Durante el manejo postcosecha de flores de corte el uso excesivo de agua potable es común después de la cosecha, durante la selección-empaque y durante el transporte para evitar la deshidratación de los tallos florales. Los estudios de los beneficios de esta práctica de hidratación reiterada son escasos. El objetivo de este estudio fue evaluar el efecto del manejo con agua (húmedo) y sin ella (seco) después de la cosecha (fase I) y durante el almacenamiento refrigerado (fase II) en la vida de florero de los cultivares de rosa (Rosa hybrida) Blush, Freedom y Topaz, con importancia comercial. La hipótesis fue que el efecto del manejo seco de los tallos de rosa modifica la vida en florero en dependencia del cultivar. En la fase I un lote de flores de corte se mantuvo en condición seca y otro se colocó en contenedores con agua potable. En la fase II (los tallos permanecieron a 1±1 °C y HR 85 % por 7 d) cada lote se dividió en dos y se mantuvieron en condición seca y húmeda. Luego, la vida en florero se evaluó en los tallos a temperatura ambiente (20±3 °C y 56 % HR). Las variables evaluadas fueron biomasa fresca del tallo floral, apertura floral, apertura del poro estomático, unidades formadoras de colonias (UFC; bacterias) e incidencia de Botrytis sp. El diseño experimental fue completamente al azar, con 12 tratamientos formados por tres cultivares y cuatro combinaciones de manejo; la unidad experimental fue un tallo floral y se incluyeron diez por tratamiento. El tipo de manejo durante la fase II tuvo efecto mayor que en la fase I. La reacción de los tres cultivares fue similar a ambos tipos de manejo durante la fase I, pero el manejo seco durante la fase II aumentó significativamente la vida en florero. El efecto del manejo húmedo o seco en la fase I y II, en la vida en florero de tallos de rosa, es parcialmente dependiente del cultivar.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Water shortage is one of the main agricultural issues and alternative techniques are necessary to reduce its consumption. During the cut flowers post-harvest management, the excessive use of clean tap water is common after harvest, during the selection-packing process and during transportation to avoid dehydration of the flower stems. The studies about the benefits from this repeated hydration practice are scarce. The objective of this study was to evaluate the effect of the management with water (wet) and without it (dry) after harvest (phase I), during cold storage (phase II) and the vase life of rose cultivars (Rosa hybrida) Blush, Freedom and Topaz cultivars which have commercial importance. We hypothesized that the effects of the dry management of the rose stems modify the life in vase regard their cultivar. During phase I, a batch of cut flowers was kept in dry conditions and another placed in containers with clean tap water. At phase II (the stems remained at 1±1 °C and 85 % RH for 7 d) each batch divided in two and kept in a dry and wet condition. Then, vase life was evaluated on the stems at room temperature (20±3 °C and 56 % RH). The evaluated variables were the fresh biomass of the floral stem, floral opening, opening of the stomata pores, colony forming units (CFU, bacteria) and the incidence of Botrytis sp. The experimental design was completely randomized, with 12 treatments consisting of three cultivars and four management combinations each; the experimental unit was a floral stem from which ten were included per treatment. The management differences during phase II had a greater effect than in phase I. The three cultivars had similar reactions to both types of management during phase I, but dry handling during phase II significantly increased vase life. The effect of wet or dry management in phase I and II, in the vase life of rose stems, is partially dependent on the cultivar.]]></p></abstract>
