ResumoCom o objetivo de quantificar o crescimento e o acúmulo de macro e micronutrientes da cultura do quiabeiro, no decorrer do ciclo, e obter equações que melhor os representem, um experimento foi realizado de 14 de janeiro a 14 de maio de 2009, na UNESP Câmpus de Jaboticabal, SP. A cv. Santa Cruz 47 foi semeada diretamente no sulco, em espaçamento de 1 x 0,2 m. No decorrer do ciclo, realizaramse coletas aleatórias de plantas com intervalos de quinze dias. As médias foram ajustadas às equações de regressão polinomial e de modelos não lineares. A partir de 50 dias após a semeadura (DAS) houve grande aumento no acúmulo de matéria seca nas partes da planta. Na colheita final, 120 DAS, as folhas, hastes e frutos representaram 21, 71 e 8%, respectivamente, da matéria seca total da planta. A sequência decrescente de acúmulo de nutrientes pelo quiabeiro foi K, Ca, N, Mg, P, S, Fe, B, Mn, Zn e Cu, o equivalente a 6. 002,8; 4.733,8; 2.930,8; 1.196,3; 473,7; 436,2; 49,82; 10,4; 7,1; 7 AbstractWith the objective to quantify the okra crop's growth and macro and micronutrients accumulation during its life-cycle obtaining equations that best represent it, an experiment was carried out at Jaboticabal city, SP, Brazil, from January 14 th to May 14 th , 2009. The cv. Santa Cruz 47 was directly sowed into open soil furrows, in a spacing of 1 x 0,2 m. During the life-cycle were realized random samples of plants at 15 days intervals. The means were adjusted to polynomial regression equations set of non-linear parameters. After 50 days from sowing there has been a large increase of dry matter in plant' parts. At the final harvest, 120 days after sowing, the leaves, stems and fruits accounted for 21, 71 and 8%, respectively, from the total plant dry matter. The decreasing sequence of nutrient accumulation was K, Ca, N, Mg, P, Fe, B, Mn, Zn and Cu equivalent to 6,002.8; 4,733.8; 2,930.8; 1,196.3; 473.7; 436.2; 49.8; 10.4; 7.1; 7.1 e 1.5 mg plant -1 . The quantity accumulated of culture were 146.5; 23.7; 300.1; 236.7; 59.8 e 21.8 kg ha -1 of N, P, K, Ca, Mg and S, respectively, and 520.0; 76.0; 2,491.0; 355.0 e 355.0 de B, Cu, Fe, Mn and Zn, respectively.

RESUMO -O trabalho teve como objetivo avaliar a qualidade pós-colheita de três cultivares de uvas de mesa sem semente submetidas ao processamento mínimo e armazenadas sob refrigeração e à temperatura ambiente. Para tanto, foram utilizadas uvas das cultivares BRS Clara, BRS Linda e BRS Morena, produzidas na Embrapa Uva e Vinho/Estação Experimental de Viticultura Tropical, em Jales-SP. Os cachos, depois de higienizados e imersos em água clorada a 200 mg de cloro.L -1 por 5 minutos, foram mantidos em câmara fria, a 12ºC, por 12 h. As bagas foram degranadas e lavadas em solução de álcool a 70%, por 5 segundos. Depois de escorrido o excesso da solução alcoólica, as bagas foram acondicionadas em bandejas de tereftalato de polietileno (PET) transparente com tampa e com capacidade para 500 mL. Cada unidade, contendo 200 g de bagas, foi armazenada a 12±1,8ºC e 24±0,8ºC, por 12 dias. Avaliaram-se, a cada três dias, a perda de massa fresca, a aparência, a coloração e os teores de sólidos solúveis (SS) e de acidez titulável (AT). A temperatura de 12°C manteve a turgidez, a coloração, as qualidades organoléptica (relação SS/AT) e comercial das bagas das três cultivares testadas, por nove dias, enquanto no armazenamento à temperatura ambiente (24°C), ocorre perda da qualidade comercial das bagas aos três dias para as cvs. BRS Clara e BRS Linda, e aos seis dias para a cv. BRS Morena. Termos para indexação: Vitis sp., uvas sem sementes, pós-colheita, processamento mínimo. EFFECT OF STORED TEMPERATURE IN MINIMALLY PROCESSED SEEDLESS TABLE GRAPESABSTRACT -The objective of this research was to evaluate the postharvest quality of three apirenic (seedless) table grapes cultivars submitted to minimally processed and stored under refrigeration and room temperature. It was used the cultivars BRS Clara, BRS Linda and BRS Morena produced at Embrapa Grapes and Wine/Tropical Viticulture of Experimental Station, in Jales, state of São Paulo. The clusters were immersed in a solution of sodium hypochlorite (200 mg Cl.L -1 ) for 5 minutes before being stored at 12ºC for 12 hours. The berries were removed and rinsed with alcohol solution (70%) per 5 seconds. After drained the water excess, the berries were conditioned in 500 mL capacity trays of transparent tereftalato of polyethylene (PET) with lid. Each unit with 200 g of berries was stored at 12±1.8ºC and 24±0.8ºC during 12 days. Every three days, the loss of weight, appearance, color, soluble solids (SS) and titratable acidity (TA) were evaluated. The temperature of 12°C kept the turgidity, the color, the ratio SS:TA and the marketing conditions of the berries from the three cultivars tested after nine days of evaluations. The berries stored at room temperature (24°C), loss the commercial quality at the third day for BRS Clara and BRS Linda cultivars and at the sixth day for the BRS Morena cultivar.

The aim of the present study was to evaluate the effect of the application of hyperbaric pressure at room temperature (23 ± 1°C) for 2, 4 or 6 d, followed by 2 d under ambient conditions (23°C, 50% relative humidity, 100 kPa), on the physical, chemical and metabolic characteristics of the tomato cultivar 'Débora'. The following pressures were tested: 100 (control), 200, 400, 600 and 800 kPa. Tomatoes subjected to 600 or 800 kPa for 6 d presented lower weight loss (up to 80%) and 1.2 times greater firmness than control tomatoes. Hyperbaric pressure did not decrease the tomato respiration rate. However, the initial tomato color was maintained with increasing applied pressure, and pressure decreased tomato lycopene synthesis by up to 57%. Normal tomato ripening was not negatively affected by the application of hyperbaric pressure. The present results show that application of hyperbaric pressure up to 800 kPa at 23°C delays the ripening of the tomato cultivar 'Débora' and results in longer shelf life.
