Diospyros kaki Thunb. 'Zhongshi 3' for both fruits and ornamentals
Persimmon (Diospyros kaki Thunb.) is a deciduous tree in the family Ebenaceae and is well-adapted in tropical, subtropical and temperate areas. The persimmon is a famous woody grain tree for its high fruit yield and high content of soluble solid in fruits. The morphology of fruits among persimmon cultivars is diverse, and the fruit color is red or orange red in autumn. The persimmon leaves are green or dark green in summer, and turn to red in autumn. The pretty leaves and fruits make persimmon to be an important ornamental. Most persimmons are hexaploid, thus the persimmon species (Diospyros kaki) contain a plenty of variation, which leads to more than 1000 persimmon cultivars. The diversity of leaf color among persimmon cultivars is one of the signs that reflect the genetic diversity. In July 2009, the Diospyros research group of Paulownia Research & Development Center found a variant persimmon tree with special leaf color, which significantly differed from other trees. The tree was photographed and the morphological characters of leaves were determined. The book named ‒ Guidelines for the conduct of tests for distinctness, uniformity and stability-persimmon (Diospyros kaki Thunb.) (Gong, 2006) does not contain the description of leaf color. The book named ‒ Descriptors and data standard for persimmon (Diospyros spp.) (Yang and Wang, 2006) shows that the color of leaves on one-year-old branches can be yellow, yellow green, green, dark green, green with light brown, brown green or green with light red. It is normal that the leaf color of a single tree contains 1 or 2 types in current persimmon accessions, whereas no report reflects that more than 2 color types contained in a single tree and appeared in layer.
