Circadian rhythm of stem and fruit diameter dynamics of Japanese persimmon (Diospyrus kaki Thunb.) is affected by deficiency of water in saline environments.

Early diagnosis of water deficiency is essential to mitigate salt stress injury in plants. The effects of salt stress during the fruit growth stage on stem and fruit diameters of Japanese persimmon trees (Diospyrus kaki Thunb.) were measured by a micromorphometric technique under greenhouse conditions.
