Data showed that 60 nodes per vine was the maximum threshold without decreasing fruit quality. "If you tell a grower that he could crop 25 percent more with the same quality, that's not as convincing as when you tell him that he can also reduce his pruning costs by 60 percent," Poni said. The Geneva double curtain trellis sys- tem, used in Italy since the 1970s, is well suited to mechanization, according to Poni. Italian growers using the Geneva double curtain can manage their vine- yards in less than 60 hours of labor per hectare (25 hours per acre). A control cluster of Trebbiano grapes without early leaf removal. Plastic bags that envelop the entire vine are used to measure gas exchange of the canopy.
