DETERMINATION OF MECHANIC HARVESTING PARAMETERS OF SOME CULTUVATED PLUM VARIETIES IN REGION EĞİRDİR

Determining some of the tree and fruit properties is necessary in order to design or select machines for plum fruits harvesting and harvesting with mechanical methods. According to investigation; fruit detachment force, rates of mass percent fruit detachment force, bio-rupture force values, pH, titration acidity, total soluble solids, color (hº) were measured for Angelino variety plum in October 2, 2008 and President kind plum in September 25, 2008. The values were found as 6.40 N, 14.21, 4.54 N, 3.71, 0.89 %, 17.17%, 324.97 for Angeleno variety and 12.67 N, 7.46, 6.51 N, 3.69, 0.57 %, 22.64%, 339.93 for President variety respectively. The height of tree, the diameter of crown, the height and the diameter of body, coefficient of limb spring rigidity for 4.0 – 4.5 cm limbs in diameter were found as 509.82 cm, 397.13 cm, 55.94 cm, 12.46 cm, 326.10 N.cm-1 for the plum tree Angelino and 542.50 cm, 423.69 cm, 52.94 cm, 45.94 cm, 12.46 cm, 12.01 cm, 151.72 N.cm-1 for plum tree President respectively.
