Laboratory tests on rose fruit mechanical shaking off
1998
Salomon, Z. (Research Institute of Pomology and Floriculture, Skierniewice (Poland))
The effectiveness of mechanical harvesting of rose fruits (Rosa canina and Rosa rugosa) was studied at four velocities of shoot movement, two amplitudes and four stroke frequencies of shaking fingers. The increase of shoot velocity resulted in a decreased number of detached fruits. At each velocity the efficiency of a fruit detachment increased with the increased of amplitude and frequency of a stroke. A higher density of comb spacing had a benificial effect on the efficiency of fruit shaking off in both species, while an increased number of fingers in the comb had no influence
