Japanese persimmon cultivars (3 nonastringent, Fuyu, Jiro and Ichi Kijiro and 2 astringent, Aizumi Shiraza and Giambo) were evaluated during maturation for changes in delayed light emission (DLE) and physical and chemical properties relating to maturity. Firmness, chlorophyll and DLE decreased during ripening and Hunter a values, soluble solids and β‐carotene increased. For all cultivars the relationship between DLE and maturity, indicated by calculated maturity index, was linear and negative. High correlations between DLE and maturity indicated that DLE has high potential for use as a rapid, nondestructive technique for estimating persimmon maturity.
