Fruit cracking of sweet cherry fruit due to rain near harvest is a major source of crop loss in the cherry industry. The objection of this study was to understand the sweet cherry fruit cracking. Depending on the year, the disorder is characterized by a cracking of the outside layer of the cherry skin, as called cuticle. The crackings were appeared around the stem end, where water could accumulate, but was also seen fruit side or apical end. The cracking was observed mostly in the fruit apical end in 2004 and around the stem end in the other years. It had more rainfall at early season of fruit growth, early May, in 2004 and 2006 compared to other years. Those years showed higher rates of the fruit cracking occurrence. The hypodermal layer was examined on cracking susceptible cultivar, 'Sato Nishiki' from young to mature fruit cuticle. The hypodermal layers of the stem end area were decreased by one to two layers and fruit apical end area was cracked as fruit development. When fruits were immersed in distilled water, the larger fruit (> 6 g) had more cracking ratio than smaller fruits (< 4.5 g).
