[Fruit cracking: a review]

Abstract

Fruit cracking is a common physiological disease. Many fruits such as tomato, sweet cherry, apple, jujube, pomegranate, and litchi are liable to crack, causing considerable economic loss and agricultural resources waste. The mechanisms of fruit cracking are comprehensive. Some correlations have been observed between susceptibility of fruit cracking and some fruit traits (genetic, fruit size, fruit shape, fruit growth rate, water content, fruit skin characteristics, related gene expression, etc). Also, environmental condition (temperature, light, rainfall, etc) and orchard management (irrigation, sun-shade, mineral, growth regulator, etc) can influence fruit cracking. Here, progress in studies on fruit cracking is reviewed to provide a reference for prevention and control of fruit cracking.

Keywords: environment; fruit cracking; gene; genetic; influencing factors; orchard management; pericarp traits; water.
