You should leave 10 mm of space above the abstract and 15 mm after the abstract. The heading Abstract should be typed in bold 9-point Arial. The body of the abstract should be typed in normal 9-point Times in a single paragraph, immediately following the heading. The text should be set to 1.15 line spacing. The abstract should be centred across the page, indented 15 mm from the left and right page margins and justified. It should not normally exceed 200 words. Under this problematic context, several growers in our area proposed alternatives to conduction systems. An innovation was the system of divided canopy “Ramé”, developed by the local viticulture Luis Alberto Ramero. This system was attempted to combine high yield with high quality grape, machanize harvest and good cinditions of canopy microclimate. It's a system of vertical shoot position, with its canopy divided into two planes. These systems are characterized, in our region, by a low foliar surface exposed per hectare, a relatively low productivity (in the case of the VSP) or difficulty to mechanize the harvest (in the case of the Parral). The objective of this study was to evaluate the ecophysiology of Rame system, determining if it behaves differently when it is planted with one or two plants by post (Rame single and double). Also the two modalities of Rame were compared with the trellis in VSP. Since this latter system is not included in the statistical, but planted design on the side of the test, the comparison kept a descriptive character. For the Rame we established an experimental trial with statistical design, with two treatments in trellis-training system. A treatment consisted in planting one vine per post, called simple Rame (RS) and two vines per post, called double Rame (RD), leaving in this way different number of plants per unit area (1600 plantas / has and 3200 plantas / has respectively). Nevertheless, regardless of the number of plants per hectare, Rame system maintain high values of anthocyanins (1, 2 mg/Kg of grapes) and IPT (43) with high production (152 qq / has). This fact, added to that the system has potential for mechanization, converts Rame in a trellis system with high potential for vine growth in the viticulture regions. The trellis VSP behaved less productive (86 qq / has), and at the same time obtained lower values of qualitative components such as anthocyanins (1.04 mg/Kg of grapes) and IPT (35).
Résumé
ReLos sistemas de conducción más difundidos en Argentina son los de canopia simple, tanto de desarrollo horizontal, caso de los parrales, como de desarrollo vertical, en los espalderos. En la actualidad predomina el parral, existe un crecimiento significativo de espalderos altos en superficie cultivada. Bajo este contexto problemático, varios viticultores de nuestra zona propusieron modificaciones a los sistemas de conducción. Una innovación fue el sistema de canopia dividida “Ramé”, desarrollado por el viticultor mendocino Luis Alberto Ramero. Lo que este viticultor buscaba era poder tener mayores rendimientos (equiparables a los de un parral), manteniendo una alta calidad enológica de uva. También, poder colocar tela antigranizo de manera económica y mecanizar la cosecha mediante una máquina diseñada ad hocque sacude los cordones secundarios. El objetivo de este trabajo fue evaluar ecofisiológicamente el sistema Ramé, determinando si se comporta en forma distinta cuando es plantado con una o dos plantas por poste (Ramé simple y doble). Para su evaluación se realizaron distintas mediciones, dentro de ellas nos enfocamos en superficie foliar Total por producción de uva, producción por planta y composición de Antocianos e IPT (Índice de polifenoles totales). No se encontraron diferencias significativas en ninguna de las variables medidas para los dos tratamientos. Sí se pudo observar que el sistema, independientemente del número de plantas por has, mantiene valores altos de Antocianos (1.2 mg/Kg de uva) e IPT (43) con alta producción (152 qq/Ha). Esto sumado a que el sistema tiene posibilidades de mecanización, se puede concluir que es un sistema de conducción con altas posibilidades de crecimiento en el medio.
