| الوصف: | For six years, different field trials were used to examine the effect of irrigation on the yield and fruit quality of Sauvignon blanc grapevines in Marlborough, New Zealand. Control vines were given irrigation volumes equivalent to 100 % of ETcrop (IR100), minus an allowance for effective rainfall. Different levels of regulated deficit irrigation (RDI) were applied to other vines. Treatments varied from 80 % (IR80) to 0 % (IR0) of the control irrigation volume. During the first two years of the trial, soil moisture content (SMC) of the control vines was maintained above 0.20 L L-1. In subsequent years, SMC was gradually lowered from 0.20 L L-1 at flowering to 0.10 L L-1 from veraison through to harvest. In only one year (2004/05), a significant difference in yield was found when IR100 and IR20 both yielded>8 kg vine-1 compared with IR80 vines where yields were> 6.5 kg vine-1. We attribute this lower yield to smaller bunch weights. Minor differences in berry quality attributes were also observed in just one season (2006/07) when oBrix at harvest was significantly higher for IR100 compared with the other treatments. Also sensory analysis revealed only minor influences of irrigation treatments within single years, but large differences between years. The year to year variation in yield, juice quality and sensory aspects suggested that a change in climate might have a greater impact on wine character compared with irrigation effects. Unravelling the cause for these changes is the focus of our research programme. |
