“…However, B fertilization was observed to increase the number of new leaves in Prunus persica (L.) Batsch. seedlings, and mobility of B within the plant after leaf application has been observed (Souza et al, 2012). Sá et al (2014) observed that B soil application increased its concentration in the fruits and leaves of Malus domestica more efficiently compared with leaf application.…”

Cagaita (Eugenia dysenterica DC.) is a native fruit tree with high economical potential from the Brazilian Cerrado. However, little is known about the essential nutritional demands of its seedlings. To determine the nutrient demands of Cagaita, a greenhouse experiment was performed, in which plants were grown under hydroponic condition to assess the growth (length and diameter of stems, number of leaves, number of nodes, volume and length of roots, area of the leaf and crown and total dry weight of the leaves, stems and roots) and nutrient concentration (N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn) at different time points after the plant were transferred into a nutrient solution. The seedling growth presented linear behavior until 180 days after transplantation. The total plant dry weight was 6.54 g after 180 days of transfer into the nutrient solution. The N content was positively correlated with the total dry weight and leaf area, whereas B was negatively correlated with the length of the stem and number of leaves. Macro and micronutrient concentrations presented the following order: N>Ca>K>P>Mg>S, Fe>Mn>B>Zn>Cu. A principal component analysis of the different sampling times provided important information used to define the growth variables.

“…However, the B transport in plants also involves other nutrients and compounds. As an example, the investigation of the phloem solution in some translocating species of B revealed substantial levels of polyols, which are able to form complexes with B (B-polyol) and promote the phloem transport of B over relatively long distances in plants (BROWN;SHELP, 1997;SOUZA;CANESIN;BUZETTI, 2012). However, in this work the phloem solution of the cherry tomato was not characterized and, therefore, it is not possible to affirm whether the nutritional status in K influenced the synthesis of polyols.…”

The retranslocation of boron is influenced by the nutritional status of cherry tomato plants

Boron (B) retranslocation may confer greater tolerance to B deficiency or toxicity, resulting in plants and fruits with better nutritional quality. Most plants do not demonstrate phloem mobility for B; however, some plants have natural mobility and others express it under stress conditions, such as nutritional stress. Therefore, we investigated the phloem mobility of B in cherry tomato plants with different nutritional status. The plants were cultivated in nutrient solution with adequate and insufficient doses of Potassium (K) and B. Furthermore, the plants received foliar fertilization with B in a mature leaf (F) in a localized form. The B content and amount in leaves near F were compared with leaves of the same age and position on control plants. The experiment was carried out in a protected environment and conducted in a randomized complete block design in a subdivided plot scheme with four replicates. Re-translocation of B between neighboring leaves was observed when the plant was without K deficiency and with B deficiency. In this nutritional status, leaves next to fertilized leaf with B (F) showed higher B amount when compared to leaves of the same position of control plants. Evidence suggests that retranslocation of B over relatively short distances (between leaves) can be influenced by the nutritional status the cherry tomato plants.

“…Al respecto Dechen; Nachtigall (2006) y Souza et al (2012) citan que, en general, la parte aérea de las plantas presentan mayor concentración de boro que las raíces y esto es porque, está asociado a que posee mayor movilidad del boro en el xilema en comparación al floema. Resultados similares de 136.…”

“…En esta investigación los valores encontrados fueron superiores, probablemente debido a las fuentes de boro utilizadas. Por otro lado, los valores foliares están semejantes a los verificados por Villas Bôas et al (2002), trabajando con naranja 'Valência' fertirrigada (78 mg/kg de boro) y superiores a los constatados (45 mg/kg de boro) por Souza et al (2012), trabajando con movilidad del boro en plantas de durazno.…”

RESUMENEl camu camu es una planta arbustiva que destaca por su alto contenido de Vitamina C. A pesar de los avances tecnológicos en el manejo del cultivo, aún hay insuficiente información sobre el manejo nutricional de las plantas en producción. El objetivo de este trabajo fue determinar el efecto del boro en la producción del fruto de camu camu en suelos aluviales de Ucayali. Utilizamos un diseño de bloques completos al azar (DBCA) con 3 bloques y 8 plantas por unidad experimental. Los tratamientos fueron: T1-Testigo; T2-Fertibagra 15L; T3-Ulexita 40 y T4-Fertibagra 21. Evaluamos la concentración de boro en las plantas antes y después de su aplicación y la producción de frutos en kg/planta. Con relación al análisis de la concentración de boro en la planta, se observó que hay mayor concentración de este micronutriente, en la parte aérea, obteniendo valores máximos en las hojas y tallos. La producción de fruta en kg/planta fue mayor para los tratamientos que incluían fuentes de boro en comparación con el tratamiento de control sin boro. Estos resultados demuestran que las aplicaciones de boro vía suelo y foliar aumentan la concentración de este micronutriente en las diferentes partes de la planta de camu camu, haciendo que las plantas respondan positivamente a la producción de frutos. PALABRAS CLAVE:Myrciaria dubia, vitamina C, fertibagra, ulexita, nutrición mineral. SOURCES OF BORON IN THE PRODUCTION OF THE FRUIT OF CAMU CAMU IN ALLUVIAL SOILS OF UCAYALI ABSTRACTCamu camu is a shrubby plant that stands out for his high content of Vitamin C. Despite of the technological advances in crop management, there is still insufficient information on nutritional management of plants in production. The aim of this study was to determine the effect of boron in the production of the fruit of camu camu in the alluvial soils of Ucayali. We used a completely randomized design of blocks with 3 blocks and 8 plants per experimental unit. The treatments were: T1-Control; T2-Fertibagra 15L; T3-Ulexita 40; and T4-Fertibagra 21. We evaluated the concentration of boron in plants before and after application, and the production of fruits in kg/plant. Regarding the analysis of the contration of boron in the plant,it was observed that there is a greater concentration of this micronutrient in the aerial part, with the highest values reported in the leaves and stems. Fruit production in kg / plant was higher for treatments that included boron sources compared to the control without boron. These results show that boron applications via soil and foliar increase the concentration of this micronutrient in different parts of the plant of camu camu, making the plants respond positively to fruit production. KEYWORDS:Myrciaria dubia, vitamin C, fertibagra, ulexita, mineral nutrition, IIAP. FOLIA Amazónica INTRODUCCIÓNEl camu camu es una planta arbustiva de la familia Myrtaceae que destaca por su alto contenido de Vitamina C, se desarrolla en suelos inundables y se adapta bien a los suelos de altura de la Amazonía peruana. Debido a las condiciones p...
