| description | The limited availability of water due to agricultural, industrial, technological, and urban expansion requires a greater effort to make its use more efficient and achieve substantial savings in ornamental productions without affecting the commercial value quality, and final presentation of flowers and plants. Water stress is an environmental factor that causes physiological effects in plants and accelerates the senescence of leaves and flowers on cut stems. Considering crop evapotranspiration (ETc), an alternative way to reducing water consumption in intensive crops is the use of controlled, restricted irrigation, coupled with the application of phytohormones in pre-harvest to mitigate the effects of water stress, i.e. 6- Benzylaminopurine (6-BAP). The objective of this study was to determine the quality and vase life of Lilium stems under restricted irrigation combined with phytohormones application. An experiment with four treatments was designed, concerning normal (NI, 100% ETc) or restricted irrigation (RI, 35% ETc) and with or without application of 6-BAP (300 ppm). A completely randomized ANOVA design with 6 repetitions per treatment was used. The vase life of cut Lilium flowers was not significantly affected (13.9 vs. 12.5 days under NI and RI respectively). The application of 6-BAP had no influence on vase life, but delayed the foliage yellowing and therefore reduced the rate of deterioration of the floral stem. Restricted irrigation and the application of phytohormones can be useful tools to improve the water use efficiency in lily crops. |

A limitada disponibilidade de água devido ao desenvolvimento agrícola, industrial, tecnológico e urbano exige um maior esforço para tornar seu uso mais eficiente e obter economía substancial nas produções ornamentais, sem afetar o valor comercial, a qualidade e a apresentação final das flores e plantas. O estresse hídrico é um fator ambiental que causa efeitos fisiológicos nas plantas e acelera a senescência de folhas e flores em hastes de corte. Considerando a evapotranspiração das culturas (ETc), uma forma alternativa de reduzir o consumo de água nas culturas intensivas é o uso de irrigação controlada e restrita, somada à aplicação de fitohormônios na pré-colheita para mitigar os efeitos do estresse hídrico, por exemplo, 6-benzilaminopurina (6-BAP). O objetivo deste estudo foi determinar a qualidade e vida de vaso de hastes de Lilium sob irrigação restrita combinada com aplicação de fitohormônios. Foi delineado um experimento com quatro tratamentos, em irrigação normal (NI, 100% ETc) ou restrita (IR, 35% ETc) e com ou sem aplicação de 6-BAP (300 ppm). Foi utilizado um delineamento ANOVA inteiramente casualizado com 6 repetições por tratamento. A vida de vaso das flores de corte de Lilium não foi afetada significativamente (13,9 vs. 12,5 dias com NI e RI, respectivamente). A aplicação de 6-BAP não influenciou na vida de vaso, mas retardou o amarelecimento da folhagem e, portanto, reduziu a taxa de deterioração da haste floral. A irrigação restrita e a aplicação de fitohormônios podem ser ferramentas úteis para melhorar a eficiência do uso da água nas culturas de lírios.
