Grapevine Training Systems: Classic Trellis Diagram for Viticulture #234800 (License: Personal Use)

This 19th-century-style line drawing depicts a mature grapevine trained horizontally along two wires (a double curtain or bilateral cordon system), with labeled points indicating spurs (s), canes (d, g), trunk (i), and fruiting zones. Clusters of grapes hang from shoots emerging at regular intervals, demonstrating proper pruning and canopy management for optimal yield and sun exposure. The illustration serves as an educational reference for traditional viticultural practices.
