Low concentration fumigation with nitric oxide (NO*) has been shown to extend the postharvest life of a range of flowers, fruits and vegetables by down-regulating ethylene production. Since ethylene is involved in flower abscission and leaf senescence of `John Fanick' phlox cut flower heads, a superior selection of perennial phlox (Phlox paniculata L.) bearing attractive long-lasting flowers, we have evaluated the effect of NO* delivered in vivo using sodium nitroprusside (SNP) as the source of NO* donor, on postharvest performance of `John Fanick' phlox flower heads. Although the presence of SNP (10-200 μmol·L-1) in the vase solution promoted the abscission of the open flowers, the young flower buds continued to open even in the presence of high SNP concentrations. On the other hand, at high SNP concentrations, the leaves became either yellow, or more frequently turned progressively black and senesced. Inclusion of sucrose in the vase solution, or pretreatment of flower heads with either 1-MCP or STS, significantly delayed the abscission of flowers and blackening of leaves. The pretreatment of flower heads with either 1-MCP or STS, or the presence of sucrose in the vase, together with SNP, greatly reduced the toxicity of the latter chemical resulting in improved postharvest display life. These results indicate that in `John Fanick' the leaves are relatively more susceptible to NO*-induced toxicity than the flowers. However, both sucrose and ethylene perception inhibitors are able to minimize the toxicity of high concentrations of NO* delivered in vivo via SNP.

Broccoli (Brassica oleracea), green bean (Phaseolus vulgaris), and bok choy (Brassica chinensis) were fumigated with nitric oxide (NO) gas in air or in nitrogen for 2 hours at 20°C (68.0 °F), then stored at 20 °C in humidified air containing 0.1 μL.L-1 (ppm) ethylene. The postharvest life of all vegetables was extended by NO although the concentration of NO required and the magnitude of the extension varied between produce ranging from 14% for green bean to more than 50% for broccoli. NO uptake by produce from air was not significantly different than from nitrogen at the lower effective NO concentrations, but NO uptake was less from air at the highest concentration used for broccoli. Application of NO in an air atmosphere is considered a feasible, more convenient treatment regime for horticultural produce than use of a nitrogen atmosphere.

Nitric oxide (NO) acts as anti senescence substance, which may extend the postharvest life of fruits, vegetables and flowers when they are treated with micro molar concentrations of compounds like the donor sodium nitroprusside (SNP). This work aimed to evaluate the effect pulsing or spraying of NO on the longevity of cut Epidendrum ibaguense inflorescences. After harvested, the inflorescences were pulsed for 6, 24 or 48 hours with 5, 10, 50, 100 and 500 µM SNP or sprayed until run off with the same mentioned solutions. Controls were treated with distilled water. After the treatment, the flowers were placed in deionized water, which was changed every 2 days. No significant differences were observed on the longevity of flowers treated with 5, 10, 50 or 100 µM SNP, regardless of the mode of application. Inflorescences treated with 500 µM SNP had reduced longevity and increased flower abscission. In inflorescences kept in SNP solution, toxic symptoms such as darkening of the labellum resulting in reduced longevity compared with the control. The longevity of inflorescences sprayed with 500 µM SNP reduced from 6.8±0.57 to 5.1±0.82 days. Collectively, NO treatments were not able to extend the shelf life of E. ibaguense inflorescences and high concentrations of the NO donor compound in vase solution or spraying leads to toxicity symptoms on the flower labellum.

Strawberries and iceberg lettuce were fumigated with nitric oxide gas in air containing 2 and 5% oxygen, followed by storage at 5 and 10°C, respectively, in the same atmosphere. The postharvest life of strawberries and lettuce was significantly increased by fumigation with nitric oxide or storage in low oxygen, respectively. When both treatments were applied there was no additional increase in the postharvest life of lettuce arising from the NO and in that of strawberries from the low oxygen. However, fumigation with NO and storage in elevated carbon dioxide and reduced oxygen resulted in the greatest extension in postharvest life for both produce with the increase over air storage being about 250% for strawberries and 100% for lettuce.

El tomate es la hortaliza de fruto más cultivadas a nivel mundial. De esta existen múltiples genotipos, que están genéticamente creados para condiciones ambientales muy específicas, por ello es importante conocer el comportamiento postcosecha de los frutos, que resultará en el cultivar mejor recomendado para cada región. El objetivo general fue: realizar la caracterización fisicoquímica y postcosecha de tres genotipos de jitomate, cultivados bajo condiciones de invernadero, en Tehuacán Puebla, México. La investigación se llevó a cabo en laboratorio. Los genotipos fueron: Merlisse, Maxcesa y Komet tipo bola, cultivados bajo invernadero. Las variables respuesta fueron: diámetro ecuatorial y polar, dinámica del peso de fruto, color de fruto, firmeza, contenido de Ca++ y K+ y vida postcosecha. El diseño utilizado fue completamente aleatorizado, cuyos tratamientos fueron los cultivares y siete repeticiones (3 x 7)= 21 unidades experimentales. Los resultados indican, que el mayor diámetro ecuatorial y polar así como pérdida de peso, fueron en Maxcesa, mientras que Komett, presentó la mayor firmeza y contenido de Ca++ y K+, siendo este último quien presentó la mayor vida de anaquel. De esta investigación se puede concluir, que el cultivar Komett, es quien mejor se adapta a las condiciones del valle de Tehuacán, Puebla.
