“…Citrus plants are among the most studied fruits in Brazil, with research particularly focused on cultivation and phytosanitation. However, few studies regarding their botanical and physiological properties have been completed (ESPOSTI; SIQUEIRA; CECON, 2008). Such studies are important in order to begin cultivating these species in the São Francisco River Valley region.…”

“…According to Morellato et al (2000), phenological characterization makes it possible to determine when the flowers, seeds, and fruits are available. In order to determine the ideal harvest times for optimal fruit quality, it is important to understand the growing process and fruit development (ESPOSTI; SIQUEIRA; CECON, 2008).…”

“…ResultAdos y discusión inicio de la siguiente (Esposti et al, 2008). La fase 1, un intervalo de aproximadamente dos meses de división celular y lento crecimiento desde la antesis; la fase 2 o de crecimiento rápido, en donde el fruto experimenta un gran incremento en el tamaño por expansión celular y acumulación de agua durante cuatro a seis meses, y, la fase 3 o período de maduración, donde el crecimiento en su mayoría se detiene (Dalal et al, 2013).…”

“…El intervalo de la fase 2 y la fase 3, con participación en el sigmoideo, se delimitan en la figura 3. La fase 3 inició aproximadamente el día 84 de manera coincidente en ambos frutos y la fase 1 no fue estudiada, donde las tendencias de las curvas se asemejan a las curvas de crecimiento de frutos de Citrus reticulata Blanco graficada por Esposti et al (2008) (Cuadro 1; figuras 3 y 4). El fruto mA aunque de menor diámetro, fue el que presentó mejor desarrollo de color (Figura 4) y abscisión más temprana (Cuadro 1).…”

ResumenE l propósito de este trabajo fue usar imágenes digitales para medir el diámetro ecuatorial de frutos de mandarina durante el crecimiento en el árbol para construir curvas de crecimiento. El experimento se realizó en una parcela (9 m x 5 m), ubicada en Valencia (Venezuela) y cultivada con árboles frutales (Acerola, limón, mandarina, palmeras) creciendo naturalmente. Se seleccionaron dos frutos de la parte inferior de la copa (altura del suelo 2.5 m) en crecimiento, de idéntico diámetro ecuatorial (39 mm) y en la cercanía se colocó una referencia fija de medida. Se utilizó una computadora portátil, una cámara digital calibrada y un software de diseño gráfico. El ensayo se llevó a cabo durante 105 días y cada 4 a 5 días se fotografiaron los frutos. Las imágenes captadas se descargaron en la computadora y procesaron con el software CorelDRAW® X3. La medición de los frutos en las imágenes se realizó con una regla graduada virtual creada con el software y con los datos obtenidos se elaboraron curvas de crecimiento. Los dos frutos se comportaron de similar manera durante el crecimiento, con coincidencias en las mediciones los días 58 y 84 (44.25 y 50.50 mm, respectivamente), en este último día, aproximadamente se inició la fase 3, coincidiendo en ambos frutos. Los diámetros ecuatoriales alcanzados a los 105 días fueron 48.50 y 50.75 mm para el fruto 1 y 2, respectivamente. Fueron factibles las mediciones mediante el procedimiento utilizado.Palabras clave: Curvas de crecimiento de frutos, diámetro ecuatorial, mandarina, procesamiento digital de imágenes. AbstRActT he purpose of this work was to use digital images for measuring the equatorial diameter of mandarin fruits during growth on the tree for the construction of growth curves. The experiment was carried out in a plot (9 m x 5 m) with fruit trees (acerola, lemon, mandarin, palms) growing naturally (Valencia, Venezuela). Two fruits during growth from the bottom crown (2.5 m high from the ground) of the tree were selected (equatorial diameter 39 mm), and a fixed reference for measurements was placed nearby. A laptop computer and a CCD digital camera, (calibrated), were used, and graphic design software. Assays were carried out during 105 days and every 4 to 5 days the fruits were photographed. The images were downloaded to computer and processed with the software CorelDRAW® X3. The measurements of fruits in images were done using a virtual graduated rule created with the software, and with the data, growth curves were made. The behaviour of both fruits during growth was similar with coincidences in measurements (day 58: 44.25 mm; day 84: 50.50 mm). The phase 3 started at day 84, approximately, and the equatorial diameters reached at day 105 were for each fruit 48.50 y 50.75 mm. Measurements were feasible by the procedure used.

The objective was to physically and chemically characterize jabuticaba fruits var. ‘Pingo de Mel’ during their development. Some fruits were harvested ten days after flowering (DAF) and harvesting was continued at four day intervals until the fruits were completely ripe (34 days). It was shown that the values for the diameter, mass, soluble solids and anthocyanins increased up to 30 DAF, whereas the soluble pectin content and ratio (relationship between soluble solids content and titratable acidity) increased up to 34 DAF. The respiratory rate showed the opposite behavior, reducing up to 30 DAF, and the values for firmness and chlorophyll reduced up to 34 DAF. The pH and ratio reduced up to 18 DAF with a subsequent increase up to 34 DAF, whereas the acidity showed the opposite behavior. In order to obtain high quality fruits with respect to ripeness it is important to consider the soluble solids and anthocyanin contents, which the present study showed to be indicators of the best moment for harvesting, that is, 30 DAF.
