Pre-anthesis sprays of AVG reduced fruit number per raceme relative to racemes that were sprayed with the placebo (Fig. 3; P < 0.05) and relative to racemes sprayed post anthesis with
AVG (P < 0.05). At 3 weeks post anthesis, the average fruit number on racemes treated with AVG at 600 ppm was around 18 compared with 37 in the control. At 8 weeks post anthesis, fruit number per
raceme was 4.3 and 5.4 for 600 and 0 ppm, respectively
