Fruit motion pattern
The percentages of fruits with stem at three vibration frequencies are shown in Table 2, which shows that 10 Hz vibration resulted in less fruits with stem. The detachment condition might be affected by motion patterns.
Fruit detaching time
the limb diameters at shaking position, average maturity level and average weight of harvested fruits, as well as fruit detaching time and cycles of each group. It can be seen that the limb diameter at the shaking position was very consistent.
