Description
Summary:Water rational use for garden irrigation is a constant concern in view of it waste, because researches have shown that it corresponds to 40 to 70% of the domestic consumption. One of the strategies employed to avoid this waste is the selection and planting of drought stress resistant plants. This research aimed to evaluate the Stenachaenium megapotamicum growth, a sub shrub plant, with ornamental potential, native from South Brazil, grown under different water regimes. Two experiments were developed: a) during the spring by applying three irrigation frequencies: daily, every other day, and every three days, b) during the fall / winter by applying four irrigation frequencies: daily, five, seven and nine days. Results obtained showed that S. megapotamicum is an adequate annual plant summer for landscape projects focusing in the efficient water use. Key words: estenaquenio, native, ornamental, landscaping, water saving, irrigation, water stress. O uso racional da agua para a irrigacao de jardins e uma preocupacao constante em face de seu desperdicio, pois pesquisas tem demonstrado que ela corresponde de 40 a 70% do consumo domestico. Uma das estrategias empregadas para evitar este desperdicio e o plantio de jardins com plantas resistentes a deficiencia hidrica. Nesta pesquisa, avaliou-se o crescimento de Stenachaenium megapotamicum, uma planta subarbustiva, com potencial ornamental, nativa da Regiao do Sul do Brasil, que foi cultivada sob diferentes regimes de irrigacao. Foram efetuados dois experimentos: a) na primavera, as plantas foram mantidas sob tres turnos de rega: diario, a cada dois dias e a cada tres dias; b) no outono/ inverno, as plantas foram mantidas sob quatro turnos de rega: diario, cada cinco, sete e nove dias. Os resultados obtidos demonstraram que S. megapotamicum e uma planta anual de verao adequada para projetos de paisagismo, focando no uso eficiente da agua. Palavras-chave: estenaquenio, nativa, ornamental, paisagismo, economia de agua, irrigacao, estresse hidrico.
