Schrank D-67273 Dackenheim, Weisenheimer Straße 38 Preserving wine growing areas on steep slopes is declared a common denominator among the general public and a land- scaping concept is needed. The ornamental vineVitis coignetiae is suggested to vegetate abandoned vineyards. The propagation potential of phylloxera on V. coignetiae Pulliat was assessed in an in vitro study comparing it with the rootstock Teleki 5C (V. berlandieri x V. riparia) and V. vinifera cv. 'Cabernet Sauvignon'. The results show that V. coignetiae has similar host capacities as V. vinifera for leaf-feeding phylloxera and thus may be considered a substitute pertaining to grape phylloxera resistance. The potential management of abandoned steep slopes withV. coignetiae is discussed and further arguments referring to ecological and landscaping effects are given to serve as decision-making support.
