| Abstract:
We studied the initiation of minute cuts and the development of fruit cracking in cherry tomato. Cherry tomato plants (cv. Sun Cherry, Mini Carol and Akakokko) were cultured hydroponically. The counts and length of minute wedge-shaped cuts that appeared on the surface of fruit epidermis adjacent to the base of calyx were checked every week after anthesis. And at the time of fruit harvest, the rates of cracked fruit were recorded. The first occurrence of minute cuts was recognized at 2 weeks after anthesis. Their counts and length increased every week. The cultivar differences in the counts of minute cuts and in the rate of cracked fruit were recognized. The cultivar in which the ratio of minute cut length to fruit circumference was high, showed the higher rate of cracked fruit at harvest. Thus, occurrence of minute cuts was useful to clarify sensitivity of fruit cracking among different cultivars of cherry tomato. | |
