“…As shown in Table 2-3, both nitrate and total N concentration was the highest in NaC l0 KN 15 treatment and decreased as the salinity increased. In general, the results suggest that high salinity causes a depression in NO 3 and N concentration and K/Na ratio. Raising of KN from 0 to 10 mM in the solution increased NO 3 concentration in the leaves, however it was ineffective at 15 mM KN in restoring the decreased in the leaf NO 3 caused by the increased salinity.…”

“…Present data clearly demonstrated that negative relationship between NO 3 and Cl as it has been previously reported [21,32] . It implies that addition to the growth media of KN above what would be considered sufficient for optimal growth in the absence of salinity, decreased Cl concentration to the extent that canopy injury was reduced, thereby lessening growth inhibition [3] . Toxicity symptoms such as dead leaf edge and drop were recorded at NaCl 60 treatment, which was the highest at 15 mM KN concentration in both soil and foliar applications.…”

“…It is well known that addition supply of Ca or NO 3 to salt stressed plants improves the tolerance to salinity [13,22,31] . However, there is little information available about the effect of the increased KNO 3 (KN) at the saline conditions on the salinity tolerance of perennial ryegrass. Therefore, the aim was the investigation of the combined effect of K and NO 3 on perennial ryegrass to elucidate responses to NaCl at different rates of supplemental KN.…”

Abstract:Two experiments were conducted to determine the effect of KNO3 application on perennial ryegrass salinity tolerance. Two NaCl levels (0 and 60 mM) factorially combined with four KNO3 (KN) levels (0, 5, 10 and 15 mM) as the treatments. The KN was applied either to the soil or foliarly sprayed. The results showed that in both experiments the increased salinity significantly reduced the vegetative characteristics of ryegrass. In the salinity treatment, supplying KN at 10 mM concentraion increased the fresh and dry weight as well leaf area, however, the growth of the plants was lower at the 0 and 15 mM concentration of KN. The concentration of N, NO3, P and K was reduced in the salinity treatments, but the concentration of Na and Cl was increased. Salinity (NaCl60) significantly reduced the K/Na ratio, while it was increased when the KN was increased in the solution. The concentration of Cl was significantly reduced when KN increased in the solution so that its concentration in NaCl60 and 0 mM KN was 75% in soil and 66.6% in foliar sprays treatment, respectively, higher than that in NaCl60 and 15 mM treatment. Combination of both salinity and KN concentration remarkably increased the proline content. The concentration of chlorophyll was reduced in NaCl60 treatment however; additional supplying of KN increased the chlorophyll concentration. In NaCl60 treatment, the highest survival plants were observed at 10 mM KN as either foliar or soil application. It seems that the reduced Cl concentration, increased proline and K/Na ratio were the main reason for the improved tolerance for salinity of the perennial ryegrass in the 10 mM KN concentration.

“…Otros autores han constatado asimismo reducciones en la concentración de este elemento al incrementar el aporte de N en cítricos. Bar et al (1997) cultivados en un suelo arenoso observaron un decremento en los niveles foliares de boro de ambos patrones al aumentar la concentración de nitrato en la solución nutritiva de 2 a 16 mM en plantas sometidas a estrés salino. De manera recíproca, Rajaie et al (2009) han estudiado la respuesta en el crecimiento y composición mineral de plantones de limonero cultivados en un suelo con diferentes concentraciones de boro (0-2,5-5-10-20 µg·g -1 suelo); la máxima absorción de nitrógeno se presentó con las concentraciones bajas de este elemento (2,5 µg B·g -1 suelo).…”

Dª Belén Martínez Alcántara, Ingeniera Agrónoma, ha realizado bajo nuestra dirección el trabajo que, con el título "Estudio de la absorción y translocación del nitrógeno en cítricos en función del aporte estacional del abono nitrogenado, mediante la técnica de dilución isotópica", presenta para optar al grado de Doctora Ingeniera Agrónoma.Para que así conste a los efectos oportunos, firman el presente documento en Moncada a 9 de marzo de 2010. Fdo. D. Francisco Legaz Paredes Fdo. Dª Ana Quiñones OliverA mis padres... AGRADECIMIENTOSAntes de poner el punto final a este documento, me gustaría dejar constancia del apoyo recibido, que de forma directa o indirecta tanto me ha ayudado en esta etapa, y del que sin duda me siento especialmente orgullosa.En primer lugar, mi agradecimiento es para mis directores de tesis, el Dr. Francisco Legaz, por su dedicación, por ser ejemplo de minuciosidad y perfeccionismo, gracias por todo el tiempo dedicado; a la Dra. Ana Quiñones, por su apoyo durante estos años, por su continuo ánimo y ayudarme a ver siempre el lado positivo. Gracias por la confianza que depositasteis en mí, pero sobre todo, gracias por vuestro cariño.Por supuesto, todo este trabajo no habría sido posible sin los compañeros delDepartamento de Citricultura, gracias por vuestra ayuda en los interminables arranques y en el día a día. A Pepa, gracias porque desde el primer momento has velado por mi y lo sigues haciendo; a Tere, por tu ironía y múltiples refranes; a Mª Carmen Prieto, por tu apoyo y comprensión y por los buenos momentos compartidos. A Bati, por la ayuda en el A Ángeles Calatayud, mi madrina de FIA, gracias por tu ayuda pero especialmente por tu apoyo e interés en todo momento. A Ramón Redondo, María de Castro y Fernando de la Rubia, por ser "el teléfono de la esperanza" en los momentos difíciles con la espectrometría de masas. A Emilio Carbonell y Jordi Pérez, por hacer "fácil" la estadística.A mis amigos, muy especialmente a mis incondicionales, Carolina y María, que habéis seguido con interés cada uno de mis pasos, animándome continuamente, me siento muy afortunada. A Pablo, porque se que puedo contar contigo.A Bosco, por tu infinita paciencia, por escucharme una y otra vez, por animarme siempre, aunque te lo haya puesto especialmente difícil este último año; y porque sí, sí que te lo imaginas…quién si no.A mi familia. A Jose Luis, que has seguido semanalmente mi evolución. A mi hermano, porque siempre estás ahí. Y sobre todo, y muy especialmente, a mis padres, porque si he llegado a completar este proceso ha sido, sin duda, gracias a vosotros.La verdadera ciencia enseña, por encima de todo, a dudar y a ser ignorante. Miguel de Unamuno RESUMENUna fertilización nitrogenada racional debe contemplar no sólo el aporte de una dosis ajustada a las necesidades del cultivo, sino que a su vez debe considerar la correcta distribución de ésta durante el periodo de abonado. Sin embargo, no se dispone de suficiente información del efecto que la distribución estacional del fertilizante tiene sobre la absorción y ...
