The effect of shade on flower drop (monitored from full bloom
until 6 mm berry size) was significant (p-value ≤ 0.01) in trial 1 but
not in trial 2 (Table 2). The growth regulator produced no signifi-
cant effect on natural flower drop percentages in none of the trials.
Flower drop ranged from 78.6% in GAc-1 ppm to 90.6% in S50B-
90% in trial 1, while the mean flower drop was 73.6% in trial 2.
