Resumo: | The almost complete absence or misdistribution of water as a natural resource frequently constitute a limiting factor for plant growth and development in the semi-arid northeastern Brazil. In this context, the use of appropriate irrigation techniques is an essential and indispensable factor for proper functioning of the primary and secondary metabolisms in plants. This study aimed to assess the metabolism of the Syrah grapevine in the semi-arid northeastern Brazil, by using three irrigation strategies (controlled deficit irrigation [CDI], deficit irrigation [DI], and full irrigation [FI]). The research was conducted at Embrapa Semiarid (Embrapa-Brazilian Agricultural Research Corporation), Experimental Field of Bebedouro, municipality of Petrolina, state of Pernambuco, Brazil. The statistical design was randomized blocks, with a 3 × 6 factorial scheme. Six samplings were performed throughout the experiment cycle at 54, 60, 73, 87, 101, and 115 days after pruning (DAP). We analyzed the total soluble sugars, reducing sugars, total soluble protein, and invertase activity. Analysis of variance and the F test were performed for all analyzed variables. The means were compared using the Tukey test at 5% significance. At the end of the experiment cycle, DI was found to increase the average acid invertase activity in the plant cell wall. Further, by the end of the experiment cycle, the total soluble sugars and reducing sugars increased in all plants in the three irrigation strategies. Thus, we conclude that it is possible to reduce water consumption in vineyards of the semi-arid northeastern Brazil, without significantly affecting the protein and sugar metabolisms in the plants. |

Neste contexto, o uso da técnica da irrigação se torna imprescindível como fator de produção essencial para um bom funcionamento do metabolismo primário e secundário das plantas. O presente trabalho teve o objetivo de avaliar o metabolismo da videira ‘Syrah’, sob três estratégias de irrigação no semiárido nordestino (Irrigação com Défice Controlado-IDC, Irrigação Deficitária-ID e Irrigação Plena-IP,). A pesquisa foi desenvolvida na Embrapa Semiárido, especificamente no Campo Experimental de Bebedouro, localizado no município de Petrolina-PE. O delineamento estatístico foi em blocos casualizados, em esquema fatorial 3 x 6. Foram utilizadas três estratégias de irrigação (IDC, ID e IP) e foram realizadas seis coletas ao longo do ciclo aos 54, 60, 73, 87, 101 e 115 dias após a poda (DAP). Foram avaliadas as variáveis: açúcares solúveis totais, açúcares redutores, proteína solúvel total e atividade das invertases. Realizou-se a análise de variância e o teste F para todas as variáveis, comparando as médias encontradas pelo teste de Tukey a 5% de probabilidade. A irrigação deficitária confere maior atividade média da invertase ácida da parede ao final do ciclo. Os açúcares solúveis totais e açúcares redutores aumentam para todas as estratégias de irrigação ao final do ciclo. É possível reduzir o consumo de água nos cultivos vinícolas do semiárido nordestino sem afetar significativamente o metabolismo de proteínas e açúcares.UEL2013-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1300710.5433/1679-0359.2013v34n6Supl1p3611Semina: Ciências Agrárias; Vol. 34 No. 6Supl1 (2013); 3611-3624Semina: Ciências Agrárias; v. 34 n. 6Supl1 (2013); 3611-36241679-03591676-546Xreponame:Semina.
