“…La variable de SST mostró diferencias altamente significativas (p≤ 0.05), donde los tratamientos con 550 g de Fe mostraron los mayores valores de grados Brix con 5.38 (Cuadro 5). El área foliar (AF) del cultivo de jitomate en ambas dosis de Fe se vieron afectadas significativamente, con una mayor área foliar en las dosis altas, superando al testigo en 138%, presentando un área foliar promedio de 2 917 cm 2 , esto fue debido a que la baja concentración de Fe provocó una disminución en los contenidos de clorofila y otros componentes de los cloroplastos lo que disminuyó la capacidad de crecimiento del cultivo, resultados similares fueron encontrados por Incesu et al (2015) en el cultivo de Mandarina; sin embargo, en las diferentes dosis de Zn y Cu fueron estadísticamente similares al testigo (p≤ 0.05) Para las dosis de Zn, el testigo mostró una mayor área foliar seguido de las concentraciones altas, datos contrastantes fueron reportados por Haleema y Hussain (2018) en cultivo de jitomate quienes demostraron que a mayor dosis de Zn mayor fue el área foliar. En Cu se observó que las dosis altas superaron al testigo 63% (Figura 1), dichos resultados contradicen a lo mencionado por Yruela (2005), quien menciona que las plantas con exceso de Cu regularmente presentan una disminución en la biomasa.…”

El jitomate es una de las hortalizas de mayor importancia a nivel mundial, por lo que, conocer el manejo en la nutrición y su interacción en el rendimiento agronómico es importante. El experimento se realizó en un invernadero de baja tecnología, de la Universidad Autónoma Agraria Antonio Narro con el objetivo de determinar el efecto suplementario en diferentes concentraciones de los microelementos Fe, Cu y Zn en el rendimiento agronómico del cultivo de jitomate. Se evaluaron tres factores que consistieron en las aplicaciones suplementarias de fertilizantes a base de Fe, Cu y Zn y dos niveles de concentración para cada caso, además del tratamiento testigo (dosis normal de la solución nutritiva Steiner). Los tratamientos fueron evaluados mediante un diseño completamente al azar con arreglo factorial 3 x 2, con 16 repeticiones por tratamiento. Las dosis bajas de Zn superaron al testigo 27.3% en la variable vitamina C, mientras que, en los sólidos solubles totales, área foliar (AF), relación área foliar (RAF) y área foliar específica (AFE) los niveles altos de Fe superaron al testigo en un 16.4%, 138%, 112% y 44%,

“…Exogenously applied Fe in both forms (Fe-Asp and FeSO 4 ) was found to be effective in ameliorating the adverse impacts of imposed drought stress on the biosynthesis of leaf photosynthetic pigments by decreasing membrane lipid peroxidation that might have improved the leaf photosynthetic efficiency with better growth and yield of water stressed sunflower plants. Previous studies have also reported that the exogenous Fe application improved the stress tolerance by boosting up the plant photosynthetic efficiency of maize [76], sunflower [77] and W. murcott mandarin [78]. Furthermore, it was reported by Sadak et al [78] that foliary-applied Asp increased the stress tolerance of Vicia faba plants associated with improved accumulation of phenolic content, proline, amino acids, total soluble sugars, polyamines, and IAA [79].…”

Different techniques are being employed to reduce the adverse effects of water stress on seed yield and quality of crop plants. The current study aimed to improve the water stress tolerance of field-grown sunflower by foliar-supplied ecofriendly iron-chelated aspartate (Fe-Asp) in comparison with FeSO4. Water stress decreased the plant growth and yield, accompanied with disturbed water relations, nutrient acquisition, accumulation of amino acids, and antioxidative defense mechanisms. However, lipid peroxidation, total anthocyanin, and photosynthetic pigments were increased. Fertigation of FeSO4 and Fe-Asp as foliar sprays proved effective to reduce the negativities of limited irrigation on biomass production and seed yield, accompanied with a reduction in lipid peroxidation and improvements in water relations, antioxidative defense mechanisms, and leaf photosynthetic pigments. In comparison with FeSO4, foliary applied Fe-Asp better improved the plant water relations with more accumulation of essential amino acids and nutrient acquisition, especially leaf aspartate (Asp) and Fe accumulation which showed better translocation. Overall, foliary applied Fe-Asp proved better for induction of drought tolerance in sunflower plants as compared with FeSO4. The study recommended the use of the ecofriendly Fe-Asp as a foliar spray for better growth and production of sunflower under limited irrigation.

“…Iron (Fe) is the fourth most abundant element in the earth’s crust, at 5%, and the soil contains from 1 to 5% (on average 3.2%) Fe. On the other hand, the Fe content in plants is normally only 0.005% [ 6 , 7 ]. Fe is an important elemental nutrient for plants; it not only participates in the synthesis of organelles, such as the chloroplast, mitochondria, and palisade tissues, but also acts as a cofactor for numerous enzymatic processes [ 8 ].…”

Sorbus commixta is a valuable hardwood plant with a high economical value for its medicinal and ornamental qualities. The aim of this work was to investigate the effects of the iron (Fe) source and medium pH on the growth and development of S. commixta in vitro. The Fe sources used, including non-chelated iron sulfate (FeSO4), iron ethylenediaminetetraacetic acid (Fe-EDTA), and iron diethylenetriaminepentaacetic acid (Fe-DTPA), were supplemented to the Multipurpose medium with a final Fe concentration of 2.78 mg·L−1. The medium without any supplementary Fe was used as the control. The pH of the agar-solidified medium was adjusted to either 4.70, 5.70, or 6.70. The experiment was conducted in a culture room for six weeks with 25 °C day and night temperatures, and a 16-h photoperiod with a light intensity of 50 mmol·m−2·s−1 photosynthetic photon flux density (PPFD). Both the Fe source and pH affected the growth and development of the micropropagated plants in vitro. The leaves were greener in the pH 4.70 and 5.70 treatments. The tissue Fe content decreased with the increase of the medium pH. The leaf chlorophyll content was similar between plants treated with FeSO4 and those with Fe-EDTA. The numbers of the shoots and roots of plantlets treated with FeSO4 were 2.5 and 2 times greater than those of the control, respectively. The fresh and dry weights of the shoot and the root were the greatest for plants treated with Fe-EDTA combined with pH 5.70. The calcium, magnesium, and manganese contents in the plantlets increased in the pH 5.70 treatments regardless of the Fe source. Supplementary Fe decreased the activity of ferric chelate reductase. Overall, although the plantlets absorbed more Fe at pH 4.70, Fe-EDTA combined with pH 5.70 was found to be the best for the growth and development of S. commixta in vitro.
