adjusted N fertilization are favourable strategies to mitigate soil N2O emissions in high-yielding maize systems.

- Abstract
In croplands, the adoption of certain management practices may increase soil organic carbon (SOC) levels. In this study, we evaluated the short-term impact of crop stover management and the interaction between crop stover and irrigation method on SOC change in a continuous maize (Zea mays L.) system in Spain. Four years after the beginning of the experiment, total SOC and C fractions (particulate organic matter carbon, POM-C; and mineral-associated organic matter carbon, Min-C) contents, SOC stocks and SOC stock changes were measured in four different soil layers (0−5, 5−10, 10−25 and 25−50 cm) in an experiment with two irrigation methods (sprinkler and flood) and three stover management systems (conventional tillage with all the stover incorporated, CT; no-tillage maintaining the stover, NTr; and no-tillage removing the stover, NT). Stover management resulted in significant differences in SOC and POM-C but not in Min-C. In particular, NT reduced SOC and POM-C contents compared with CT and NTr (about 10 and 60 %, respectively). After 4 years, SOC change was not affected by the interaction between stover management and irrigation. Concurrently, both CT and NT showed SOC losses, reaching 0.11 and 1.22 Mg ha−1 yr−1 in CT and NT, respectively. However, NTr showed SOC gains at a rate of 0.09 Mg ha−1 yr−1. Consequently, the removal of crop stover has been demonstrated as a detrimental strategy to store SOC in the short-term in irrigated continuous maize systems.

- Abstract
Aim of study: Developing models to determine soluble solids content (SSC) in cherry trees by means of Vis/NIR spectroscopy. Area of study: The Spanish Autonomous Community of Aragón (Spain). Material and methods: Vis/NIR spectroscopy was applied to Prunus avium fruit ‘Chelan’ (n=360) to predict total SSC using a range 400-2420 nm. Linear (PLS) and nonlinear (LSSVM) regression methods were applied to establish prediction models. Main results: The two regression methods applied obtained similar results (Rcv2=0.97 and Rcv2=0.98 respectively). The range 700-1060 nm attained better results to predict SSC in different seasons. Forty variables selected according to the variable selection method achieved Rcv2 value, 0.97 similar than full range. Research highlights: The development of this methodology is of great interest to the fruit sector in the area, facilitating the harvest for future seasons. Further work is needed on the development of the NIRS methodology and on new calibration equations for other varieties of cherry and other species.

- Abstract
A principal components analysis (PCA) carried out on the L*, a* and b* color coordinates, allows a good discrimination among maturity stages of the ‘Cashmere’ sweet cherry cultivar. Physical-chemical parameters were determined by conventional destructive methods that were used as a reference to compare with statistically treated optical data. The study was carried out during two consecutive campaigns 2010 and 2011. Samples were taken at optimum harvest time following the criteria of firmness, soluble carbohydrates and expert visual estimation of color. In the first season, two other samples of 200 fruits each, were picked at random in the plot from several trees, a week before and a week after the estimated optimal date. In 2011, sampling was made as in 2010 but timing was as follows: two days before harvest, at harvest and 2 and 4 days after. In both seasons, a simple representation of fruit color in the a* b* space of the whole set of samples in a single year, did not permit differentiation of fruits on a maturity stage basis. However, a principal component analysis including not only a* and b* but also the luminosity L*, allowed the classification of fruits according their ripeness using only the first component PC1. This work demonstrates that a simple colorimeter can be a suitable alternative to destructive methods to determine the optimum harvest time and also may permit the prediction of the shelf life of this commodity (very short indeed, 1 week approximately).

218 Pags.- 18 Tabls.- 32 Figs., [ES] Aragón cultiva el 30% de la superficie total de frutales de España. Unas 50.000 ha dibujan el paisaje frutícola de Aragón. La demanda de calidad por parte de consumidores, agricultores, centrales hortofrutícolas es cada vez más exigente. Tradicionalmente, el control de calidad, se realiza con técnicas que destruyen el fruto y otras subjetivas, que incluyen la estimación visual del aspecto del fruto. Sin embargo, estás técnicas ralentizan el proceso de selección en Central no son suficientemente representativas de la población muestreada, además de constituir un gasto elevado por la fruta destruida., Estos factores han impulsado el desarrollo de técnicas más rápidas y menos costosas, que puedan aplicarse a la mayoría de los frutos procesados y que reflejen el estado interno y externo de calidad del fruto. Las llamadas técnicas ópticas, se basan en medir la interacción de la luz con la materia, en este caso la fruta y permiten determinar en una sola medida varios parámetros físico-químicos del fruto, como firmeza y contenido en sólidos solubles totales. Entre estas técnicas cabe destacar la Espectroscopia de Infrarrojo Cercano y el Análisis de Imágenes Multiespectrales, que hemos utilizado en este trabajo., Para poder relacionar los datos obtenidos por estas técnicas con los índices de madurez del fruto, es necesario construir modelos de calibración. Los métodos elegidos de regresión lineal (PLS) y no lineal (LS-SVM) proporcionan buenos resultados ya que permiten predecir el estado de madurez de la fruta a partir de la señal óptica obtenida de cada fruta., Las técnicas ópticas proporcionan un elevado número de variables (tantas como longitudes de onda registradas de los espectros), entre las que existe una gran colinealidad e información irrelevante. En este trabajo, nos hemos planteado realizar una selección de variables con el fin de elaborar modelos de calibración más sencillos que puedan ser aplicados en las líneas de selección de las centrales hortofrutícolas., [EN] More than 30% of the surface devoted to fruit production in Spain corresponds to Aragon. Around 50, 000 ha constitute the landscape of fruit tree production of Aragón. Fruits and vegetables of high quality properties are increasingly required by consumers, and consequently by producers and by the rest of agro food chain. Traditionally, test of quality are performed by techniques which imply whether the destruction of the sample (fruit) or other subjective non-quantitative methods as the estimation of external visual appearance. In general, these techniques slow down the selection processes; do not provide enough representatively of the whole sample population and also imply the waste of considerable amounts of the facilities used to monitor strictly quality., Among others, all these facts led to the development of new techniques which include very short times of measurement and less expensive equipment in order to facilitate their inclusion into the selection lines at industrial level. The so called optical techniques are based on the measurement of the interaction between the light and the living sample, the fruit in our case, and from a single measurement several physical-chemical parameters of the fruit, as total soluble solids and firmness, can be estimated or calculated., Near Infrared Spectroscopy and Multispectral Images Analysis are the optical techniques used in this work., Statistical models are created to relate optical information with reference values obtained by conventional destructive methods. Linear regression (PLS) and nonlinear regression (LS-SVM) models where selected among others as we demonstrate that provide very good results to predict the stage of maturity by using optical signals obtained from each fruit. However, optical techniques produced a large number of variables, many of them with high collinearity and also huge amounts of irrelevant information. One of the achievements of this work has been the development of a variable selection procedure, which allows the development of simpler calibration models., Este trabajo ha sido financiado con los proyectos de investigación: Nuevas estrategias para evitar el desarrollo de calciopatías en cultivos frutales modelo (AGL2009-08501).

Firmness ,Peaches ,NIR ,Acoustic system - Abstract
16 p., 2 fig., 2 tab., In this work, near infrared spectroscopy (NIR) and an acoustic measure (AWETA) (two non-destructive methods) were applied in Prunus persica fruit ‘Calrico’ (n=260) to predict Magness-Taylor (MT) firmness. Separate and combined use of these measures was evaluated and compared using PLS and LS-SVM regression methods. Also, a Mutual Information (MI)-based variable selection method, seeking to find the most significant variables to produce optimal accuracy of the regression models, was applied to a joint set of variables (NIR wavelengths and AWETA measure). The newly proposed combined NIR-AWETA model gave good values of the determination coefficient (R2) for PLS and LS-SVM methods (0.77 and 0.78, respectively), improving the reliability of MT firmness prediction in comparison with separate NIR and AWETA predictions. The three variables selected by the variable selection method (AWETA measure plus NIR wavelengths 675 and 697 nm) achieved R2 values 0.76 and 0.77, PLS and LS-SVM. These results indicated that the proposed MI-based variable selection algorithm was a powerful tool for the selection of the most relevant variables.

4 Pags., 2 Tabls., La aplicación de la regresión por mínimos cuadrados parciales (PLS) nos ha permitido obtener correlaciones entre el espectro de reflectancia visible-infrarrojo (310-1145 nm) y las medidas convencionales de firmeza en melocotón tardío de Calanda de la variedad “Calrico”. Dividiendo la muestra en dos grupos aleatorios, hemos realizado, previamente a la aplicación de PLS, dos tratamientos matemáticos distintos, de los que uno da mejores resultados que el otro. La ecuación de calibración obtenida permite una determinación muy rápida de la firmeza a partir del espectro, sin destrucción de la muestra, Este trabajo ha sido financiado por el proyecto de investigación: AGL2009- 08501/AGR (Programa Nacional de Proyectos de Investigación Fundamental).

Un conjunto de tareas de conciencia fonológica, identificación y discriminación de fonemas y juicios de orden temporal fue administrada a una muestra de niños disléxicos y sus respectivos grupos de control edad (CE) y control nivel lector (CNL). Los estímulos de las tareas de identificación y discriminación fueron nueve sílabas de un contraste de lugar de articulación en el continuo /ba-da/, construidas mediante la manipulación de los formantes 2 y 3. Los datos fueron analizados siguiendo dos métodos. Las comparaciones ANOVA mostraron diferencias significativas en las tareas de discriminación y juicio de orden temporal entre los disléxicos y los grupos controles, mientras que los parámetros de la tarea de identificación (pendiente y límite categorial) no alcanzaron la significación. Se desarrolló también un procedimiento para evaluar la desviación. El 44% de los niños disléxicos mostraron al menos dos medidas con una desviación estándar de 1.65. Además, hubo una relación entre las ejecuciones en conciencia fonológica y percepción del habla. En general los resultados fueron muy similares a los principales hallazgos descritos en la bibliografía. Por tanto, defendemos que las medidas procedentes de las tareas de percepción del habla podrían ser incorporadas como un elemento complementario en el procedimiento de diagnóstico de la dislexia evolutiva. A set of phonological awareness, phoneme identification, discrimination and temporal order tasks were administered to dyslexic children and chronological age (CA) and reading-level (RL) comparison groups. The identification and discrimination task stimuli consisted of nine /ba-da/ syllables over an articulation continuum. Syllables were obtained by manipulating formants 2 and 3. Data were analyzed using two methods. ANOVA comparisons showed significant differences between the dyslexic and control groups in the discrimination and temporal order tasks, whereas parameters from the identification task (slope and boundary) did not reach significance. A procedure to assess deviance was also developed. 44% of dyslexic children showed at least two 1.65 standard deviation measures. Moreover, there was an association between phonological awareness and speech perception performance. Generally, the results were similar to the main findings described in the literature. Thus, we suggest that measures from speech perception tasks could be incorporated as complementary elements in developmental dyslexia diagnosis procedures.

The so called optical techniques are based on the measurement of the interaction between the light and the living sample, the fruit in our case, and from a single measurement several physical-chemical parameters of the fruit, as total soluble solids and firmness, can be estimated or calculated., Near Infrared Spectroscopy and Multispectral Images Analysis are the optical techniques used in this work., Statistical models are created to relate optical information with reference values obtained by conventional destructive methods. Linear regression (PLS) and nonlinear regression (LS-SVM) models where selected among others as we demonstrate that provide very good results to predict the stage of maturity by using optical signals obtained from each fruit. However, optical techniques produced a large number of variables, many of them with high collinearity and also huge amounts of irrelevant information. One of the achievements of this work has been the development of a variable selection procedure, which allows the development of simpler calibration models.

- Abstract
In this work, near infrared spectroscopy (NIR) and an acoustic measure (AWETA) (two non-destructive methods) were applied in Prunus persica fruit ‘Calrico’ (n=260) to predict Magness-Taylor (MT) firmness. Separate and combined use of these measures was evaluated and compared using PLS and LS-SVM regression methods. Also, a Mutual Information (MI)-based variable selection method, seeking to find the most significant variables to produce optimal accuracy of the regression models, was applied to a joint set of variables (NIR wavelengths and AWETA measure). The newly proposed combined NIR-AWETA model gave good values of the determination coefficient (R2) for PLS and LS-SVM methods (0.77 and 0.78, respectively), improving the reliability of MT firmness prediction in comparison with separate NIR and AWETA predictions. The three variables selected by the variable selection method (AWETA measure plus NIR wavelengths 675 and 697 nm) achieved R2 values 0.76 and 0.77, PLS and LS-SVM. These results indicated that the proposed MI-based variable selection algorithm was a powerful tool for the selection of the most relevant variables.

- Abstract
1 copia (a-3) del póster original presentado. 3 Figs., 1 Tabl., To determine fruit quality traits, non-destructive methods like near infrared spectroscopy are displacing traditional procedures. The interpretation of NIR spectra. involves a complex statistical analysis as the whole spectrum is used to obtain the calibration equations which permit to assess some quality traits already determined by destructive methods, such as a texturometer for rheological properties or a refracto meter for total soluble solids content .

[SPA] Dos variedades de naranja, cv "Salustiana" y cv "Valencia", se conservaron bajo distintas condiciones de temperatura (Tª), humedad relativa (HR), y atmósfera controlada (AC). Las naranjas cv "Salustiana" se mantuvieron durante 93 días en tres cámaras frigoríficas en las siguientes condiciones: ∼4ºC-70%HR-4%O2-2,5%CO2, ∼6ºC-∼85%HR- 21%O2-4%CO2, ∼4ºC-∼85%HR-21%O2-4%CO2. Las naranjas cv. "Valencia" se mantuvieron en tres cámaras frigoríficas durante 153 días en cajas de tamaño industrial empleando las siguientes condiciones de Tª, HR y AC: ∼3ºC-∼85%HR-21%O2-2,5%CO2, ∼3ºC-∼85%HR- 21%O2-0,6%CO2, y ∼3ºC-∼85%HR-21%O2-1%CO2. En esta nueva experiencia el porcentaje de CO2 fue reduciéndose a lo largo del periodo de conservación. Durante el almacenamiento el zumo exprimido en una industria de zumo procedente de las diferentes muestras se analizó para determinación de sólidos solubles, acidez, rendimiento y diferencia de color. Los sólidos solubles disminuyeron a HR bajas y la acidez disminuyó con cambios bruscos y continuos de los niveles de CO2. El rendimiento fue menor al final del periodo de almacenamiento y la diferencia de color aumentó conforme se prolongaba la conservación. Se presentan resultados de ambas experiencias. [ENG] Two types of orange, cv "Salustiana" and cv "Valencia", were stored under different temperature (T), relative humidity (RH), and controlled atmosphere (CA) conditions. "Salustiana" oranges were stored in three cold store rooms during 93 days under the following conditions: ∼4ºC-70%RH-4%O2-2.5%CO2, ∼6ºC-∼85%RH-21%O2-4%CO2, and ∼4ºC-∼85%RH-21%O2-4%CO2. "Valencia" oranges were stored in three cold store romos during 153 days into industrial type of boxes under new cold storage (T, RH, CA) conditions: ∼3ºC-∼85%RH-21%O2-2.5%CO2, ∼3ºC-∼85%RH-21%O2-0.6%CO2, and ∼3ºC-∼85%RH- 21%O2-1%CO2. In this new model the percentage of CO2 was decreased during the storage. During the storage each sample was squeezed in a juice industry where brix degrees, acidity, orange yield for juice and difference of color were determined. Soluble solids decreased under low-level RH and the acidity decreased with suddenly changes in the concentration of CO2. The orange yield for juice was lesser at the end of the storage and the difference of color increased during the storage. The results from both works are showed.

[ENG] Two types of oranges, cv "Salustiana" and cv "Valencia", were stored under different temperature (T), relative humidity (RH), and controlled atmosphere (CA) conditions. Five postharvest treatments were carried out with "Salustiana" oranges: thiabendazol, imazalil, ortophenilphenol, hot water dip (45ºC) with sodium bicarbonate and a mixture of imazalil, ortophenilphenol and guazatine acetate. Then a wax was applied and finally the oranges were stored in three store rooms during 93 days. Two postharvest treatments were carried out with "Valencia" oranges without wax application: imazalil and a mixture of imazalil and thiabendazol, then the oranges were stored in three cold store rooms during 153 days into industrial type of boxes. Control samples without any treatment were reserved during the storage. Penicillium italicum, Penicillium digitatum, Geotrichum, Alternaria spp, Botrytis and other decays were identified during the storage in the orange samples. The percentage of decays increased during the storage nevertheless the percentages obtained were satisfactory even with the strong-less treatments.

[SPA] El estudio se realizó con naranjas cv "Navelina" en el IFAPA (Centro de Palma del Río). El material utilizado para los envases fue una mezcla de poliéster saranizado y polietileno. Las naranjas se lavaron y fueron sometidas a un baño de agua caliente para así facilitar el pelado. Seguidamente las naranjas se cortaron por la mitad y a la mitad de ellas se le aplicó una disolución de sorbato potásico al 0,2%. Se usaron dos formatos de envase, uno grande con cuatro mitades de naranja pelada y otro pequeño con dos mitades de naranja pelada. Se emplearon diferentes combinaciones de atmósfera de envasado: 5% O2 -5% CO2; 5% O2-10% CO2 y 5% O2-15% CO2. Las muestras se almacenaron en la misma cámara frigorífica a 4ºC y 85% de humedad relativa. Durante el almacenamiento se realizaron 4 controles en 30 días más un control inicial. En cada control se realizaron determinaciones de Brix, Acidez tritable, y recuentos microbiológicos de mohos y levaduras y de aerobios mesófilos. Se obtuvieron alzas en Brix, la Acidez disminuyó y los recuentos de microorganismos fueron muy bajos detectándose influencia de la mezcla de gases empleada; del formato de envasado, y del tratamiento aplicado. [ENG] This work was carried out with cv “Navelina” oranges by IFAPA (Centre of “Palma del Rio”). Plastics with a mixture of polyester saranized and polyethylene were used. The oranges were washed and dipped into hot water to facilitate the peeling off operation. Then oranges were cut into equal portions and one portion was treated with a solution of potassium sorbate (0.2%). Two plastics format were used, a big-one with four portions of orange and a small-one with two portions of orange. Three different atmosphere combinations were used: 5% O2 -5% CO2; 5% O2-10% CO2 y 5% O2-15% CO2. The samples were stored in the same store room at 4ºC and 85% RH. During the storage (30 days) 4 checkpoints and a initial chechpoint were carried out. Analysis of Brix, Tritable Acidity and microbiological counts of moulds, yeasts and mesophilos aerobics were carried out in each checkpoint.

- Abstract
The objective of this study was to evaluate in ‘Smoothee Golden Delicious’ apples, the use of backscattering images as a non-destructive method to estimate some quality parameters during the ripening process of fruits. In this experiment, 208 apples were collected from an experimental orchard of the Estación Experimental de Aula Dei (CSIC) in Zaragoza (Northeastern, Spain). Backscattering images were kept from samples picked up every 15 days during 7 months until harvest. In the same fruits, soluble solids contents (SSC) and firmness were measured by traditional destructive methods. The light source was a solid state laser diode module emitting at three different spectral bands (670, 785 and 980 nm) PLS calibration methods were used to create the statistical model to predict SSC and firmness. Good results were obtained when PLS calibration was applied to Feret diameter corresponding at different levels of gray. The Rcv2 values were 0.87 for firmness and 0.93 for SSC, which are higher than other reported in the literature for the same commodity.

- Abstract
A set of phonological awareness, phoneme identification, discrimination and temporal order tasks were administered to dyslexic children and chronological age (CA) and reading-level (RL) comparison groups. The identification and discrimination task stimuli consisted of nine /ba-da/ syllables over an articulation continuum. Syllables were obtained by manipulating formants 2 and 3. Data were analyzed using two methods. ANOVA comparisons showed significant differences between the dyslexic and control groups in the discrimination and temporal order tasks, whereas parameters from the identification task (slope and boundary) did not reach significance. A procedure to assess deviance was also developed. 44% of dyslexic children showed at least two 1.65 standard deviation measures. Moreover, there was an association between phonological awareness and speech perception performance. Generally, the results were similar to the main findings described in the literature. Thus, we suggest that measures from speech perception tasks could be incorporated as complementary elements in developmental dyslexia diagnosis procedures., Un conjunto de tareas de conciencia fonológica, identificación y discriminación de fonemas y juicios de orden temporal fue administrada a una muestra de niños disléxicos y sus respectivos grupos de control edad (CE) y control nivel lector (CNL). Los estímulos de las tareas de identificación y discriminación fueron nueve sílabas de un contraste de lugar de articulación en el continuo /ba-da/, construidas mediante la manipulación de los formantes 2 y 3. Los datos fueron analizados siguiendo dos métodos. Las comparaciones ANOVA mostraron diferencias significativas en las tareas de discriminación y juicio de orden temporal entre los disléxicos y los grupos controles, mientras que los parámetros de la tarea de identificación (pendiente y límite categorial) no alcanzaron la significación. Se desarrolló también un procedimiento para evaluar la desviación. El 44% de los niños disléxicos mostraron al menos dos medidas con una desviación estándar de 1.65. Además, hubo una relación entre las ejecuciones en conciencia fonológica y percepción del habla. En general los resultados fueron muy similares a los principales hallazgos descritos en la bibliografía. Por tanto, defendemos que las medidas procedentes de las tareas de percepción del habla podrían ser incorporadas como un elemento complementario en el procedimiento de diagnóstico de la dislexia evolutiva.
