Figure 7.3. Gross effects of hedging shoot-positioned, vertically upright-trained canopies (A), compared with hedging of nonshoot-positioned canopies (B). The benefits of hedging on fruit zone ventilation (and exposure) are likely to be greater with (A) than with (B).
Two illustrations of grapevine canopies: A shows dense, upright-positioned branches; B shows a spreading, irregular formation.
