When apples are picked or selected by grader, the rate of wound occurrence on the skin by apple stalk is remarkably high if the apple was bigger than 3 size during the harvest time. Except this case, the other sizes showed very little similarity. The crop of apple per 1 minute was 2.9kg without cutting fruit stalk, whereas only 1.1kg of the apples were obtained due to cutting the fruit stalk. Thereby, the harvesting without cutting fruit stalk is highly effective in terms of productivity rather than cutting the fruit stalk. As far as the wound occurrence rate on apple skin by apple stalk of distance between grader's dish and accumulated board is concerned, the grader which has no distance showed quite low rate of wound occurrence compared with those grader with 3cm or 8cm distance. When the apple was being stored, there was no difference in firmness between the cut stalk apple and the uncut stalked apple, however there was slightly more weight loss in the cut stalk apple than uncut stalk apple.
