| The purpose of this study was to identify the effect of delayed storage on the maintenance of the quality and on the control of pulp browning during cold storage of late peach cultivars. The fruit was harvested at the mature-green stage. All cultivars were exposed to temperatures of 20 ± 0.5ºC and 75 ± 3% of moisture in a cold room for 0.24, or 48 hours. Afterwards, the peaches were kept at 0 ± 0.5ºC and 92 ± 3% of R.H. for 28 days. In the end, the yellow pulp cultivars, regardless of temperature and length of delayed storage, did not present signs of internal browning and were of adequate quality for commercialization. When they were not subjected to delayed storage, the white pulp peaches presented pulp browning after 14 days of cold storage plus two... |

| The study was performed to identify the effect of delayed storage on the control of woolliness and leatheriness during cold storage of the late peach cultivars grown in Brazil. The fruits were harvested at the mature-green stage. All of the cultivars were exposed to temperatures of 20 ± 0.5ºC and 75 ± 3% of R.H. in a cold room for 0, 24, or 48 hours. Afterwards, the fruits were kept at 0 ± 0.5ºC and 92 ± 3% of R.H. for 28 days. The yellow pulp peaches, regardless of the length of delayed storage, did not present any symptoms of woolliness or leatheriness. The white pulp peaches not submitted to delayed storage developed either one or more of the other physiological disorders. Due to their lower level of pulp firmness, the control fruits of ‘Chimarrita’ and... |

| Abstract The pitahaya (Hylocereus undatus) is highly perishable and susceptible to chilling injury (CI) The objective of this study was to measure a set of biochemical, physiological, physical-chemical and physical variables in gradually chilling injured pitahaya fruits and assess the degree of correlation of each one with this damage. Pitahayas were stored at 2 or 7±1 °C and 90±6 % RH for up to 30 d, and then held at 22±4 °C and 60±8 % RH for up to 7 d. A visual evaluation of CI was conducted using a five point hedonic scale after storage and transfered to 22 °C. Titratable acidity (TA), total soluble solids, TSS/TA ratio, superoxide dismutase activity (SOD), glutathione activity (GR), piruvate decarboxylase (PDC), alcohol deshydrogenase activity (ADH),... |

| Se evaluó el patrón de maduración y el efecto del 1-metilciclopropeno (1-MCP), metil jasmonato (MJ), ethrel y choques de CO2 para reducir los daños frio (DF) en frutos zapote mamey procedente de huertas comerciales de Alpoyeca, Guerrero, México. Los frutos se almacenados por 7, 14 y 21 d a 10ºC y madurados a 23ºC. El patrón maduró 9 y 10 d después de la cosecha, incrementando SST (12,51% a 30,16%), pérdida de peso de 1,067% por día, disminución de la firmeza (38.76 N a 0.84 N), color de naranja moderado a naranja fuerte, mostrando un patrón climatérico con preclimaterio de CO2 y etileno de 26,45 mL kg-1 h-1 y 15,84 µL kg-1 h-1 y máximos de 156,40 mL kg-1 h-1 y 222.69 µL kg-1 h-1 a los 6 d de transferirlos a 23ºC. Las dosis de 600 y 900 nL L-1 de... |

| En México el fruto de zapote mamey es consumido principalmente en fresco debido a sus características organolépticas y nutricionales. Su consumo en fresco es apreciado en muchos países de América Central y del sur de los Estados Unidos de Norteamérica. Sin embargo, debido a la escasa información sobre su manejo en campo, cosecha, postcosecha y la aplicación de tecnologías postcosecha su comercialización es limitada. De 1970 a la fecha se ha iniciado la investigación en esta especie, principalmente en la propagación vegetativa, crecimiento de fruto, evaluación de la maduración en postcosecha, tecnologías postcosecha como: refrigeración, atmósferas modificadas y controladas, aceleradores o inhibidores de la maduración, así como el control de plagas... |

| Los experimentos se efectuaron en dos huertas comerciales de limón mexicano, ubicadas en Tecomán, Colima, México, durante los años 2003 y 2004. En ambos casos se determinaron los efectos de las aplicaciones precosecha, con diferentes concentraciones de reguladores del crecimiento, sobre el follaje de árboles de limón; en el primer año se probaron concentraciones de ácido giberélico (30, 20 y 10 mg∙L-1) y en el segundo año se aplicaron combinaciones de ácido giberélico, AG3 (Biogib®), N6-benziladenina (BA) (SIGMA) y ácido-3-indolbutírico (AIB) (SIGMA). Las concentraciones usadas de AG3 fueron 10 y 20 mg∙L-1 y en BA y AIB 5 y 15 mg∙L-1. En ambos experimentos el efecto de los reguladores de crecimiento se evaluó durante la poscosecha al final de su... |

| Se estudió el efecto del tratamiento de cuarentena (1.5°C/17d) autorizado para el control de mosca del mediterráneo (Ceratitis capitata Wied) en pomelo ‘Rio Red’. Sin embargo, al ser un fruto de clima tropical presenta alta sensibilidad a la refrigeración, lo que puede inducir una serie de alteraciones fisiológicas (daños por frío), que reducen significativamente su calidad. Es por esto que se evaluó la eficiencia de algunas tecnologías que promueven resistencia al frío y con esto mantener la calidad del fruto tras ser sometidos a tratamientos con bajas temperaturas con fines de almacenamiento y/o transporte. Las tecnologías evaluadas fueron: Acondicionamiento del fruto a 17° C por 7 días, Encerado (frutos tratados con una cera comercial conteniendo 14%... |

| Abstract: The objective of this work was to evaluate the influence of harvest at maturity on the composition, quality, and postharvest life of zapallito squash (Cucurbita maxima var. zapallito). Fruit were harvested at three developmental stages - small, medium, and large, with 30, 70, and 90±10-mm diameter, respectively - and were stored at 0 and 5°C for 26 days and, then, at 20°C for 2 days. The following parameters were determined: respiration, firmness, color, chlorophyll content, carotenoids, sugars, acidity, phenolic compounds, antioxidants, decay, mass loss, and chilling injury (CI). Small light-colored squashes were more prone to dehydration and decay. Delaying harvest markedly reduced fruit carotenoid contents, acidity, and respiration rate;... |

| The postharvest conservation of cut Heliconia flowers is an important factor to the success of commercialization, especially with regard to exportation. In the present study, the maximal storage time of cut inflorescences of Heliconia bihai cv. Lobster Claw at two different temperatures (12 and 19 °C) was evaluated and compared to laboratory conditions (25 °C, control treatment). Changes in visual quality, fresh weight and bract color (L*, a* and b*) were determined. The visual quality of the inflorescences and fresh weight decreased with time in all treatments. Symptoms of chilling injury were observed on the inflorescences stored at 12 °C for six and eight days. Bract color was not affected by temperature, storage time or the senescence process. The... |

| 'Douradão' peach is a perishable product and when cold stored is subject to chilling injury. The objective of the experiment was to evaluate the effect of modified atmosphere packaging (MAP) and cold storage on quality and storage life of these peaches. Fruits were packed in polypropylene (PP) trays and placed inside low density polyethylene (LDPE) bags (30, 50, 60, 75 μm thickness) with active modified atmosphere (10 kPa CO2 + 1.5kPa O2, balance N2). The control was made with peaches held in nonwrapped PP trays. Fruits were kept at 1 ± 1 °C and 90 ± 5% relative humidity (RH) for 28 days and CO2 and O2 within packages was monitored every two days. After 14, 21 and 28 days, samples were withdrawn from MAP and kept in air at 25 ± 1 °C and 90 ± 5% RH for... |

| The sensory, physical and chemical characteristics of 'Douradão' peaches cold stored in different modified atmosphere packaging (LDPE bags of 30, 50, 60, 75µm thickness) were studied. After 14, 21 and 28 days of cold storage (1 ± 1 ºC and 90 ± 5% RH), samples were withdrawn from MAP and kept during 4 days in ambient air for ripening. Descriptive terminology and sensory profile of the peaches were developed by methodology based on the Quantitative Descriptive Analysis (QDA). The assessors consensually defined the sensory descriptors, their respective reference materials and the descriptive evaluation ballot. Fourteen individuals were selected as judges based on their discrimination capacity and reproducibility. Seven descriptors were generated showing... |
